Overview
Overview
The LoPro™ LPV1-50-AK-CLVS Vacuum Valve with an anglebody configuration, ISO-KF NW50 flanges, Kalrez seals has pneumatic actuation and a limit switch. It has a small footprint that fits easily into existing, and new, vacuum systems. A formed stainless steel bellows prevents outgassing, virtual leaks, and particle entrapment between bellows convolutions that extends the valves life cycle over a conventional O-ring shaft sealed valve.
