Series WE08 2-Piece NPT Brass Ball Valve
Specications - Installation and Operating Instructions
WE08-EDA02-AA05
WE08-EDA02 WE08-ETD01-A
The Series WE08 2-Piece NPT Brass Ball Valve incorporates a full port 2-piece
brass ball valve for great ow 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 brass ball for better performance. Actuators are direct mounted creating a
compact assembly for tight spaces.
The Series WE08 can be congured 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 4-20 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.
Also, 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
WARNING
valves may change position if power fails or is removed. Never insert any object or
body part into the valve body. Severe injury may occur.
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
completely disassembled.
When working on the Actuator/Valve assembly, disconnect the
air or power supply to the actuator. Spring return actuators/
Before beginning disassembly, ensure that the air supply to the
actuator has been disconnected, all accessories have been

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
insufcient.
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 Denition
“Duty Cycle” means the starting frequency.
Formula: Running Time ÷ (Running Time + Rest Time) x 100% = duty cycle
–> 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 –> The rest time will be 35 seconds
75% duty cycle 15 x [(1 - 75%) / 75%] = 5 –> The rest time will be 5 seconds
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
WARNING
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 specications 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 specications 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.
1. DO NOT under any circumstances remove the cover of the
actuator while in a hazardous location. Removal of the cover
