Vacuum valve manufacturers
Vacuum valves are used to control, isolate, vent, or protect systems operating under vacuum conditions. They are designed to maintain leak-tight sealing at low absolute pressures and to prevent air ingress that could affect process quality, contamination risk, or equipment performance. Typical vacuum valve types include isolation valves, throttle valves, gate valves, angle valves, and vacuum relief valves.
Material and seal selection depends on vacuum level, gas purity, temperature and chemical compatibility. High vacuum and ultra-high vacuum applications often require metal-sealed valves and low-outgassing materials. Vacuum valves are used in semiconductor processing, laboratory systems, thin film deposition, vacuum furnaces, pharmaceutical production, and industrial degassing and drying processes.
