Manual Operation In-Line Isolation Valves
Easy to use
Bellows sealed mechanism
High conductance
The IPVMK 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).
