Pneumation Butterfly Valve Supply & Manufacture
What is pneumation butterfly valve?
Pneumatic butterfly valve is an important control valve and plays a key role in the pipeline system.It is composed of a pneumatic actuator connected to a butterfly valve. The compressed air drives the actuator to drive the circular butterfly plate to rotate 90°, thereby realizing the switching and flow adjustment of the pipeline.
Pneumatic butterfly valve is a valve product with excellent performance and wide use, which can meet the fluid control needs in different scenarios.

Advantage of Wafer flange butterfly
Quick response: The pneumatic butterfly valve uses a pneumatic actuator to control the valve switch, which can quickly respond to the control signal to achieve rapid opening and closing of the valve, thereby quickly adjusting the fluid flow and pressure..
Saving space: The pneumatic butterfly valve is relatively small in size and compact in structure, which can save installation space and make it easier to install and maintain in a limited space.
Low pressure loss: The internal structure of the valve body of the pneumatic butterfly valve is simple, and the resistance when the fluid flows through is small, thus reducing the pressure loss of the pipeline system.
Good adjustability: The pneumatic butterfly valve can adjust the valve opening by adjusting the pressure of the air source, thereby accurately controlling the flow of the medium.It has a large adjustment range and high adjustment accuracy, and can meet the flow control requirements of different processes.
Butterfly valve with pneumatic actuator working
The initial position of the valve is determined according to actual needs. When the valve rotates 90° from the initial position, one action ends (from open to closed, or from closed to open), otherwise, the other action (from closed to open, or from open to closed) ends.
The execution speed of pneumatic butterfly valve is relatively fast, it is not easy to be damaged due to jamming during movement, and it does not require workers’ hands. It can not only be used as a stop valve, but can also be equipped with a valve positioner to regulate and control the pipeline medium.
Pneumatic butterfly valve actuators are divided into single-acting and double-acting forms. The double action is exhaust opening and exhaust closing! Among them, the single-acting actuator has a spring return function, which can automatically close or open when the air or power is cut off, with a high safety factor!
