What is the vacuum valve introduction

A vacuum valve is a valve whose working pressure is lower than the standard atmospheric pressure applied to the vacuum system. Vacuum valve English name (Vacuumvalves) is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow adjustment function and closed sealing characteristics. Vacuum valves have a wide range of applications in large and medium diameter, medium and low pressure.
         The vacuum valve can be divided into low vacuum, medium vacuum, high vacuum and ultra high vacuum by vacuum degree. The factory produces a series of high vacuum valves.
         Valve classification:
Common types of vacuum valves include high vacuum ball valves, vacuum butterfly valves, high vacuum diaphragm valves, electromagnetic vacuum belt inflation valves, electromagnetic vacuum flapper valves, vacuum trimmer valves, high vacuum flapper valves, and ultra-high vacuum flapper valves.
Drive type:
The vacuum valve has four types: manual, pneumatic, electric and electromagnetic. It is powered by hand, compressed air, power supply and electromagnetic force. The actuator is used to drive the valve plate (valve, spool) to open and close the valve.
