Easytork Vane Actuator (“EVA”)

Only One Moving Piece – Pure Rotary-to-Rotary Movement

Internal Air Path

All air path is internal, no external piping necessary in double-acting or fail-safe.

Environmental Air Never Enters

In fail-safe, solenoid still operates on double-acting principle. No environment air ever enters actuator through vacuum associated with springs.

Rugged Actuator: Key Actuator Features

Easytork offers a 2 year or 2 million cycle warranty. The Easytork Vane Actuator is more economical, smaller, lighter, and more durable than a rack & pinion.

Eliminate Springs – Using Air Reservoir as Spring Replacement

Air reservoirs are commonly used to fail-safe large mission critical valves that would otherwise be too big with springs. Springs are wearable parts; on the other hand, air reservoir avoids spring issues developed over time including: spring fatigue, spring drift, and/or one or more unnoticed broken springs in a spring nest.

Pressure Free Symmetrical Shaft and Bushings

No downward “pistoning” force and accompanying friction as commonly seen with other designs.

The Economics of Spring“less”

Since EVAs do not push against springs, users can use a smaller actuator body to achieve the same fail-safe end of stroke torque requirement. With springs, actuators generate about 30%+ the torque of what the original double-acting body can produce, while the EVA generates 60%+.

Convert Actuator to FS or DA Convert Actuator to FC or FO Manual Override / Gear Box Equivalent

Easy Travel Limit Change

The standard travel stop adjustment is +/-5° per stopper bolt, for a total of +/- 10°.

Heavy Duty DU Bushings

Results in a supported vane shaft and life long lubrication.

Reduces Inventory Considerations By At Least 4x

Safely and quickly change functionality by manipulating how air flows within the actuator. While other actuator packages require different packages for different functions, one EVA has all functions built in.

EVAs have one moving part that creates pure rotary-to-rotary movement. Rack & pinions convert linear-to-rotary movement. The fewer moving parts there are, the fewer potential sources of failure, and the better the lifespan.

Non-O-Ring Sealing

O-rings are meant for static sealing and not for dynamic sealing. Yet, most brands use O-rings for direct sealing which result in problems such as high friction, high break away torque, and high wear and tear.

Double Lip-Seal

With increased air pressure, pressure pushes against double lip-seal allowing for greater tightness against housing body. Lip-sealing aligns and provides tightness under pressure.

Lightweight Integral Vane-Shaft

The core of the vane-shaft is light weight. This reduces the vane’s impact to the stopper bolts and prolongs cycle life.

Lifelong Lubrication

Advanced non-hydrocarbon based grease delivers wide temperature range and long-term lubrication without requiring maintenance. In non-high cycle applications (slower than 150 seconds per stroke), the lubrication of the actuator is not necessary, allowing for the use of oil-free compressed air. Environment not polluted by exhaust of actuator.

No Stick-Slip, 4 PSI For Full Stroke

Vane has limited contact to housing body which results in low friction, smooth operation, and no “stick-slip”. Ideal for both on-off and precision modulating controls. Without load, the break away torque is under 4 psi for a full stroke.

No Air Pressure on Shaft

The lip-seal seals the housing as well as the shaft. Shaft does not experience air pressure.

Metal-to-Metal Contact

Stopper bolt does not impact vane sealing but against stainless steel vane assembly extrusion.

Triple ISO Flange Pattern

Easytork has triple ISO mounting pad. Therefore, as long as the valve has ISO top works, it will fit directly to the EVA in most cases. The EVA’s circular design offers 2 plus 1 ISO top work by turning the ISO mounting pad 45° without misaligning the valve and actuator. VDI / VDE3845 compatible even with a 45° shift.

Taper: Contact, Guiding and Support Area in Yellow:

Torque transfer area. The EVA vane-shaft and lower and upper shafts use Morse Tapered principle similar to that of a drill press. Machined taper surface binds together with connect bolt to tighten and support the shafts from side load.

Torque transfer area. The precision broach octagon shape hollow middle shaft allows the lower and upper shafts to be indexed at every 45° intervals.

No Valve Stem Leakage – Direct Mounting In All Situations

EVA’s valve stem engagement is 100% concentric, guided and supported which prevents valve stem leakage and prolongs the cycle life in all direct mount configurations. Typically, the engagement between the valve stem and the actuator is a major contributor to stem side loading and valve stem leakage. This problem is magnified with a bracket and coupler and orientation of valve/actuator assembly during cycling.

