El-O-Matic EL Electric Rotary Valve Actuators

EL Electric Rotary Valve Actuators
by El-O-Matic

EL Series Electric Rotary Valve Actuators produce up to 7,080 lb. in. of torque and utilize a miltiple reduction worm gear system that is self-locking and provides tight positioning control for quarter turn valves.

Specifically designed for challenging process automation where an air supply is not available, low ambien tempertures make air powered actuators unreliable, actuator locatin makes maintenance chores difficult, or an all-electric control system is desired.

EL Series Actuators offer a host of standard, integrated features including manual override, torque switches (except EL 20/55), dome position indicator, mechanical travel stops, and compartment heater (except EL 20). They also accept a wide range of control accessories and options.
