Series WE20 Buttery Valve

Specications - Installation and Operating Instructions

WE20-ETD04-LE-A

WE20-EDA06-LE WE20-CDA04-WP-AA07

The SERIES WE20 is offered in lug or wafer body styles and is equipped with a

PTFE or EPDM liner. The most critical aspect of the Series WE20 Buttery Valves is the cartridge seat design, which alleviates installation problems associated with common “dove tail design” seats. Valve torques are lower and more consistent as the seat dynamics are not dependent on being coupled between two anges. Precision

machining of the disc and body allow the cartridge design to maintain a tighter disc to

seat tolerance, providing a perfect low torque seal each and every time the valve is cycled. The seat to disc seal is independent of ange support and capable of full rated dead end service.

Actuators are directly mounted creating a compact assembly for tight spaces. Limit

switches are able to be mounted directly to the valves allowing for remote position

indication.

The Series WE20 can be congured with either an electric or pneumatic actuator. Electric actuators are available in weatherproof or explosion-proof, a variety of supply voltages and two-position or modulating control. Two-position actuators use the supply voltage to drive the valve open or closed, while the modulating actuator accepts a 4 to 20 mA input for valve positioning. Actuators feature thermal overload protection and

permanently lubricated gear train. The pneumatic double acting actuator uses an air

supply to drive the valve open and closed. The actuator has two supply ports, with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve, and internally loaded springs return the valve to the closed position.

The pneumatic double acting actuator uses an air supply to drive the valve open and closed. The actuator has two supply ports with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air supply to open the valve and internally loaded springs return the valve to the closed position. Also available is the SV3 solenoid valve to electrically switch the air supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and epoxy coated aluminum for years of corrosion free service.

PNEUMATIC ACTUATOR Note: For optimal operation, pneumatic actuators should be run with a supply of

clean, lubricated air.

Spring Return Actuator Operation

Air to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Loss of air to PORT 2 causes air to exhaust and the actuator turns clockwise

(CW). This is the FAIL CLOSE operation.

Double Acting Actuators Operation

Air to PORT 2 (the left hand port) causes the actuator to turn counterclockwise (CCW). Air to PORT 1 (the right hand port) causes the actuator to turn clockwise

(CW).

Pneumatic Actuator Maintenance

Routine maintenance of pneumatic actuator:

• Keep the air supply dry and clean

• Keep the actuator surface clean and free from dust

• Periodic checks should be done to make sure all ttings are tight

• Pneumatic actuators are supplied with lubrication to last the entire life span of the actuator under normal operating conditions.

The outer surface of the pneumatic actuator should be clean to avoid friction or corrosion. All ttings and connections should be tight to prevent leaks during operation. Check the bolts mounting the valve to the actuator to make sure they have not come loose during shipping or installation. Make sure the valve and

actuator are not rubbing or jamming against other components during operation.

The actuator should be inspected annually to make sure all ttings and bolts are

tight and nothing has come loose during operation.

Disassembling Pneumatic Actuators

WARNING

removed, and that the actuator has been disassembled from the valve.

1. Loosen the end cap fasteners (23) with a wrench (size varies depending on actuator model). On the spring return actuator, alternate 3 to 5 turns on each fastener until the springs are completely decompressed. Use caution when removing the cap since the springs are under load until the fasteners are fully extended.

2. Remove the pinion snap ring (13) with a lock ring tool. The indicator (12) may now be removed.

3. Turn the pinion shaft (2) counter clockwise until the pistons are at the full end of travel. Disengage the pistons (15) from the pinion. (Note: Low pressure air--3 to 5 psi MAXIMUM--might be required to force the pistons completely from the body.) Note the position of the pistons before removing them from the actuator body.

4. Remove the pinion through the bottom of the actuator. The actuator is now

Reassembling Pneumatic Actuators

WARNING

1. Apply a light lm of grease to all O-rings and the pinion before replacing.

2. Put the pinion (2) back through the actuator with the ats of the pinion shaft

running parallel with the body.

3. When reassembling the actuator, make sure that the piston racks are square

to the actuator body and returned to their original orientation. (Note: The normal operation of all spring return pneumatic actuators is FAIL CLOSED. To change the

orientation to FAIL OPEN, rotate the racks 180º to create a reverse operation.

4. When replacing springs in a spring return actuator, ensure that the springs are replaced in their identical position in the end cap from which they were removed. (Note: In some circumstances, you might want to change the standard 80 pound spring set to t your application and available air pressure.

5. Seal the end caps with a petroleum lubricant and bolt to actuator body.

6. Check the seal of the actuator by covering seal areas (pinion, end caps) with

soapy water and using low pressure air to the actuator to ensure that no bubbles are produced.

1. Check the solenoid valve. Is the

coil burnt out or is the solenoid spool?

2. The actuator will not move

because of debris in the gears.

