T
he W.E. Anderson Series ACT
A
ctuators are available in either
p
neumatic or electric models. The wide
r
ange of torques and voltages means
there is an actuator for almost any
application. The standard ISO 5211
mounting configuration makes
i
nstallation to any valve or damper
q
uick and simple.
W
.E. Anderson pneumatic ACT models
are a compact rack-and-pinion design
with a symmetrical structure that
ensures fast and steady action, high
precision and high output power. The
c
orrosion resistant anodized aluminum
b
ody is designed to withstand the harsh
a
nd abusive industrial environments
and provide reliable service. We offer
double acting and spring return models
in a variety of sizes to fit any
application.
W
.E. Anderson electric ACT models are
a
vailable in two-position or modulating
c
onfigurations and NEMA 4X or NEMA
7
rated enclosures. All electric
actuators utilize a high grade powder
coated aluminum enclosure with visual
indicators. The two-position models
c
ome standard with two auxiliary
s
witches, and modulating models offer
a
n output for position monitoring.
C
ertain models are equipped with
manual overrides allowing the operator
to cycle the valve manually for
installation or maintenance checks.
