Relational Guide
How do I choose the right actuator for my valve?
The right actuator should be selected based on the valve type, movement, required torque or thrust, power source, control requirements, and operating conditions.
- Quarter-turn valves (such as ball and butterfly valves) usually use rotary actuators.
- Gate and globe valves may require multi-turn or linear actuators.
- The actuator output must match the valve’s torque or thrust requirements.
What is the difference between pneumatic and electric valve actuators?
Pneumatic actuators use compressed air to operate valves and are known for fast response, reliable operation, and suitability for frequent automated cycles.
Electric actuators use electric motors and are ideal for applications requiring precise control, remote operation, or where compressed air is unavailable.
How do I determine the correct actuator size and torque?
Actuator sizing should be based on the valve’s actual operating torque or thrust, not only the valve size.
The selection should consider:
- Valve type and size
- Operating pressure
- Media characteristics
- Operating conditions
- Required safety margin
Can one actuator be used for different types of valves?
Not always. Actuator selection depends on the valve’s movement type, mounting connection, and torque or thrust requirements.
Typical matching includes:
- Ball & Butterfly Valves: Quarter-turn actuators
- Gate Valves: Multi-turn actuators
- Globe Valves: Linear or suitable multi-turn actuators
What information do I need to provide when ordering a valve actuator?
To recommend the right actuator and provide an accurate quotation, please provide:
- Valve type and model
- Valve size and pressure rating
- Required torque or thrust
- Operation mode (On/Off or Modulating)
- Power supply or air supply
- Operating temperature
- Required accessories and control requirements
