SERIES ACT PNEUMATIC AND ELECTRIC ACTUATORS

Actuators for Valve and Damper Automation

The W.E. Anderson Series ACTActuators are available in eitherpneumatic or electric models. The widerange of torques and voltages means thereis an actuator for almost any application.The standard ISO 5211 mountingconfiguration makes installation to anyvalve or damper quick and simple.W.E. Anderson pneumatic ACT models area compact rack-and-pinion design with asymmetrical structure that ensures fast andsteady action, high precision and highoutput power. The corrosion resistantanodized aluminum body is designed towithstand the harsh and abusive industrialenvironments and provide reliable service.We offer double acting and spring returnmodels in a variety of sizes to fit anyapplication.

W.E. Anderson electric ACT models areavailable in two-position or modulatingconfigurations and NEMA 4X or NEMA 7rated enclosures. All electric actuatorsutilize a high grade powder coatedaluminum enclosure with visual indicators. The two-position models come standardwith two auxiliary switches, and the modulatingmodels offer an output for positionmonitoring. Certain models are equippedwith manual overrides allowing theoperator to cycle the valve manually forinstallation or maintenance checks.
