Overview
Overview
The LoPro™ LPV1-40-IK-CNVS Inline Vacuum Valve with an inline body configuration, ISO-KF NW40 flanges, and Viton seals has pneumatic actuation. 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.
