The vacuum ball valve refers to the ball valve whose working pressure is lower than the standard atmospheric pressure, forming a certain vacuum. The valve is a straight through type, sealed by a spherical surface, which can be used in both vacuum and low-pressure conditions. It can be installed at any position to connect or cut off the medium flow in the vacuum system pipeline.

characteristic:

(1) The fluid resistance is small, and the full diameter ball valve basically has no flow resistance.

(2) The electric high vacuum ball valve has a simple structure, small size, and light weight.

(3) Close and reliable. It has two sealing surfaces. Currently, the sealing surface material of electric high vacuum ball valves is widely used in various plastics, with good sealing performance and can achieve complete sealing. Electric high vacuum ball valves have also been widely used in vacuum systems.

(4) Easy to operate and fast to open and close. The electric high vacuum ball valve rotates 90 ° from fully open to fully closed. Electric high vacuum ball valve facilitates remote control

(5) Easy maintenance, simple ball valve structure, and generally effective sealing ring. Easy to disassemble and replace.

(6) When fully open or fully closed, the sealing surfaces of the electric high vacuum ball valve and valve seat are isolated from the medium. When the medium passes through, it will not cause corrosion on the valve sealing surface.

(7) Electric high vacuum ball valves are suitable for a wide range of applications from small to a few millimeters to several meters, from high vacuum to high pressure.

(8) Due to the wiping performance of ball valves during opening and closing, electric high vacuum ball valves can be used in media with suspended solid particles.

working principle:

By rotating the handle 90 °, a precision manufactured ball with a through cavity is driven to open or close the valve, thereby achieving medium flow.