Direct Mount Drive Inserts

All actuators are fitted with adaptable drive inserts in order to accommodate different valve stem profiles. This enables valve stem to be an integral part of the actuator drive and eliminates the need for independent stem coupler for direct mount actuation. Drive insert is held in place by a s.s. circlip and has tight tolerance to prevent hysteresis and wear and tear.

Most Compact and Lightest Actuator

Easytork’s physical size and air consumption are significantly less than those of a comparable single-acting rack & pinion. For fail-safe requirement, users often have to size up rack & pinion as the spring return actuator only retains 30%+ of its original double-acting torque configuration. EVA fail-safe configuration retains 60%+ of its double-acting torque configuration.

EVA Double-Acting Principle and Sizing

10

Principle of Double-Acting Version

Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.

Torque Calculation

As Easytork’s vane is a pear shape, torque is calculated as such:

� Area A does not generate any force, the positive area is negated by the negative area.

� Area B and C have the same surface area.

� X is the distance from the pivot point to where area B and C are divided.

� Torque = (Force on B + C) * X - force lost for friction.

� X is constant so torque is linear.

� In a rectangular vane, the length of B = C. Easytork’s pear shape allows for length B > C thereby extending the effective lever arm. This makes the air consumption and air reservoir more efficient.

Sizing Double-Acting Version

The suggested safety factor for the double-acting version in normal working conditions is 15-20%. Actuator is designed to continuously operate no less than 15% to 20% of specified air pressure.

Sizing Examples for Double-Acting Version

Published valve torque = 600 in-lb

Safety factor = 600 in-lb + 20% = 720 in-lb

Air supply pressure available = 80 psi

The double-acting EVA actuator that produces a minimum of 720 in-lb at 80 psi is the EVA-0514 (double-acting torque output at 80 psi = 763 in-lb).

See torque output chart for published double-acting torque output.

EVA Fail-Safe Principle and Sizing

11

Principle of Fail-Safe Version

EVA utilizes an internal air reservoir to assure valve closure. When there is air failure, the pressurized air stored in the air reservoir is released and diluted with the vane chamber. After the vane chamber and air reservoir have been fully diluted, the remaining pressure in the actuator is synonymous with the end-of-stroke minimum torque, which can be calculated using Boyle’s Law (p2v2 = p1v1). The air reservoir chamber to vane chamber volume ratio is approximately 2.6 : 1 for all EVA models.

Sizing Fail-Safe Version

The suggested safety factor for fail-safe version in normal working conditions is 15-20%. Actuator is designed to continuously operate no less than 15% to 20% of specified air pressure.

There is no need to account for spring decay or other spring issues developed over time. EVA always retains 60%+ regardless of service duration.

Sizing Examples for Fail-Safe Version

Published valve torque = 800 in-lb

Safety factor = 800 in-lb + 20% = 960 in-lb

Air supply pressure available = 80 psi

The fail-safe EVA model that produces a minimum of 960 in-lb at 80 psi is the EVA-0717 (minimum fail-safe torque output at 80 psi = 992 in-lb).

See torque output chart for published minimum fail-safe torque output.

Assumptions for Boyle’s Law p2v2=p1v1

p1 = Pressure in reservoir 5.5 bar

v1 = Volume in reservoir 2.6

p2 = Pressure in vane + reservoir X

v2 = Volume in vane + reservoir 1 + 2.6 = 3.6

Absolute atmospheric pressure 1 bar

Calculation for p2 Remaining air pressure in system

after complete dilution =

minimum end-of stroke torque

p2v2 = p1v1 Boyle’s law

p2 = p1v1/v2

p2+1 = (p1+1)*v1/v2 +1 bar to account atmospheric pressure

p2 = (p1+1)*v1/v2 - 1

p2 = (5.5+1)*2.6/3.6 - 1

p2 = 3.69 barp2 / p1 = 67% Without friction, EVA fail-safe retains 67%

of double-acting torque. With friction, EVA fail-safe retains 60+% of double-acting torque

Gearbox Equivalent: Manual Override Without Air Supply

19

Wrench Manual Override

With no springs acting against the EVA, users can use a wrench on the actuator to manual override the valve. The operating torque against the wrench is the valve’s torque. The integral shaft/vane arrangement ensures shaft torque transfer without creating the side loading.

