Introduction

Bosch Rexroth Oil Control (DCOC - Drive Control Oil Control) manufactures a wide range of solenoid and directional valves for different applications grouped by typology in the present catalogue.

For valves not included in this catalogue, please consult Bosch Rexroth Oil Control.

Technical Data

The solenoid valves are composed by:

high strength cast iron body, with control spool made of special heat treated steel for long-lasting performance; 1 or 2 oil immersed sole-noids and 1 or 2 coils made by copper wire winding, with isolating coating, optimized for high hydraulic performance with limited current absorption.

The directional valves bodies can be manufactured with different materials like high strength cast iron, steel or high strength wrought aluminium; their internal parts are manufactured with top quality steel processed with the most advanced machinery, which combines high production capacity with full and precise control of dimensions.

All external cast iron or steel parts are protected by zinc plating; aluminium parts are available with and without anodizing; special coating is available on request.

All solenoid valves are designed according to the highest specifi cations and are manufactured and tested with the most advanced machin-ery and equipment which combines high production capacity with full and precise control of dimensions.

Ports, when present, can be drilled according to different specifi cations like: G sizes (BSPP) according to UNI-ISO 228/1; Metric with O-Ring, or with fl at washer, according to UNI-ISO 6149; SAE threaded ports UN-UNF 2B; BSPP thread with O-Ring, according to JIS 2351-90 Type “O”.

Seals:

O-Rings: are made with acrylonitrile/butadiene, commonly called BUNA-N (or NBR, according to ASTM and ISO), standard for tempera-tures between -20°C and +80°C [-68°F and + 176°F]. Special O-Rings for higher temperatures can be supplied upon request.

Back-up Rings and Slide Rings are made of reinforced poly-tetrafl uoroethylene (PTFE), or BUNA-N (NBR) as well.

Quality System Approval Orders

DCOC distributes its valves through its sales network in compliance with the delivery terms shown in the specifi c documents. Customer orders must be transmitted to the Vendor in written form (via fax, telecommunication, or electronic means) and must contain the following information:

a) date and place of issue of the order;

b) exact name of the Customer company and its complete shipping and billing addresses;

c) a reference to the offer made by the Vendor company with the relevant agreed prices (if such an offer exists);

d) valid Vendor’s part numbers and description/specifi cation of all the products to which the order refers;

e) the required quantities;

f ) the quality requirements with which the Vendor must comply;

g) the signature of an authorized representative;

h) the required delivery date;

i) terms of payment;

j) shipping agent

For Customers supplied by DCOC directly, the orders are offi cially as accepted when the relevant order confi rmation, duly signed by DCOC, arrives at the Customer; or, if such a document is not forthcoming, orders will be considered confi rmed by the Vendor, at the terms requested, if they are not explicitly refused in writing within 10 working days from the order date.

NOTE: except if otherwise agreed with the Customer, DCOC can introduce technical modifi cations to the product specifi cations without notice; in any event, DCOC undertakes to execute customer orders/contracts which are already confi rmed without applying any modifi ca-tions to the product and/or anyway guaranteeing product interchange.

RA 15900-08/04.13 Product Selection Guide Hydraulics | Bosch Rexroth Corp. v

Product Quality and Compliance to the Specifications

All DCOC valves are subject to the necessary checks/tests in various production phases in order to guarantee compliance with the speci-fi cations and settings shown in the catalogues, drawings, and/or technical data sheets. The Customer may make visits to and to carry out Quality AUDITS at the Vendor’s plant, provided that a specifi c appointment is agreed.

Due to the wide range of variants and operating conditions of the equipment manufactured by the Customers, DCOC does not assume any liability for the results of tests performed by third parties. The Customer is therefore responsible for the fi nal choice of the valve and for the adoption of all the measures required to achieve the functional and safety specifi cations of the system in which the valve is to be installed, in addition to the compliance with any specifi c regulation or standard applicable to the system in question.

In the event of product non compliance due to Vendor’s mistake, in addition to the warranty coverage here described, the Customer can demand the Vendor to perform the necessary corrective actions in order to promptly improve its quality level.

Application Limitations

The Customer is expressly prohibited from using the products sold by the Vendor for purposes other than those specifi ed in the offer, catalogs, or technical documentation.

Specifi cally, DCOC ‘s Dealers or Agents are not authorised to approve the use of DCOC valves for the following applications:

− any passenger or goods carrying road vehicle or equipment subject to Highway Safety Standards and Directives, such as (without limita-tion) steering, or brake systems;

− aircraft or space vehicles;

− ordnance equipment;

− medical and health products, including life support equipment or vehicles;

− systems to be used under any Nuclear Regulatory Act or Regulation;

− systems for use in explosive or otherwise hazardous environments.

