Pneumatic/Electric/Gear/Lever operated Butterfly Valve

Actuators of Butterfly Valve

Every butterfly valve requires a force device, and the actuator is the device that provides the force required to operate the valve manually or automatically.

Common actuators used in butterfly valves:

1. Handle actuator:

the most commonly used manual operation of small diameter butterfly valves. Suitable for butterfly valves with DN≤250.

2. Worm gear actuator:

It can reduce the torque through speed ratio and is suitable for manual operation of any caliber.

3. Pneumatic actuator:

Using compressed air to operate the valve, the butterfly valve can be opened and closed quickly.

4. Electric actuator:

Uses electricity to operate the valve. Suitable for applications requiring precise control or requiring automation and remote operation.
