A self-locking worm gear drive system, lubed-for-life gear case, rugged, purpose-build full ball bearing motor, anti-condensation heater, precision adjustable limit switch cams, hermetically enclosed mechanical position indicator, declutchable manual override, and NEMA 4, 4X, 7 and 9 housings combine to provide an all encompassing actuator that provides precise on/off valve positioning service, extra long life, very low maintenance, and maximum corrosion resistance. 

All EL 1200 and 2500 Series Actuators are also available with a full line of integrated automation, environmental, and control accessories. 
 
 

Features Torque Outputs - EL 1200 - 10, 580 lb. in.; EL 2500 - 22,125 lb. in. Aut-O-Ride Declutchable Lever Manual Override - allows manual release of gear train to permit valve operaion even with fused motor and automatically returns to "remote" electrical operation when motor is energized.  Permits use of field - replaceable, large spoked handwheel for reduced operator effort and complete safety. (EL 1200 and 2500) Reg-U-Tork Electromechanical Torque Regulatro/Limiter - serves to protect valve from damage in the egent foreign material (debris) should foul the valve seat, and acts as a "torque regulator" to provide a reserve of torque up to the rated maximum. (EL 1200 and EL 2500) Integral Motor Centrifugal Switch - effectively removes the starting capacitor from the circuit once the motor reaches full pseed and returns capacitor to the circuit when the motor stops. (EL 2400 only) NEMA 6 (Submersible) Rating - permits use in 20 feet of seatwater for 24 hours.  (Optional EL 1200 and 2500)
