V-Type Ball Valve Pneumatic V-Flange Ball Valve
Pneumatic V-ball valves only need to rotate 90 degrees of gas operation and very small torque to close tight. The completely equal body cavity provides the medium with little resistance, through the flow channel. Ball valves are generally considered suitable for direct open and close use, but recent developments have designed ball valves for throttling and flow control. The main feature of the ball valve is its compact structure, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be integral, can also be combined.

Pneumatic V flange ball valve features
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.
2, simple structure, small volume, light weight.
3, tight and reliable, ball valve sealing surface material is widely used in plastic, good sealing, in the vacuum system has also been widely used.
4, easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90 degrees, easy to remote control.
5, convenient maintenance, pneumatic ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
