Vacuum ball valve

High platform vacuum ball valve is a medium flow ball valve suitable for opening or closing pipelines in vacuum system. The vacuum ball valve is driven by rotary electric and electronic control valves. The electric high vacuum ball valve can realize on, off or intermediate position control through external power switching (using manual indicating switch or computer control) or external input signal. The electric high vacuum ball valve is straight through and sealed by a spherical surface, so it can be used under vacuum and low pressure. And can be installed anywhere.

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 the advantages of simple structure, small volume and light weight.

(3) Close and reliable. It has two sealing surfaces. At present, the sealing surface materials of the electric high vacuum ball valve are widely used in various plastics with good sealing performance, which can realize complete sealing. Electric high vacuum ball valve has also been widely used in vacuum system.

(4) Simple operation and quick opening and closing. The electric high vacuum ball valve rotates 90 ° from full open to full close. Electric high vacuum ball valve for remote control

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

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

(7) Electric high vacuum ball valve is applicable to a wide range of applications from small to several millimeters to several meters, from high vacuum to high pressure.

(8) Since the ball valve has wiping performance during opening and closing, the electric high vacuum ball valve can be used in the medium with suspended solid particles.

working principle:

Through 90 ° rotation of the handle, the manufactured ball with a through cavity is driven to open or close the valve, so as to realize the medium flow.
