Manual and Pneumatic Gate Valves

Manual and Pneumatic Gate Valves
  • In situ removal of gate and linkage mechanism for easy servicing.
  • Compact design with high conductance
  • Long  periods of use between maintenance
  • Low vibration and shock
  • Vacuum brazed to 1100°C to eliminate virtual leaks

The Edwards GV range of stainless steel, bellows sealed gate valves is designed for applications requiring overall leak tightness and a minimum of hydrocarbon in the residual atmosphere. These superior quality valves offer high vacuum integrity coupled with maximum conductance.

The valves are available with flange options of ISO, CF (metal sealed) for applications at ultra high vacuum requiring increased bakeout temperatures.