If the Customer intends to use the valves supplied for any applications falling into one or more of the above categories or other similar categories, or for any applications other than those expressly described in the documentation, or in case of doubts concerning the applica-tion, he must require prior specifi c authorisation directly from DCOC and proceed only after such authorisation has been issued in writing.

Any damage suffered by the Customer or third parties arising from failure to comply with the above mentioned terms and limitations, or due to non compliance to DCOC’s instructions/specifi cations shown in the catalogue pages or in the technical drawings, will be borne entirely by the Customer himself.

Customer's Obligations to Prevent Damages within His Own Production Process

If the valves are employed in a production process which could cause substantial damage to the Customer or to third parties in case of assembly line stopping as consequence of defects or lack of availability of valves, the Customer has the responsibility to maintain a safety stock in order to promptly replace the defective or missing parts; the Customer undertakes to engineer the production cycle so that the replacements can be carried out easily.

In any event, DCOC will be responsible for the repair or replacement of any part or valve found to be defective due to its own manufactur-ing causes.

Warranty

DCOC warrants the original purchaser of its valves that the products are free from defects in material and workmanship, when handled, installed and operated under normal conditions, in accordance with DCOC and Industry recommended practises, for a period of 12 months from the fi rst installation, provided that the installation date is within 6 months from the manufacturing date marked on the valve itself.

Seals and O-Rings are expressly excluded from the warranty.

This warranty is applicable only to the original purchaser of the valves, and is not transferable.

This warranty will not apply to products that have been subject to conditions of contamination in the customer’s hydraulic circuit, or to products which have been incorrectly handled, fi tted, used or modifi ed/disassembled without the Vendor’s supervision or authorisation.

In the event that the Customer believes that the valves or parts of valves supplied are defective for causes attributable to the Vendor, the Customer shall notify the alleged defects by sending a detailed written report, thereby allowing the Vendor to understand and verify the nature of the claimed defects, also through its authorised technical personnel.

Bosch Rexroth Corp. | Hydraulics Product Selection Guide RA 15900-08/04.13vi

vii

Once the defect has been analysed and after determination that the defect is attributable to the Vendor’s fault, DCOC will repair or replace the valve within a reasonable time and/or inform the Customer of the cause of such defect.

The DCOC warranty policy does not provide for refund or credit for the defective material; specifi cally DCOC shall not be held responsible under any circumstances for loss of profi t, costs of disassembly and reassembly of the product, nor for any damages connected with such operation, nor for any cost related to the fi tting of the repaired or replaced valves, including losses of earnings related to machine being temporarily out of service.

If the valve supplied is to be fi tted in assembly plants potentially capable of causing damages to third parties of magnitude signifi cantly greater than the cost of the valve itself, it is the Customer’s responsibility to adopt all the possible safety measures in order to avoid any such damages; in fact, the production of valves at competitive market prices cannot ensure the total absence of defects, in spite of DCOC’s continuous concern to provide top quality products. Should the Customer face the need of a Recall Campaign in which an DCOC valve is involved, DCOC’s involvement shall be discussed and agreed between DCOC and the Customer prior to the start of any action. Should the Customer face a problem connected with an DCOC valve and potentially capable to raise a “Product Liability” case, the Customer shall immediately notify the Vendor who will participate to the joint analysis of the problem, together with the Customer.

NOTE: any warranty condition or obligation different from this policy can be effective only if specifi cally agreed and undersigned by both Parties: Customer and Vendor.

Technical Assistance

DCOC guarantees to the Customer its availability to perform free of charge a joint analysis of any defect reported by end users, also when such analysis is to be carried out at the Customer’s site, provided that the timing is reciprocally agreed.

However, if the malfunction is found to be not due to DCOC’s responsibility, the Vendor will issue a debit note to the Customer for the cost of the services rendered. When the Customer requires the assistance of DCOC’s engineers on its sites, he shall make a written request to this effect (which can be transmitted also by e-mail or fax).

Statement

The valves described in this catalogue can be employed in systems or machines falling under the specifi cations of the EEC European Directive 2006/42/CE (Machine Directive) and later amendments. The valves shall not be operated, adjusted or disassembled before the complete machines are verifi ed to be in compliance with the requirements of the above mentioned Directive.

