Electric Actuated High Vacuum Ball Valves: Overview & Technical Parameters

The Electric Actuated High Vacuum Ball Valve is a high vacuum ball valve applied in high vacuum systems (also applicable under a certain pressure) to open or cut off gas flow. The actuator adopts a rotary electric and electronic regulating drive device, which realizes the control of valve opening, closing or intermediate position through external power supply cut-off or external input signals. This valve features a compact and aesthetic appearance structure and a compensating design of the sealing seat. It has the advantages of automatic compensation for sealing seat wear, reliable sealing and long service life. The applicable working media are various gases or liquids with acidity and alkalinity.
