Disc type welded metal bellows vacuum valve selection introduction 1. It is necessary to have a clear understanding of the general structure principles of various vacuum valves. 2. For the same vacuum valve, select its valve model after comparing the structure, performance, parameters, scope of application, air leakage rate, sealing material, use method and other comprehensive factors. 3. To install the vent valve on the vacuum chamber, choose the type of vent valve according to the amount of gas in the vacuum chamber and the length of time that the door of the vacuum chamber needs to be opened. 4. There are three driving modes of vacuum valve: manual, electric and pneumatic. The valve that uses that drive mode should be considered from the needs of the vacuum system. 5. Ultra-high vacuum valves are commonly used in ultra-high vacuum systems. 6. The vacuum valve can be used alone, arranged between the vacuum chamber and the vacuum pump or on the vacuum chamber. It is a necessary component of a general vacuum system. But most vacuum valves are used in vacuum pumping units. 7. The vacuum diaphragm valve, due to its simple structure, small size, light weight, and good sealing performance, is suitable for pre-pumping and pre-pumping pipelines and non-corrosive gases with a temperature of -25°C to 80°C."
