Dwyer WE03 - Manual

Series WE03 3-Piece Tri-Clamp Stainless Steel Ball Valve
Specifications - Installation and Operating Instructions
Bulletin V-WE03
TM
The Series WE03 incorporates a full port
3-piece tri-clamp 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 WE03 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 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. 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.