Applicable Law

For all matters that are here omitted, any delivery performed by DCOC directly will be subject to the applicable provisions of the Italian law.

If the Customer’s address is in a Foreign Country, any case of dispute, also of “International nature”, which should arise from these sales conditions shall be subject to the provisions of the Italian Law, with the sole competence of the Court of Modena – Italy.

ATTENTION

Limited to the valves and related products here included, this catalogue cancels and supersedes any prior issue.

All rights are reserved. It is specifi cally forbidden to reproduce partially or totally the present catalogue.

Principles of operation, cross section

The sandwich plate design directional valve elements B8_05… are very compact direct operated solenoid valves which control the start, the stop and the direction of the oil fl ow. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4). When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position “0” to the required end position “a” or “b”, and the required fl ow from P to A (with B to T), or P to

B (with A to T) is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position.

Each coil is fastened to the solenoid tube by a ring nut (6). A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

The sandwich plate design directional valve elements B8_45… are very compact direct operated solenoid valves which control the start, the stop and the direction of the oil fl ow. These elements basically consist of a stackable housing (1) with a control spool (2), two solenoids (5), and two return springs (4). The upper part of the housing is extended in order to provide space for the cavities where two PO check valves are fi tted. They consist of two calibra-ted balls (10), with return springs (11), which allow upstream fl ow but lock on the respective seats (9) and prevent the return fl ow. The return fl ow is possible when they are opened by the pilot piston (8), if enough pilot pressure is present in the opposite line.

When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position “0” to the required end position “a” or “b”, and the required fl ow from P to A (with B to T), or P to B (with A to T) is achieved.

Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool (2) returns in its neutral-central position.

Each coil is fastened to the solenoid tube by a ring nut (6).

A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool (2) returns in its neutral-central position.

The sandwich plate design directional valve elements B8_58… are very compact direct operated solenoid valves which control the start, the direction and the leak free stop the oil fl ow. These elements basically consist of a stackable housing (1) with a control spool (2), one solenoid (5), a spring holder plug (7); two return springs (4); a solenoid screw-in cartridge VEI (8) with its coil (9).

When energized, the force of the solenoid (5) pushes the control spool (2) from its rest position “0” to the end position “b”. If there is a solenoid cartridge VEI (8) type C, A, O, the oil fl ow goes direct-ly to the port A; if there is a solenoid cartridge VEI (8) type D (Dual locking), it is necessary the energize the solenoid cartridge as well in order to allow the oil fl ow to the port A.

Once the solenoid (5) is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool (2) returns in its rest position. The leak free holding at port A is provided by energizing (or de-energizing, if the VEI is NC type) the solenoid cartridge.

By energizing (or de-energizing) the VEI (8) to an open position, the A port is open to tank and downstream fl ow is possible.

The coils are fastened to the respective solenoids (5) and VEI (8) by the ring nuts (6) and (10).

The sandwich plate design directional valve elements B8080… are compact direct operated proportional solenoid valves which control the start, the stop, the direction and the quantity of the oil fl ow. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4).

Energized by an electronic feed regulator, each solenoid (5) displaces the control spool (2) from its neutral-central position “0” proportionally to the current received, in open loop mode; a regu-

lated oil fl ow P to A , or P to B, is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool (2) returns in its neutral-central position “0”.

Each coil is fastened to the solenoid tube (5) by a ring nut (6). A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

The sandwich plate design directional valve elements L8_10… are compact direct operated solenoid valves which control the start, the stop and the direction of the oil fl ow. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4).

When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position “0” to the required end position “a” or “b”, and the required fl ow from P to A (with B to T),

or P to B (with A to T) is achieved. Once the solenoid is de-ener-gized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position.

The sandwich plate design directional valve elements L8011… are compact direct operated solenoid valves which control the start, the stop and the direction of the oil fl ow, with the option to adjust the spool switching time. These elements basically consist of a stackable housing (1) with a control spool (2), one or two solenoids (5), and one or two return springs (4).

The spring chambers are connected to the tank port through orifi ces. When energized, the spool (2) travels and oil is pushed to tank from one of the spring chambers: if the cross section of the orifi ces changes, the switching time changes as well. Three orifi ce sizes are available: smaller orifi ce diameter results in longer

switching time, even though the actual time is dependent upon pressure, fl ow and viscosity.

When energized, the force of the solenoid (5) pushes the control spool (2) from its neutral-central position to the required end posi-tion, and the required fl ow from P to A (with B to T), or P to B (with A to T) is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (3) back against the housing and the spool returns in its neutral-central position.

