Part-Turn Electric Actuators

Part-turn electric actuator selection

Part-turn actuators provide rotary travel for valves such as ball and butterfly valves. Match the required travel and output torque before considering the electrical and control options.

Valve load

Use the valve torque for the actual pressure, temperature and operating conditions. Check starting, running and seating loads, together with the valve’s allowable torque.

Travel and mounting

Provide the travel angle, mounting pattern, shaft dimensions and clearance for installation and manual operation.

Control and duty

Define isolation or modulating duty, operating time, movement frequency, supply voltage and required command and feedback signals.
