Pneumatic Butterfly Valve Actuator

For a butterfly valve to start opening from a completely closed position, higher torque is required to overcome the friction between the seat and valve body. Lower torques are needed to keep the valve moving in the middle section of the valve stroke. Pneumatic butterfly valve actuator is an ideal device to meet this request with all required certifications, which is ideal product for butterfly valve use in various types of industries.

Customized Control System

The control system is an important element of the actuator, it can meet various actuator functional requirements.

Partial Stroke Test(PST)

PST is a very good safety measure that can set periodic partial stroke action tests to ensure the normal operation of the control valve.

Fire Protection System

In the ESD emergency shutdown system control, the use of low-temperature and easily fusible accessories can automatically reset the valve to a safe position according to the design requirements when a fire occurs.

1Sec Quick Cut-off

For some working conditions that require quick shutdown, Bigtork can meet the emergency shutdown requirements of user devices through special gas circuit design and unique module configuration.

Adaptive actuators and control schemes for harsh working conditions

BIGTORK can provide customized solutions and special products for some harsh working conditions, such as high temperature, high frequency, large opening and closing pressure difference, and easy locking, etc.
