Series
WE33
3-Way Tri-Clamp Stainless Steel Ball Valve
Cavity Filled, Electric and Pneumatic Actuators
he pneumatic double acting actuator uses
T
n air supply t o drive the valve open and
a
losed. The actuator has two supply ports,
c with one driving the valve open and the other driving the valve closed. Spring return pneumatic actuators use the air
upply to open the valve, and internally
s
oaded springs return the valve to the
l
losed position. Also available is the SN
c
olenoid valve to electrically switch the air
s supply pressure between the air supply ports for opening and closing the valve. Actuators are constructed of anodized and
poxy coated aluminum for years of
e
orrosion free service.

he Series WE33 incorporates a full port
T
-way tri-clamp SS ball valve for great flow
3
ates with minimal pressure drop. The
r
alve features a blowout-proof stem for
ctuators are direct mounted creating a
A
ompact assembly for tight spaces. Limit
c
witches are able to be mounted directly to
s the valves allowing for remote position indication. The Ser ies WE33 can be configured with either an electric or pneumatic actuator.
lectric actuators are available in
E
eatherproof or explosion-proof, a variety
w
f supply voltages and two-position or
o modulating control. Two-position actuators use the supply volt age to drive the valve open or close, while the modulating actuator accepts a 4 to 20 mA input for
alve positioning. Actuators feature
hermal overload protection and
t
ermanently lubricated gear train.