3. The pneumatic line to the

actuator is distorted or smashed.

4. The pneumatic line is frozen

because of low temperatures and moisture.

1. The air supply pressure is

insufcient.

2. Are other pneumatic devices

consuming the air required for the actuator to operate?

3. The pneumatic actuator is

undersized for the application.

Be sure the actuator surfaces are free of debris and scratches before reassembling.

1. Replace the solenoid

valve coil or remove debris.

2. Disassemble the actuator, clean the debris and reassemble the actuator.

3. Replace pneumatic line to

the actuator.

4. Warm the pneumatic lines and remove moisture from

supply lines.

1. Increase the air supply

pressure and look for leaks

in the supply pressure pipeline.

2. Increase the air supply or reduce the number of

devices operating at the

same time.

3. Replace the actuator with

a larger actuator.

ELECTRIC ACTUATORS Electric Installation

1. Operate valve manually and place in the open position.

2. Remove any mechanical stops the valve might have. (DO NOT REMOVE ANY PARTS NECESSARY FOR THE PROPER OPERATION OF THE VALVE, SUCH AS THE PACKING GLAND, PACKING NUT, ETC.)

3. Ensure that the actuator output shaft and valve stem are aligned properly. If they are not, operate the valve manually until they are correct.

4. Remove actuator cover.

5. Bring power to the actuator. CAUTION: Make sure power is OFF at the main box.

6. Wire the actuator per the diagram attached to the inside of the cover. Special actuators (those with positioner boards, etc.) will have diagrams enclosed inside the cover.

7. Securely tighten bolts used to mount the actuator to a mounting bracket or directly to the valve mounting pad if it is ISO5211 compliant.

8. Cycle the unit several times and check the open and closed positions of the valve. Cams are pre-adjusted at the factory; due to the variety of valve designs and types however, slight adjustments might be required.

9. Replace cover and tighten screws.

To Set The Closed Position

1. Apply power to terminals to move the valve toward the closed position. The

bottom cam and switch control the closed position. In the closed position, the set screw in the bottom cam will be accessible.

2. If the valve is not closed completely:

A. Slightly loosen the set screw on the bottom cam.

B. Rotate the cam counterclockwise (CCW) by hand until the switch makes contact. Contact is made when a slight click can be heard. By making incremental CCW movements of the bottom cam, the valve can be positioned precisely in the

desired position. C. When the top cam is set, tighten the set screw securely.

3. If the valve closes too far: A. Apply power to terminals. This will begin to rotate valve CCW. When valve is fully closed and in the exact position desired, remove power from actuator.

B. Loosen the set screw in the top cam.

C. Rotate the top cam clockwise (CW) until the switch arm drops off the round portion of the cam onto the at section. A slight click can be heard as the switch is no longer making contact with the round part of the cam. D. Continue applying power to terminals until valve is in the desired position.

Note: To speed up installation of the control wires to the ACT-MDXX modulating actuator, it is recommended to remove the control module from the actuator. The control module can be removed by removing the two mounting screws on the left

and right of the control module. Install the control wires to the correct terminal points and then reinstall the control module.

Electric Actuator Maintenance

Once the actuator has been properly installed, it requires no maintenance. The gear

train has been lubricated and in most cases will never be opened.

Duty Cycle Denition

“Duty Cycle” means the starting frequency.

Formula: Running Time

–

> Rest Time = Running Time x (1 - duty cycle) ÷ duty cycle

For example: The running time is 15 seconds 30% duty cycle 15 x [(1 - 30%) / 30%] = 35 75% duty cycle 15 x [(1 - 75%) / 75%] = 5

L

N

If the duty cycle is higher, the rest time will be shortened, which means the starting frequency will be higher.

Thermal Overload

All actuators are equipped with thermal overload protection to guard the motor against damage due to overheating.

Mechanical Overload

All actuators are designed to withstand stall conditions. It is not recommended to subject the unit to repeated stall conditions.

Explosion-Proof Electric Actuators

÷ (Running Time + Rest Time) x 100% = duty cycle

> The rest time will be 35 seconds

2. DO NOT under any circumstances use an explosion-proof electric actuator in a hazardous location that does not meet the specications for which the actuator was

designed.

3. Always verify that all electrical circuits are de-energized before opening the

actuator.

4. Always mount and cycle test the actuator on the valve in a non-hazardous

location.

5. When removing the cover, care must be taken not to scratch, scar of deform the ame path of the cover and base of the actuator, since this will negate the NEMA

rating of the enclosure.

6. When replacing the cover, take care that the gasket is in place to assure proper clearance after the cover is secured.

7. All electrical connections must be in accordance with the specications for which

the unit is being used.

8. Should the unit ever require maintenance, remove from the hazardous location before attempting to work on the unit. If the actuator is in a critical application, it is advisable to have a standby unit in stock.