Procedures for Wrench Manual Override

For EVA-0717 and smaller

1. Block main air supply through slide valve.

2. While using a wrench to rotate the upper shaft of the actuator, engage the air relief valve to bleed actuator, item sold separately.

2a. Easytork also offers a built-in wrench system and air fill & relief valve female adaptor. It can be fixed on a bracket or onto the actuator for quick access.

2b. Air fill & relief valve female adaptor can be unscrewed from wrench and used to engage air relief valve for easy wrench manual operation.

ESV Manual Override Operation and Recharge

For EVA-1022 and larger

For larger actuators, when wrench manual override is not practical, users can skip the wrench operation and charge air to air reservoir to manual override the valve thru ESV.

1. Ensure ESV is setup on double-acting mode.

2. Ensure ESV is de-energized before using the manual override.

3. Charge air to air reservoir through built-in 2 liters air cylinder. Air cylinder chargeable to max. 200 bar (2,900 psi) with fixed 5.5 bar (80 psi) output pressure).

4. Use the screw driver to conduct the manual override from the ESV.

Control Valve Options

Perfect Movement: No Hysteresis, No Eccentricity

The EVA is ideal for modulating. With an integral vane-shaft construction (tapered engagement of the upper, vane, and lower shaft), pure rotary-to-rotary vane movement, and a hysteresis-free lower shaft, Easytork offers 100% repeatability and is hysteresis-free and eccentric-free from the positioner all the way to the valve stem.

Universal Positioner Plate

Easytork’s patented positioner plate (“ERPP”) provides for a universal interface for all positioners to the EVA for fail-safe applications. ERPP is available in standard or chemical resistant version with wide temp range from -40°C to 120°C (-40°F to 248°F). In fail-safe, environment air never enters ERPP through vacuum associated with spring-return actuators. A pressure sensor connects the ERPP to the positioner. When there is a disruption to the main air supply, the pressure sensor will de-energize the positioner.

Pure Rotary-to-Rotary, No Hysteresis

EVA’s movement is hysteresis-free rotary-to-rotary. Typical rack & pinion uses linear-to-rotary movement, and there is no way to avoid the fundamental hysteresis between the racks and the pinion.

One Integral Moving Piece

The tapered engagement of the upper, vane, and lower shaft allows the vane-shaft to have zero eccentricity and combines the parts into one integral piece.

ERPP Universal Interface

For fail-safe, ERPP allows any positioner to be installed with the EVA. For double-acting, ERPP is not required, users can directly pipe to port 2 and port 4 of actuator.

Close Mounting

Easytork can custom spline cut the stainless steel vane shaft to justify control valves with extended spline valve stems. The extended valve stem can engage, and pass directly through the vane shaft resulting in a significantly more compact package. Other benefits include better weight balance, high level throttling capabilities, and is ideal for high vibration applications.

180°°°° Operation

One System for Multiple Setups

EVA’s 180° system can be configured to two-position setup or three-position setup. Either setup can be configured to double-acting or fail-safe in any position (fail at 0°, 90°, or 180° for three-position setup, alternatively fail at 0° or 180° for two-position setup). With easy stroke adjustment on the actuators, 180° setup can be for 120°, 135° or 150° two-position application. Available in standard version or chemical resistant version.

Benefits include:

� Significantly lower cost due to EVA 180° system’s simple mechanical movement. This eliminates the need for a positioner or elaborate limit switch setup to control stoppage at the 90° position.

� Easytork system is the only 180° system in the market to have manual override in all situations (gearbox equivalent).

Three Position Setup (0°°°°, 90°°°°, 180°°°°) & Operation

Setup below shows adaptation with two EPVs.

Torque Output

180° operation for two-position or three-position has same output torque as an individual actuator output. Refer to EVA torque output page.

EVA Chemical Version

26

PTFE Coating

The EVA chemical version is designed to provide maximum protection in aggressive and corrosive environments. PTFE coating provides an armored layer of protection against a wide range of acids, caustics, alkalis, solvents and salt-laden (coastal refining, offshore & desalinations) environments.

PTFE Treated Housing

(Inside and Outside of Housing)

(All Internal Threads and Cavities)

The aluminum body is treated with a thermosetting tripolymer resin coating system formulated for mechanical components requiring corrosion resistance.

Stainless Steel Parts

The internal vane, upper and lower shafts, inserts and all connecting bolts are stainless steel.


