View ProductPart-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.
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.
Pneumatic actuator selection
Pneumatic actuators use compressed air to move a valve. For rack-and-pinion designs, piston movement drives a rotary output shaft. Selection depends on valve load and the air pressure available at the actuator.
- Air supply and torque
- Use the minimum available pressure at the actuator during movement. Ask for the output torque data for the selected arrangement, rather than choosing from the compressor pressure alone.
- Loss-of-air response
- Specify whether the valve should remain in position, open or close. Double-acting and spring-return arrangements behave differently; confirm the full actuator and control circuit.
- Accessories and interface
- Identify the need for a solenoid valve, position indication or positioner. Confirm air connections, mounting details, travel and the required opening and closing times.
Ratings, options and dimensions depend on the selected configuration. Confirm the final datasheet before ordering.
