The Series WE02 incorporates a full
port 3-piece SS ball valve for great flow
rates with minimal pressure drop. The
valve features a blowout proof stem for
added safety, reinforced PTFE seats
and seals for longer life, and a 316 SS
(ASTM CF8M) ball for better
performance. Actuators are direct
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 WE02 can be configured
with either an electric or pneumatic
actuator. Electric actuators are available
in weatherproof or explosion-proof, a
variety of supply voltages and twoposition or modulating control. Twoposition actuators use the supply
voltage to drive the valve open or close,
while the modulating actuator accepts a

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.

outine maintenance of pneumatic actuator:
R
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 fittings are tight
• Pneumatic actuators are supplied with lubrication to last the entire life span of the
actuator under normal operating conditions.
he outer surface of the pneumatic actuator should be clean to avoid friction or
T
orrosion. All fittings and connections should be tight to prevent leaks during
c
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 fittings and bolts are
ight and nothing has come loose during operation.

emoved, and that the actuator has been disassembled from the valve.
r
1. Loosen the end cap fasteners (22) 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 (10) with a lock ring tool. The indicator (7) 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 (11) 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
completely disassembled.

WARNING
1. Apply a light film of grease to all O-rings and the pinion before replacing.
. Put the pinion (2) back through the actuator with the flats of the pinion shaft
2
unning parallel with the body.
r
. When reassembling the actuator, make sure that the piston racks are square to
3
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 fit 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. 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 Open Position
1. Cycle the valve to the open position by applying power to terminals. The top cam
and switch control this position. In the open position, the set screw in the top cam
will be accessible.
2. If the valve is not open completely:
A. Slightly loosen the set screw on the top cam.
B. Rotate the cam clockwise (CW) by hand until the switch makes contact.
Contact is made when a slight click can be heard. By making incremental CW
movements of the top 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 opens too far:
A. Apply power to terminals. This will begin to rotate valve CW. When
valve is fully open and in the exact position desired, remove power from actuator.
B. Loosen the set screw in the top cam.
C. Rotate the top cam counterclockwise (CCW) until the switch arm drops off the
round portion of the cam onto the flat section. A slight click can be heard as the
switch changes state.
D. Continue applying power to terminals until valve is in the desired position.
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 counter-clockwise (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 flat 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.

Duty Cycle Definition
“Duty Cycle” means the starting frequency.
Fomula: Running Time (Running Time Rest Time) x 100% = duty cycle
est Time = Running Time x (1 - duty cycle) duty cycle
R
or example: The running time is 15 seconds
F
•
•
•
•
•
•
30% duty cycle 15 x [(1 - 30%) / 30%] = 35 The rest time will be 35 seconds
75% duty cycle 15 x [(1 - 75%) / 75%] = 5 The rest time will be 5 seconds
If the duty cycle is higher, the rest time will be shortened. It means the starting
requency will be higher.

WARNING
Explosion-Proof Electric Actuators
. DO NOT under any circumstances remove the cover of the
1
ctuator while in a hazardous location. Removal of the cover
a
while in a hazardous location could cause ignition of hazardous atmospheres.
2. DO NOT under any circumstances use an explosion-proof electric actuator in a
hazardous location that does not meet the specifications 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
flame 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 specifications 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.