The performance range has been established by employing a 0.3 mm orifi ce. The performance range is wider with larger orifi ces.

The performance curves are measured with fl ow going across and coming back, like P > A and B > T. With “lever type” emer-gency control, the performance limits are slightly lower.

The sandwich plate design valve elements L808003P… are compact direct operated proportional solenoid valves which divert totally or partially the inlet P fl ow to Tank.

These elements basically consist of a stackable housing (1) with a control spool (2), one solenoid (3), and one return spring (4).

With the solenoid de-energized, the return spring (4) keeps the spool (2) in its rest position “0” and all the inlet P fl ow passes through the valve and is unloaded to Tank. When energized by the electronic feed regulator, the solenoid (3) displaces the control

spool (2) from its rest position proportionally to the current recei-ved and proportionally restricts the fl ow area to Tank. A regulated, non pressure compensated, oil fl ow is diverted from P to T and the remaining amount of inlet fl ow in the P line remains available for the downstream operators.

The coil (3) is fastened to the solenoid tube by a ring nut (5). A pin (6) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

The sandwich plate design elements L808003C… are 3 way proportional pressure compensated direct solenoid operated valves. They control the inlet (P) fl ow and allow through (out of P1) only the fl ow required by the downstream operators; the excess oil, pressurized at working pressure, is diverted from the inlet P line to Tank. The combination of the proportional regulator with the unloading compensator guarantees stable and constant fl ow, independently from the working pressure.

The proportional control is achieved by a wet pin proportional screwed-in tube, with extractable coil which is energized by an external electronic feed regulator; the electronic regulator performs an “open loop” control of the current supplied to the coil.

These elements basically consist of a stackable housing (1) with a control spool (2), a solenoid (3), and one return spring (4); additio-nally there is a compensator (6), with a preset spring (7), a spring retainer plug (8) and a drain orifi ce (9). A coil (5) is held to the solenoid tube by the ring nut (10).

With the solenoid de-energized, the spool stays in the closed position; the pressure overcomes the compensator spring (7) and the inlet (P) oil is unloaded to Tank at the p value shown by the characteristic curve. Pressure at (P1) is drained to Tank through the orifi ce and drops to zero.

By energizing the solenoid (3) through the electronic feed regulator, the control spool (2) is displaced from its rest position proportio-nally to the current; the corresponding opening allows a pressure compensated fl ow to proceed to P1, while the excess fl ow is diverted to Tank.

With the solenoid (3) de-energized, the return spring (4) pushes the spool (2) to its rest position “0” fully closed. No fl ow goes to P1 and any residual pressure at P1 is drained through the orifi ce. The compensator (6) is pushed fully open all the oil is unloaded to Tank.

Energized by an electronic feed regulator, each solenoid (3) displaces the control spool (2) from its neutral-central position “0”

proportionally to the current received; a regulated oil fl ow P to A , or P to B, is achieved. Once the solenoid is de-energized, the return spring (4) pushes the spool thrust washer (5) back against the housing and the spool returns in its neutral-central position.

Each coil (3) is fastened to the solenoid tube by a ring nut (6). A pin (7) allows to push the spool (2) in emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

The sandwich plate design directional valve elements L8_1… are compact manual operated valves which control the start, the stop and the direction of the oil fl ow.

These elements basically consist of a stackable housing (1) with a control spool (2), a block with the control lever (3), and a spring housing (4) with a return spring (5).

The hand operated lever moves the control spool (2) from its neutral-central position “0” to the required position “a” or “b”, and the required fl ow from P to A (with B to T), or P to B (with A to T) is achieved.

Type L8_L1_2S_ __M100 is the valve version in which the return spring (5) brings the spool back to neutral-central position “0” when the manual lever is not operated.

The valve is available with a choice of spool variants (refer to page 3).

Type L8_L1_2S_ __F100 is the valve version with mechanical detent in which the control spool (2) stays in anyone of the 3 achieved positions “0”, “a” or “b” when the lever is left free. With this valve, the oil delivery can continue without any action on the lever.

Also this version is available with a choice of spool variants (refer to page 3).

Special types of control are available upon request.

Principles of Operation, Cross Section

The sandwich plate design directional valve elements L8510… are compact direct operated pressure compensated solenoid valves which control the start, the stop, the direction and the quantity of the oil fl ow, with a FLOW SHARING principle. These elements basically consist of a stackable housing (1) with a control spool, two solenoids (4), two return springs. When energized, each sole-noid (4) displaces the control spool from its neutral-central position “0” and the metering notches are open; fl ow is delivered to the 3 way pressure compensator followed by a check valve for each port A and B. The compensator, balanced by the LS pressure at the opposite end, lifts up and unloads a pressure compensated fl ow which is sent to the A (or B) port through the relevant check valve; at the same time the opposite port allows oil return to tank.

