FAQ

Q: What are the main types of valve actuators?

A: The main types are pneumatic, electric, and hydraulic actuators.

Q: How do I choose the right actuator?

A: Selection depends on valve type, torque requirement, control mode, and working conditions.

Q: What is the difference between pneumatic and electric actuators?

A: Pneumatic actuators offer fast response and reliability, while electric actuators provide higher precision and easier automation.

Q: What is torque in a valve actuator?

A: Torque refers to the rotational force required to operate a valve, especially for quarter-turn valves.

Q: Can one actuator fit all valve types?

A: No. Actuators must be matched with specific valve types and sizes for proper operation.

Q: Do you provide complete actuator assemblies?

A: Yes. We supply actuators with valves, positioners, and accessories as complete packages.
