El-O-Matic EL 1200, 2500 Series Electric Rotary Valve Actuators

EL 1200, 2500 Series Electric Rotary
Valve Actuators by El-O-Matic

Specifically designed and engineered for marine and wastewater applications, EL 1200 and 2500 Series Actuators produce 10,580 and 22,125 lb. in. torque, and are ideal for use with butterfly and larger type valves.

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.

  • 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)