LS pressure reaches the compensator “dead end” directly from the A or B port, while the check valves lock eventual pressure oscilla-tions which could affect the compensator function.

When the solenoid is de-energized, the return spring pushes the spool thrust washer back against the housing and the spool returns in its neutral-central position.

Each coil (4) is fastened to the solenoid tube by a ring nut (7). A pin allows to push the spool under emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

Adjusting Options

The sandwich plate design directional valve elements L8511… are compact direct operated pressure compensated solenoid valves which control the start, the stop, the direction and the quantity of the oil fl ow, with a FLOW SHARING principle. These elements basically consist of a stackable housing (1) with a control spool, two solenoids (4), two return springs. When energized, each sole-noid (4) displaces the control spool from its neutral-central position “0” and the metering notches are open; fl ow is delivered to the 3 way pressure compensator followed by a check valve for each port A and B. The compensator, balanced by the LS pressure at the opposite end, lifts up and unloads a pressure compensated fl ow which is sent to the A (or B) port through the relevant check valve; at the same time the opposite port allows oil return to tank.



Each coil (4) is fastened to the solenoid tube by a ring nut (7). A pin allows to push the spool under emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

Principles of Operation, Cross Section

The sandwich plate design directional valve elements L8580… are compact direct operated pressure compensated proportional solenoid valves which control the start, the stop, the direction and the quantity of the oil fl ow, with a FLOW SHARING principle. These elements basically consist of a stackable housing (1) with a control spool, two solenoids (4), two return springs. Energized by an electronic feed regulator, each solenoid (4) displaces the control spool from its neutral-central position “0” proportionally to the current received. When the spool is shifted and the metering notch is open, fl ow delivery starts and is controlled by a 3 way pressure compensator followed by a check valve for each port A and B. The compensator, balanced by the LS pressure at the opposite end, lifts up and unloads a regulated fl ow which is sent to the A (or B) port through the relevant check valve; at the same time the oppo-site port allows oil return to tank.



Each coil (4) is fastened to the solenoid tube by the ring nut (7). A pin allows to push the spool under emergency conditions, when the solenoid cannot be energized, like in case of voltage shortage.

Description

The sandwich plate design directional valve elements TI-C2-__-… basically consist of a stackable housing with a 2 way compensator controlled by the LS pressure signal. The normally open compensator maintains a constant pres-sure difference between the P1 (outlet) line and the LS pressure; the result is a constant oil fl ow to the P1 port for the downstream operators, independently from the working pressure.

The excess oil must be unloaded to tank through a relief valve.

The stackable housing is made of Yellow Zinc plated (Cr+3) Cast Iron.

Description

The intermediate plate with an auxiliary hand pump has to be insert between the inlet plate and the ED modular directional valves. It necessary to use an interme-diate plate with a hand pump (EPM) when for directive or technical motivations it needs to generate a pressure without the use of any other energy source. Handling the lever the spool is moved and by two relieves, it transfers a fl ow rate of oil from T line to P line. This hand pump is declared: double effect hand pump, because the fl ow is transferred whether pulling whether pushing the lever. When the pump is not used, the lever is positioned in the opening phase end-run.

It is available, on request, a longer lever. In this way the operator force to move the lever is lower.

Description

The secondary fl angeable elements EDM-PO-__ can be interfaced and bolted on top of the A and B ports of the ED elements of the Directional Valve Assembly.

They incorporate two Cross Piloted Check Valves which allow free fl ow toward the A and B outlet ports, and lock in a leak free mode the fl ow returning from the actuator, until suffi cient pilot pressure is built up in the opposite line and the check valve is opened.

Depending on the version selected (AB, or 0A, or 0B), the PO Check Valve is in both A and B ports, or in A port only, or in B port only (see hydraulic symbols).The Pilot Ratio is 4:1, consequently, the pilot pressure needs to be at least 1/4, or 25% of the load induced pressure in the actuator before the Check Valve opens, and oil can return to tank.

− Hydraulic port sizes: A and B – SAE 8. − Special coating and plating available, C.F.

