What is ball valve

Features of ball valves

 thrust bearing reduces the friction torque of the valve stem, which can make the valve stem stable and flexible long-term operation.

 anti-static function: in the ball, stem, valve body between the spring, can be generated in the process of switching electrostatic export.

because ptfe and other materials have good self-lubrication, and the friction loss of the ball is small, so the service life of pneumatic ball valve is long.

 small fluid resistance: pneumatic ball valve is all valve classification of the least fluid resistance, even reduced diameter pneumatic ball valve, its fluid resistance is quite small.

 the valve stem seal is reliable: because the valve stem is only rotating motion without lifting motion, the packing seal of the valve stem is not easy to damage, and the sealing capacity increases with the increase of the medium pressure.

seat sealing performance is good: the sealing ring made of ptfe and other elastic materials, the structure is easy to seal, and the valve sealing capacity of pneumatic ball valve increases with the increase of medium pressure.

fluid resistance is small, full diameter ball valve basically no flow resistance.

 simple structure, small size, light weight.

Tight and reliable. It has two sealing surface, and the sealing surface of the ball valve material is widely used in a variety of plastics, good sealing, can achieve complete sealing. It has also been widely used in vacuum systems.

 easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90°, easy to remote control.

convenient maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.

When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes, it will not cause the erosion of the sealing surface of the valve.

 wide range of application, diameter from a few millimeters, to a few meters, from high vacuum to high pressure can be applied.

 because the ball valve in the process of opening and closing wipe, so can be used with suspended solid particles in the medium.

High processing accuracy, high cost, not suitable for use in high temperature, such as impurities in the pipeline, easy to be blocked by impurities, resulting in the valve can not be opened.
