Dwyer WE02 - Manual

Series WE02 3-Piece Stainless Steel Ball Valve
Specifications - Installation and Operating Instructions
Bulletin V-WE02
TM
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 two-
position or modulating control. Two-
position actuators use the supply
voltage to drive the valve open or close,
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.
Also available is the SN 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.
