4 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. Only One Moving Piece Pure Rotary-to-Rotary Movement 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. The Economics of Spring less Since EVAs do not push against springs, users can use a smaller actuator body to achieve the same failsafe 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%+. 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. Easytork Vane Actuator ( EVA ) Internal Air Path All air path is internal, no external piping necessary in double-acting or fail-safe. Prolongs Valve Life The EVA valve stem engagement is 100% concentric and prevents valve stem leakage to prolong the cycle life of the valve. Fast-Acting Larger air port for fast-acting. Pressure Free Symmetrical Shaft and Bushings No downward pistoning force and accompanying friction as commonly seen with other designs. Easy Travel Limit Change The standard travel stop adjustment is +/- 5 per stopper bolt, for a total of +/- 10. Patents: Pneumatic Actuator Structure USA = 8,671,672 Other countries pending Heavy Duty DU Bushings Results in a supported vane shaft and life long lubrication. Extend Cam Radius (Vane Shaft to Stopper) Results in 3-5 times lower impact force against stop bolts and associated shaft side loading. 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.

5 Rugged Actuator: Key Vane Features Easytork's patented actuator design improves on the reliability of vane actuators and simplifies vane s single-acting design so that it can economically replace rack & pinions. 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. Lifelong Lubrication Advanced non-hydrocarbon based grease delivers wide temperature range and long-term lubrication without requiring maintenance. In nonhigh cycle applications (slower than 150 seconds per stroke), the lubrication of the actuator is not necessary, allowing for the use of oilfree compressed air. Environment not polluted by exhaust of actuator. 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. Wide Temperature Range Silicone material is the standard material, it is fully bonded to the vane/shaft. EVA is suitable from -40 C to 120 C (-40 F to 248 F), covering everything from low to high temperature applications. Cartridge Vane Design allows for easy replacement and maintenance. 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. 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. 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.

6 Rugged Actuator: Key Interface Features Easytork simplifies control valve assembly by designing a single actuator that can easily interface the widest variety of valves. 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. Patents: Integral Unit & Zero Eccentricity China = , Taiwan = M445076, other countries pending Other = >0% eccentric Valve stem leakage Independent stem coupler Valve stem movement EVA = 0% eccentric No valve stem leakage Integral vane shafts 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. Precision Broach: Contact and Index Area in Blue: Torque transfer area. The precision broach octagon shape hollow middle shaft allows the lower and upper shafts to be indexed at every 45 intervals. 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. 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. Direct Mount Shafts Users can easily and quickly swap the upper / lower shaft for 1. direct mount shaft 2. semi-direct mount shaft 3. lockout & PST device 4. two valve operation 5. Other non-stock custom shapes such as damper drive.

7 Most Compact and Lightest Actuator A smaller, lighter actuator lowers both the initial cost of ownership and the total cost of ownership over the lifespan of the 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. Fail-Safe Size Comparison Rack & Pinion (2 Piston) Vane Rack & Pinion (4 Piston) Fail-Safe Weight 5.5 BAR (80 PSI) Weight (gram) per Nm Weight Comparison: >60% Less Than Single-Acting Rack & Pinions For the same output torque, Easytork weighs >60% less than a standard single-acting rack & pinion. 0.0 Easytork Rack & Pinion (2 Piston) Vane Rack & Pinion (4 Piston) Fail-Safe Air Consumption (CW + CCW) 5.5 BAR (80 PSI) 14.0 Air Volume (cm^3) per Nm Easytork Rack & Pinion (2 Piston) Vane Rack & Pinion (4 Piston) Air Usage: >25% Less Than Single-Acting Rack & Pinions For the same output torque, EVA uses >25% less air than a single-acting rack & pinion. Versus a comparable double-acting rack & pinion, EVA uses >50% less air. Note: All comparisons based on model sizes with equivalent fail-end-of-stroke output torques. 7

Easytork Air Pilot Valve Instead of a solenoid valve, the EVA can be fitted with a 5/2 air pilot valve. This setup will allow the EVA to operate only with or without air supply. Requires only one main air supply for this setup. With air supply Without air supply 9

10 EVA Double-Acting Principle and Sizing 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. Double-Acting Torque Output Torque 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 Rotation 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. 10

11 EVA Fail-Safe Principle and Sizing 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. Air 5.5 BAR (80 PSI) At 100% Torque No Air Supply ( 5.5 BAR) Close Beginning 100% of DA No Air Supply ( 3.69 BAR) Close End 67% of DA Volume Ratio (All Models) Vane chamber = 1 Air reservoir chamber = 2.6 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 = 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 bar p2 / p1 = 67% Without friction, EVA fail-safe retains 67% of double-acting torque. With friction, EVA fail-safe retains 60+% of double-acting torque % of Double-Acting Torque Fail-Safe Torque Output 100% 90% 80% 70% 60% 50% 40% 30% 20% 10% 0% Rotation EVA - Open / EVA - Close (full air supply, with or without electricity) EVA - Close (no air supply) 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. 11

20 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-torotary 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. 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 vaneshaft to have zero eccentricity and combines the parts into one integral piece. Pure rotary-to-rotary movement Integral unit & zero eccentricity Patents: Integral Unit & Zero Eccentricity China = , Taiwan = M445076, other countries pending 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. 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. Non-stock item, consult with Easytork. ERPP Universal Interface Custom Spline 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.

26 EVA Chemical Version 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. Environmental Air Never Enters PTFE Treated Housing (Inside and Outside of Housing) In fail-safe, solenoid still operates on double-acting principle. No environment air ever enters actuator or solenoid valve through vacuum associated with springs. (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. Standard Version: Aluminum: Epoxy Coating Chemical Resistant Version: Aluminum: PTFE Coating General properties Performance limitations A rugged epoxy coating creates a barrier against many chemicals. Epoxy coating will resist more acidic or basic environments. 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 full surface coverage and exhibits excellent corrosion resistance properties in a wide variety of applications. 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.

27 Fast-Acting 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. 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.

28 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. Easytork Air Pilot Valve Counter-Clockwise Clockwise Dimensions EPV With Remote Mounted 3/2 Solenoid Valve 3/2 Solenoid (I.e. other brand) With air supply Without air supply EPV Technical Specification Operating pressure (1) 2-10 bar ( psi) Operating medium Air (dry or lubricated) Flow l/min (Cv) Port size: 1/4" 1000 l/min (Cv = 1.0) Temperature range -40 C to 120 C (-40 F to 248 F) Note (1): If required, consult factory for minimum pressure setting for over 2 bar (30 psi). Basic Design Overview Note: Figures in drawings in mm. EPV Note: Refer to page 9 Remote Mounted Solenoid Valve (3/2) = Fail- Safe Principle for air flow diagram. 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. Connects to air reservoir 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. 5 C 4 B 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: D Internal check valve 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. 28

29 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 (failclose 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. 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. Connects to air reservoir Step-by-Step 1. The supply air delivered through port 1 is simultaneously channeled through the internal check valve and through hole B. 5 C 4 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. 3 D 2 1 Internal check valve 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 Solenoid air pilot Solenoid air pilot 5 3 C D 4 2 Patents: ESV B 1 Internal check valve CCW 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. 5 3 C D 4 2 CW B 1 Internal check valve 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.

30 Easytork Solenoid Valve Design Features 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. 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 ). 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. Anti-Tamper Device DA FS Manual Override in All Situations Detent-style manual override screw to "lockand-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. Versions ESV is available in standard or chemical resistant version, in either standard temp. or low temp. version. 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. Wide Temperature Range Low temperature coil with silicone based seals are available for operation at -40 C (-40 F). 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.