Stacking Modules – Counterbalance

EDM-CB

1/2

Description

The secondary fl angeable elements EDM-CB-__ can be interfaced and bolted on top of the A and B ports of the ED elements of the Directional Valve Assembly.

They incorporate one or two Cross Piloted Counterbalance Valves which allow free fl ow toward the A and B outlet ports, and lock in a leak free mode the fl ow returning from the actuator. Pilot pressure in the opposite line reduces the pres-sure setting of the counterbalance valve in proportion to the pilot ratio until open-ing and allowing the fl ow return from the actuator.

The pressure setting should be at least 1.3 times the highest expected load.Depending on the version selected, the counterbalance function can be double-acting or single-acting in both A and B ports, or in A port only, or in B port only (see hydraulic symbols).

− Port sizes: A and B – SAE 8.

Flangeable elements with single or double secondary pressure relief valves and anti-cavitation function

EDCM/EDCMF-VM

1/4

Description

These modular secondary elements can be fl ange mounted on top of the EDC elements machined with the interfacing surface.

They let through free fl ow to the A (or B) port until pressure increases and reach-es the selected pressure setting; then they release fl ow into the Tank channels.

The direct acting relief cartridges are designed for quick response and stable pressure control; they also incorporate a reverse fl ow check for anti-cavitation.

With a body made of zinc plated cast iron, these elements combine secondary pressure relief and dual cross-over, with anti-cavitation function.

Description

These secondary fl angeable elements can be interfaced and bolted on top of the A and B ports of the ED elements of the directional valve assembly.

They incorporate two cross piloted check valve which allow free fl ow toward the A and B outlet ports, and lock in a leak free mode the fl ow returning from the actuator, until suffi cient pilot pressure is built up in the opposite line and the check valve in opened.

Depending on the version selected (AB, or 0A, or 0B), the PO check valve is in both A and B ports, or in A port only, or in B port only (see hydraulic symbols).

The pilot ratio in 3:1, consequently, the pilot pressure needs to be at least 1/3, or 33% of the load induced pressure in the actuator before Check Valve opens, and oil can return to tank.

The body of these elements in made of Yellow Zinc Plated (Cr+3) Cast Iron (CI). Hydraulic Ports A2 and B2 are size G3/8 or G1/2 or 3/4-16 UNF 2-B (SAE8).

Description

Initially, fl ow passes freely from 2 to 1. When the pressure at 1 exceeds the pres-sure setting, the valve acts to restrict input fl ow at 2. This increases the pres-sure drop through the valve and maintains consistent pressure at 1. The spring chamber is drained at 3 to prevent a build-up of back-pressure against the spool. Additionally, if pressure at 1 rises above the pressure setting, fl ow is relieved to 3 until the setting is re-attained.

A constant fl ow rate, regardless of system pressures, is established from 1 to 3 while a minimum pressure differential of 14 bar (200 psi) exists between the two ports. Input fl ow supplied to 1 in excess of the regulated output at 3 is by-passed to 2. The valve cannot be adjusted for variable fl ow output. Flow from 3 to 1 is limited by the diameter of the selected control orifi ce and is not pressure compen-sated. Flow from 2 to 1 is not permitted.

Description

A constant fl ow rate, regardless of system pressures, is established from 1 to 3 while a minimum pressure differential of 14 bar (200 psi) exists between the two ports. Input fl ow supplied to 1 in excess of the regulated output at 3 is by-passed to 2. Output fl ow can be varied from closed to the nominal maximum rating for the valve. Flow from 2 to 1 is not permitted.

Description

When pressure at 2 rises above the spring bias pressure, the check seat is pushed away from the piston and fl ow is allowed from 2 to 1. When load pressure at 1 rises above the pressure setting (turn counterclockwise to increase setting – turn clockwise to decrease setting), the direct-acting, relief function is activated and fl ow is relieved from 1 to 2. With pilot pressure at 3, the pressure setting is reduced in proportion to the stated ratio of the valve, until fully open with free-fl ow from 1 to 2. The spring chamber is drained to 2, and any back-pressure at 2 is additive to the pressure setting in all functions.

When load pressure at 1 rises above the pressure setting (turn counterclockwise to increase setting - turn clockwise to decrease setting), the direct-acting, differential area relief function is activated and fl ow is relieved from 1 to 2. With pilot pressure at 3, the pressure setting is reduced in proportion to the stated ratio of the valve, until fully open with free-fl ow from 1 to 2. The valve applies a balanced piston design allowing relief operation at the valve setting independent of back-pressure at 2. However, the piloted opening of the valve remains subject to additive pressure at port 2.
