Triac controls line of E Series electric actuators offers a broad range of torques from 300 to 30,000 in. lbs. and numerous features including manual overrides, auxiliary switches, 4-20mA modulating control , several voltage options including 1-phase 24/120V/220V - 12 and 24VDC, 3-phase 220v, 380v, and 440v ( view voltage chart ). The units feature EP-CYCLICAL gear trains and a unique manual override with handwheel. All actuators are NEMA 4x and are designed for maximum cycle life due to our rugged motors and gear trains. As with all Triac actuators, our E Series electrics are available with mounting kits on most ball, butterfly and plug valves. The actuators are ideal for use on butterfly and louver dampers with the increased benefit of self-locking EP-CYCLICAL gears, eliminating the need for unreliable solenoid brakes.
