Multi-Turn Electric Actuators

Multi-turn electric actuator selection

Multi-turn actuation delivers more than one output revolution. A gate or globe valve may require both rotational input and control of axial stem load, so the complete drive arrangement matters.

Torque, thrust and travel

Provide the valve’s torque or thrust data, total travel and number of output turns. State the stem arrangement and any gearbox or thrust-unit requirements.

Speed and duty

Relate the required opening time to output speed and total turns. Include starts per hour and the intended isolation or positioning duty.

Installation and controls

Check stem clearance, mounting dimensions, power supply, local controls and remote feedback. Request the correct torque- and travel-setting procedure for the selected assembly.
