Vacuum valve

Vacuum valve VS 16
  • Valves of the series VS, VS C and VS B are butterfly-type butterfly valves.
  • A round valve plate with an outer sealing ring rotates about an axis running transversely to the valve housing. 
  • As a result, the valves release virtually the entire cross-section and have very good conductances. 
  • The valve housings are machined in one piece from solid material and require only a single elastic shaft seal which is only subjected to rotation, in addition to the valve disc seal.
  • These valves have very low leak rates and low gas emissions. 
  • In the C version, the valve stem seal is made of chemically resistant perfluoroelastomer.
Technical information:
  • Nominal width of flange: 16 mm
  • Wetted materials: SS, FKM, NBR
  • Leakage rate: 1x10-6 mbar l/s
  • Fitting length between flanges: 65 mm
  • Weight: 0.6 kg
