Pneumatic ball valves

Pneumatic ball valve is also called ball valve with pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast, and the fastest switching speed is 0.05 seconds/time, so it is usually called a pneumatic quick cut-off ball valve. Pneumatic ball valves are classified into two-way pneumatic ball valves, pneumatic 3 way ball valve, and four-way pneumatic ball valves according to the number of branches.

The working principle of the pneumatic ball valve is to make the valve unblocked or blocked by rotating the valve core. Pneumatic ball valve switch is light, small size, can be made into large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often closed, not easy to be eroded by medium, and are widely used in various industries.Common pneumatic ball valves are VT Series Pneumatic Actuator, VSP Series Pneumatic Ball Valve.

Pneumatic actuator ball valve is a new type of valve that has been widely used in recent years. It has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of ball valve is widely used plastic, which has good sealing performance, and has also been widely used in vacuum system.

4. Easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

5. The maintenance is convenient, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.

6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, the valve sealing surface will not be eroded.

7. It has a wide range of applications, with diameters ranging from small to several millimeters to several meters, and can be applied from high vacuum to high pressure.

Pneumatic ball valves have been widely used in petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets and other sectors, as well as people's daily life.
