High vacuum valve means a valve, whose working pressure is lower than the standard atmosphere. The most basic requirement for this kind of valve is to ensure a high degree of sealing and the dense of structure and gasket material to the connection. High vacuum valve is a kind of vacuum valve, which is consistent with the equation: p=1*10-7 mm Hg.
Vacuum valve is used when a vacuum must be maintained in a closed system, and it is used to control gas flow into a chamber, isolate, vent, provide relief or control conductance. There are mainly two ways of the vacuum valve connection: the flange connection and the threaded connection. The flange connection including: smooth-type, bump type, tenon slot, trapezoidal trough, lenticular, o-ring type; and the threaded connection including: direct seal and indirect seal.
High vacuum valve is extensively used in vacuum industry, especially, in the manufacturers producing vacuum box and coating machine. Gate, inline and angle valves are the most common types of vacuum valves for high vacuum applications. High vacuum valve is essential shut-off any vacuum system and it is used in the vacuum lines or directly at the vacuum chamber.
