Dwyer WE33 User Manual
Series WE33 3-Way Tri-Clamp Ball Valve
Specifications - Installation and Operating Instructions
odulating actuator accepts a 4 to 20
m
A input for valve positioning. Actuators
m
feature thermal overload protection and
permanently lubricated gear train.
he pneumatic double acting actuator
T
ses an air supply to drive the valve open
u
nd closed. The actuator has two supply
a
orts, with one driving the valve open
p
and the other driving the valve closed.
Spring return pneumatic actuators use
the air supply to open the valve, and
nternally loaded springs return the valve
i
o the closed position. Also available is
t
the SN solenoid valve to electrically
switch the air supply pressure between
the air supply ports for opening and
closing the valve. Actuators are
onstructed of anodized and epoxy
c
oated aluminum for years of corrosion
c
free service.

he Series WE33 incorporates a full port
T
-way tri-clamp SS ball valve for great
3
flow rates with minimal pressure drop.
The valve features a blowout-proof stem
for added safety, reinforced PTFE seats
nd seals for longer life, and a 316 SS

ASTM CF8M) ball for better
(
erformance. Actuators are direct
p
ounted creating a compact assembly
m
for tight spaces. Limit switches are able
to be mounted directly to the valves
allowing for remote position indication.
he Series WE33 can be configured with
T
either an electric or pneumatic actuator.
Electric actuators are available in
weatherproof or explosion-proof, a
variety of supply voltages and two-
osition or modulating control. Two-
p
osition actuators use the supply voltage
p
to drive the valve open or close, while the
