Series WE34 3-Way Flanged Stainless Steel Ball Valve
Specifications - Installation and Operating Instructions
he modulating actuator accepts a 4 to 20
t
A input for valve positioning. Actuators
m
eature thermal overload protection and
f
ermanently lubricated gear train.
p
The pneumatic double acting actuator
uses an air supply to drive the valve open
nd closed. The actuator has two supply
a
orts, with one driving the valve open
p
nd the other driving the valve closed.
a
pring return pneumatic actuators use
S
the air supply to open the valve, and
internally loaded springs return the valve
to the closed position. Also available is
he SN solenoid valve to electrically
t
witch the air supply pressure between
s
he air supply ports for opening and
t
losing the valve. Actuators are
c
constructed of anodized and epoxy
coated aluminum for years of corrosion
free service.