In fail-safe, solenoid still operates on double-acting principle. No environment air ever enters actuator or solenoid valve through vacuum associated with springs.

Standard Version:

Aluminum: Epoxy Coating

Chemical Resistant Version:

Aluminum: PTFE Coating

General properties A rugged epoxy coating creates a barrier against many

chemicals. Epoxy coating will resist more acidic or basic

environments.

PTFE coating offers full surface coverage and exhibits

excellent corrosion resistance properties in a wide variety of

applications.

Performance limitations The general corrosion resistance is good, particularly in salt

or alkaline environments. There is limited resistance to

acids. Suitable for low concentrations of caustic washdown

solutions.

PTFE coating offers resistance to any environment where an

actuator would be installed. Given the integrity of the

surface, this coating can resist a broad array of chemical

environments at temperatures ranging from subzero to over

300° F.

Description

In a standard setup, QEP is connected to both QEVs, and redirects pressure air from air reservoir to pressure connection 2 (ccw) and pressure connection 4 (cw). The two QEVs are mounted directly on both sides of the vane chamber, and allow quick supply and exhaust air flow rate without passing back through the ESV or EPV.

Quick Exhaust Valve

27

A fast-acting kit comprises of one Quick Exhaust Plate (“QEP”) and two Quick Exhaust Valves (“QEV”). Together, they allow for quick open and close, ideal for emergency shut-down systems. The fast-acting kit redirects air to an external tubing’s larger orifice, and bypasses the EVA, ESV and EPV’s smaller orifice, before directly feeding the vane chamber.

Fast-acting maintains all the benefits of EVA and ESV combination, such as double-acting, fail-safe, manual override, and others.

For sizes EVA-0514 and larger. Not available in chemical resistant version.

Easytork Air Pilot Valve (“EPV”)

EVA can be fitted with the EPV, which is similar to a 5/2 air pilot valve. This setup allows the EVA to operate only with or without air supply. Requires only one main air supply for this setup.

EPV can be connected to any remotely mounted 3/2 solenoid valve (panel, built or attached to limit switch box conduit), this allows users to achieve fail-safe function without using the ESV.

EPV is available in standard or chemical resistant version with all silicone seals to allow wide temperature range. In fail-safe, environment air never enters EPV through vacuum associated with spring-return actuators.


� Without air supply� With air supply


Step-by-step:

1. The supply air delivered through port 1 is simultaneously channeled to through hole “B” which compresses spool spring, and through the internal check valve.

2. Supply air is channeled to through hole “D” after passing through the internal check valve.

3. Through hole “D” is connected to the spool valve chamber which directs air to either port 2 or port 4. Simultaneously, supply air from through hole “D” passes through port “C” which charges the air reservoir.

Without air supply:

� The spool spring is not compressed. Through hole “B” does not compress against spool spring, switching the pilot “Off”.

� The air reservoir maintains its pressure (check valve). Air from reservoir flows into the EPV via port “C” and through hole “D” (connected with spool valve chamber), turning actuator to fail-safe position.

With air supply:

� The spool spring is compressed. Through hole “B” compresses against spool spring, switching the pilot “On”.

� After passing through check valve, air supply from port 1 flows through hole “D” (connected with spool valve chamber), turning actuator to open position.

Note (1): If required, consult factory for minimum pressure setting for over 2 bar (30 psi).

Easytork Solenoid Valve (“ESV”)

Easytork recommends the ESV for interface with the EVA. The ESV directly controls the actuator to be either double-acting or fail-safe (fail-close or fail-open) without needing external piping. NAMUR interface allows another solenoid valve in the market to be installed, but external pilot and air pipings are required for fail-safe.

The ESV is fundamentally no different than other spool type solenoid valves except for additional drilling.

Manual override available when there is no electricity and/or no supply air.

ESV is available in standard or chemical resistant version, in either standard temp. or low temp. version. In fail-safe, environment air never enters ESV through vacuum associated with spring-return actuators.

1. The supply air delivered through port 1 is simultaneously channeled through the internal check valve and through hole “B”.

2. Supply air is channeled to through hole “D” after passing through the internal check valve.

3. Through hole “D” is connected with the spool valve and functions like a regular solenoid valve. Simultaneously, supply air from through hole “D” passes through port “C” which charges the air reservoir.

