EA20 Series Valve Actuators. Working in conjunction with primary loop controllers, these low torque non-spring return actuators will proportionally position fuel valves, butterfly valves, dampers or other similar devices.



The output shaft moves in both directions and can stop at any point in the stroke. The hardened steel crankshaft is driven through a train of precision hobbed gears sealed in oil. This reliable actuator is driven by a shaded pole motor completely submerged in oil and sealed in an aluminum case, minimizing maintenance.

Four models are available featuring a standard 100ž internal feedback slidewire and a selection of travel time and rotation limit. Not available with end limit switches, some models have auxiliary switches and a variety of optional features. The EA-20 Series are UL and cUL or CSA listed, except for models with built-in transformers. CSA listed models are: EA21-00003-000-0-00, EA22-00000-000-0-00 and EA24-00000-000-0-00. It is compatible with the VB-7000- and VB-9000 valves in this catalog.
