Actuated Plastic Butterfly Valves

Electric Series 94 on Type-57P Butterfly Valve

Butterfly valves up to 4" can be actuated with the Series 94 electric actuator. The Series 94 actuator is a basic electric actuator designed for smaller quarter-turn valves, and is a good low-cost alternative to larger electric actuators. The Series 94 actuators have a thermally protected, bi-directional, capacitor run motor with a permanently lubricated gear train. Because of their size, the Series 94 actuators have a short open/close time, approximately 5 seconds, and a weight of only 3.5 lbs.
