 Description/Overview
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.
All
EL Series Actuators are available in weatherproof/corrosion resistant (NEMA
4X) or explosionproof (NEMA4X/7/9) models (except EL 20).
