Manual Operation Right Angle Isolation Valves

Manual Operation Right Angle Isolation Valves
  • Easy to use
  • Bellows sealed mechanism
  • High conductance

The PVMK is a quick acting, bellows sealed, right-angled lever operated valve and is available with either an aluminium or stainless steel body. The lever, connected to a self lubricating plastic cam‑piston, actuates the valve stem and valve plate through PTFE bearings. The valve plate ‘O’ ring groove is vented to prevent gas bursts. The valves are designed to operate down to 10- 9 mbar and up to a pressure of 2100 mbar (30 psi).
