The W.E. Anderson Series ACT
Actuators are available in either
pneumatic or electric models. The wide
range of torques and voltages means
there is an actuator for almost any
application. The standard ISO 5211
mounting
configuration makes
installation to any valve or damper
quick 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
corrosion resistant anodized aluminum
body is designed to withstand the harsh
and 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
available in two-position or modulating
configurations 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
come standard with two auxiliary
switches, and modulating models offer
an output for position monitoring.
Certain models are equipped with
manual overrides allowing the operator
to cycle the valve manually for
installation or maintenance checks.