Basic Design Overview

The ESV redirects the spool valve’s main supply air from port 1 to through hole “D”. The ESV expands upon a typical spool solenoid valve design by drilling two through holes in the body of the solenoid valve (“B” and “D”) and drilling one additional port (“C”) to interface the actuator’s air reservoir. Through hole “D” is connected to the spool valve chamber.

Step-by-Step

Configuration Overview – Double-Acting or Fail-Safe

By rotating the switch on the ESV, users can alter the source to the air pilot within the solenoid valve. One option is for the air pilot source to be from the main supply air port “1”, the other option is through the air reservoir port “C”.

Double-Acting Configuration Fail-Safe Configuration

Air failure only (with electricity):

� The solenoid air pilot does not sense discontinued air supply via through hole “D” (connected to air reservoir, which will always have air). Solenoid valve is still “On”. No position change.

Electrical failure only (with air supply):

� Armature returns to original position switching the solenoid “Off”.

Manual override:

� Manual override available in electrical and/or air failure.

Air failure only (with electricity):

� The solenoid air pilot senses discontinued air supply via through hole “B” switching the solenoid “Off”.

� The air reservoir maintains its pressure (check valve). Air from reservoir flows into the solenoid valve via port “C” and through hole “D” turning actuator to fail-safe position.

Electrical failure only (with air supply):

� Armature returns to original position switching the solenoid “Off”. No output torque decay.

Manual override:

� Manual override available in electrical and/or air failure.

Interchangeable Coils

Standard, Ex-Proof and ATEX EX coil type utilizes the same ESV body, so coils are interchangeable. Easytork offers the flexibility of purchasing the valve body and coils separately to minimize inventory. No spacer required for any degree of coil mounting (0°, 90°, 180°, or 270°).

Products Certified To

CSA - (C22.2 and UL STD 429).

Factory Mutual - Explosion Proof Environments.

ATEX - Explosion Proof Environments.

CE - EMF and Low Voltage Directives.

ESV is a four-way, two-position (5/2) valve. There are two pressure ports, two exhaust ports, and a common air supply port. In addition to standard 5/2 valve, ESV has one air reservoir ports.

Wide Temperature Range

Low temperature coil with silicone based seals are available for operation at -40°C (-40°F).

Low Power Operators

Low power operators are available to 0.7 watts (30mm version) and 1.1 watts (22mm version). 24 VDC voltage with 2.0 watts is standard for standard type coil.

Manual Override in All Situations

Detent-style manual override screw to "lock-and-hold" the valve in open or close position upon power outage. The normal position for the switch is "0". A 90° rotation of the switch in the counter clockwise direction to "I" will manually override the solenoid and lock the solenoid in the disengaged position until the switch is returned to its original position.

In the event of air failure, de-energize the coil and select the valve to 5/2 double-acting mode to manually override the valve.

Sediment Free Tapered Lip-Seal

ESV utilizes bi-directional tapered lip-seal that wipes air line sediment and keeps spool surface clean. This design also eliminates sticking problems and avoids spiral twist.

No Solenoid Burnout

Air pilot is internally supplied when air pressure is from 2 to 10 bar (30 to 150 psi).

The coil is hermetically sealed.

Double-Acting / Fail-Safe Pilot

ESV can convert EVA between FS and DA functions with easy hand operated switch for two selectable internal air passages to solenoid pilot.

Switch Anti-Tampering Device

ESV design incorporates a lock to prevent third parties from accidentally changing the ESV’s functionality. In the event there is no main air supply and manual override is required, the lock can be switched back to double-acting to run manual override.

Easytork Mounting Bracket (“EMB”) and Fixture

Easytork supplies EMB and Mounting Bracket Fixture (“MBF”). The EMB is a loose piece, kit-based, mounting bracket that can be easily and precisely conjoined to create a mounting bracket with the appropriate specifications including height and mounting patterns.

Users can quickly and precisely weld loose EMB parts into an integral bracket through the MBF. MBF has accurate centerlines to allow loose EMBs of various mounting patterns to be welded together at any desired height. The conjoined EMB has perfect alignment.

EMB and EVA’s extended lower shaft direct mount to the valve stem. This creates stability, stiffness and perfect alignment between actuator and valve stem in all mounting positions. This avoids fugitive emission of the stem packing or malfunctioning of the valve.

Bracket Assembly Method

Users can quickly and precisely weld loose EMBs into an integral bracket through the MBF.
