Vacuum valves: Edwards® (formely known as BOC Edwards® ) vacuum valvesEdwards® PVMK Manual Operation Isolation valves
Edwards® PVMK MANUAL OPERATION ISOLATION VALVES
- PVMK - aluminium body
- PVMKS - stainless steel body
- Quick acting, lever operated valves
- PVMK valve lever is connected to a self-lubricating plastic cam-piston
- Cam piston actuates
the valves stem and valve plate via PTFE bearings
- PVMK valve
plate ‘O’ ring groove is vented to prevent gas bursts.
- PVMK valves are designed to operate down to 10-9 mbar / 8 x
10-10 Torr and up to a pressure of 2100 mbar / 1575 Torr
(30 psi).
