Overview:

Pneumatic three-piece ball valve is evolved from the valve. It has the same rotation of 90 degrees to mention the action, the difference is that the plug body is a sphere, with a circular through hole or passage through its axis. The proportion of the spherical and the channel should be such that when the ball rotates 90 degrees, the inlet and outlet should all be spherical, thus breaking the flow. Pneumatic three-piece ball valve only need to use the gas rotation 90 degrees of operation and a small turning torque can be closed tight. The fully equal body cavity provides a very small, straight passage for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing use, but the development has been designed to make it a throttle and control flow. The main features of the ball valve itself is compact, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be the whole, it can be modular.

Features:

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

2. Simple structure, small size, light weight.

3. Close and reliable, ball valve sealing surface material widely used plastic, good sealing, in the vacuum system has also been widely used.

4. Easy to operate, open and close quickly, from full open to full clearance as long as the rotation of 90 °, easy to remote control.

5. Easy maintenance, pneumatic ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.

6. When fully open or fully closed, the ball and the seat of the sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion.

7. Wide range of applications, the diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied.
