Vacuum valves are used in vacuum systems to regulate, isolate, or direct gas flow. They are commonly found in semiconductor manufacturing, vacuum coating, metallurgy, and research equipment where maintaining a specific vacuum level is critical.
The body is typically made of stainless steel 316L (per ASTM A351) for corrosion resistance, and the seals are made of VITON (per ASTM D2000) for vacuum compatibility. These materials are specified in the directory entry.
The leak rate is specified as ≤1.3e-10 Pa·m³/s, tested with a helium leak test per ISO 27895. This ensures the valve maintains vacuum integrity.
The valve can be actuated manually, pneumatically, or electrically. For pneumatic actuation, the actuation time is 0.5 to 2.0 seconds, and the control voltage is 24 V DC (±10%) with a solenoid pilot.
