SERVICE MANUALVSD05M Solenoid Actuated

Directional Control Valves

“A” Design Series

CAUTION – Before performing any serviceoperation on any Directional Control Valve,be sure that all pressure has been relievedfrom BOTH SIDES of the system.

CAUTION – Before performing any serviceoperation on any Directional Control Valve,disconnect or lock off power supply.

CAUTION – Before manually actuating anyDirectional Control Valve, be sure that anyresulting machine function will not endangerpersons or equipment.

PRODUCT IDENTIFICATIONEach Directional Control Valve has an Ordering Codeprinted on its cover label. See Figure 1 for thelocation of the Ordering Code.

This Service Booklet applies to products with OrderingCodes like the sample in Figure 2 below.

GENERAL SPECIFICATIONSRECOMMENDED FLUIDPetroleum, water-based fluids (not more than 40%water) and most phosphate esters. Other fluids maybe acceptable, but special O-rings may be required.Viton seals standard.

FLUID TEMPERATURE RANGEFluid temperature up to 200° F. (93° C.) will notappreciably affect valve performance. However, forsafety reasons, temperatures above 130° F. (54° C.)are not recommended.

RECOMMENDED OPERATING VISCOSITY80 to 350 SUS (16 to 70 CS).

FILTRATIONISO 18/16/13 or better.

MOUNTING POSITIONAny unrestricted position acceptable. Horizontalmounting preferred.

NFPA FLOW PATH/ACTUATING PATTERNSOLENOID, AIR AND OIL ACTUATED:

Actuating operator a - connects flow to cylinder portA.

Actuating operator b - connects flow to cylinder portB.

NOTE: NFPA flow path/actuating pattern is reversedfor spool code “L”.

GENERAL INFORMATIONSOLENOID ACTUATED – Spring centered and springoffset valve types will be spring positioned unlessactuated continuously. Detented, no-spring valvesmay be actuated momentarily. When solenoid is notactuated, the spool will remain in last positionattained, provided there is no severe shock, vibrationor pressure surge.

Pressure surges in a common tank line serving theseand other valves can be great enough to causeinadvertent valve shifting. This is particularly criticalin the no-spring, detented type valves. Separate tanklines may be necessary.

NOTE: Any sliding spool valve held shifted underpressure for long periods may stick and not springreturn due to fluid residue formation. To preventsticking, valves should be cycled periodically.

PREVENTIVE MAINTENANCEAfter Directional Control Valves have been put inoperation, provide periodic inspection andmaintenance. The check points listed below willassist you in extending the life of your Continentalvalves.

Fluid Operating Temperature – Fluid temperature atthe reservoir during operation should be kept between100° F. and 130° F. (37° C. and 54° C.).

Fluid Cleanliness – Control particle contamination bychanging or cleaning all filter elements periodicallyBEFORE they become clogged and start to by-pass.

Electrical Inspection – Periodically check to assureproper voltage, and that all electrical connections aremaking good contact.

After Extended Shutdowns – Some types ofhydraulic fluids become tacky after long periods ofnon-use. Manually actuate valves several times afterextended shutdowns to assure that all componentsmove freely before powering up.

CAUTION – Before manually actuating anyDirectional Control Valve, be sure that anyresulting machine function will not endangerpersons or equipment.

VSD05M VALVE REPAIR PROCEDURESDISASSEMBLY and REASSEMBLYGENERALDisassembly and reassembly of Directional ControlValves is a delicate operation. Anyone attempting itmust assume responsibility for the operation of thevalve. Continental valves may be returned to thefactory or to an Authorized Repair Center for repair.Contact your local Distributor or ContinentalHydraulics for details.

If interchanging spool types or making otherconversions, restamp the escutcheon plate to show

the correct code. Include stops, spool, spring, anddetent orientation. See Figure 2 to serve as a guideto correct numbering.

Disassembly in the field by other than an AuthorizedRepair Center technician, whether for repair ormodification may void warranty.

Before disassembly, study the exploded view belowand note the orientation and location of all parts.Note that the spring retainers are used only in theassemblies that are spring centered. Special careshould be taken to avoid damage to the spool and/orbody bore. Even a microscopic nick in a land on thespool or body may ruin the valve.

All valves can be disassembled and reassembled in ahorizontal-mounted position, provided there isadequate space and the work area is clean.

Place the spool in a bath of clean oil to coat it with aprotective film, and ease assembly. Inspect o-ringsfor nicks, and make sure they are well oiled. It’s agood idea to replace all seals whenever the valve isdisassembled.

Continental valves are precisely machined to exactingtolerances. Do not force any parts, or overtightenthreaded fasteners.

TROUBLESHOOTING GUIDE

PROBLEM POSSIBLE SOLUTION

Erratic or binding valve spools. Drain and flush the system. Disassemble valve and check spool and plug assemblies for burrs or other damage. Replace parts as necessary.

New valve does not function. Improper installation. See page 1 for valve flow path/actuating patterns.Check electric connections and circuit breakers. Confirm that hydraulic fluid type and viscosity meet specifications given on page 1.

Overhauled valve does not function. Improper reassembly or reinstallation. See page 2 for reassemblyinformation. See page 1 for valve flow path/actuating patterns. Confirm that hydraulic fluid type and viscosity meet specifications given on page 1.

Valve leakage. Check for leaking seals. Replace as needed.

Repeated solenoid burnout. Check voltage to determine that it is within ±10% of rating. See page 3. Check that opposing solenoids are not being energized simultaneously.

Detent spool does not shift properly. Check that solenoid is energized long enough to ensure complete shift.

Cylinder controlled by valve won’t Confirm that there is no internal leakage in the cylinder, and that there hold its load. are no fluid leaks in the power system. If no other sources of leakage

are found, disassemble valve and check for wear or scoring on body bore and spool. Replace defective parts.
