Quarter-turn electric actuators

September 2003 Valves, Actuators & Pump Control Security Services & Risk Management

The Series ELQ XP electric actuators are powerful, ¼-turn units with five sizes covering the torque range from 100 to 800 Nm. They incorporate high ratio drive (HRD) gearing which provides a compact backlash free reduction gear, suitable for both tight positional control and long trouble free ON/OFF operation. Universal power control allows direct connection to all the usual voltages. The explosion proof housing contains the motor, gear reduction and the electronic control unit (ECU).

Electronic control enables precise control of the actuators internal functions and a ready interface to a wide range of control options. Electronic torque control is included as a standard feature. Modular construction is used throughout and allows for a wide range of 'kit' and 'factory' options. The manual override hand wheel is constantly engaged, it is non-rotating and arranged so that at no time can be back-driven by the motor. The hand wheel is equipped with a spinner and so can be easily removed. The mounting/drive is certified to ISO 5211.
