Pneumatic forging steel ball valve is ball valve with pneumatic actuator. Pneumatic actuators to perform relatively fast speed, the fastest switching speed/time, 0.05 seconds so usually also called pneumatic quick to cut off the ball. Pneumatic forging steel ball valves are usually with various accessories, such as solenoid valve, air source treatment sanlian pieces, limit switch, locator, control box, etc., in order to realize the local control and remote centralized control, in the control room can control the switch of the valve, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety.

Pneumatic forging steel ball valve is ball valve with pneumatic actuator, pneumatic actuator of execution speed relatively quickly, without the need for artificial themselves open to close, have made a very big rise in industrial automation. Pneumatic forging steel ball valve only need gas rotate for 90 degrees operation and small rotational torque can be closed tightly. Full equality of the valve body cavity for medium resistance is very small, straight flow channel. Usually do think most suitable direct ball valve open and close, but recent development has put a ball valve designed to make it with throttling and control flow. Ball valve itself is the main characteristics of compact structure, easy operation and maintenance, and is applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Pneumatic forging steel ball valve body can be as a whole, also can be combined.

The working principle of pneumatic forging steel ball valve is to rely on rotary valve core to keep the valve open or closed. Pneumatic ball valve switch lightweight, small size, can make a large caliber, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, pneumatic forging steel ball valve has been widely used in various industries.

Pneumatic forging steel ball valve is compressed air as power source, the cylinder as actuator, and by means of electric valve positioner, converters, solenoid valve, a valve to drive the valve such as attachment, realize the switch quantity or proportion type adjustment, industrial automation control system receives the control signal to complete conditioning pipeline medium: flow, pressure, temperature and other process parameters. Pneumatic control valve is to control the characteristics of simple, quick response, and intrinsically safe, do not need another explosion protection measures.

Pneumatic forging steel ball valve in the line is mainly used for cutting speed is quick, distribution, and change the flow direction of medium. Pneumatic ball valve is widely used in recent years a new type of valve, it has the following advantages:

1. The fluid resistance is small, its resistance coefficient with section of equal length.

2. Simple structure, small volume, light weight.

3. Compact and reliable, the ball valve sealing surface material widely used carbon fiber, PPL, sealed performance is good, have been widely used in the vacuum system.

4. Easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

5. Easy maintenance, pneumatic ball valve has simple structure, sealing ring, which generally remove replacement is more convenient.

6. In the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, medium through, can not cause the valve sealing surface erosion.
