1.Excellent sealing performance, often using metal sealing or high vacuum rubber sealing structures, which can effectively prevent external gases from infiltrating the vacuum system and maintain the vacuum degree of the system.
2.The opening and closing torque is small, and the internal flow channel of the valve is designed to be smooth, reducing gas flow resistance and adapting to low pressure differentials in vacuum environments.
3.The material selection is strict, usually using corrosion-resistant and low gas release materials such as stainless steel and aluminum alloy to avoid releasing gas and damaging the vacuum environment.
4.Some vacuum valves (such as ultra-high vacuum valves) have baking and degassing functions, which can remove the adsorbed gas inside the valve by heating, meeting the requirements of ultra-high vacuum systems.
