VPMW-700 Series

Adjustable Vacuum Piloted 3 Way Pressure Switch

The 700 vacuum series is a vacuum piloted 3-way valve with a positive pressure output. Perfect for use in applications which require intrinsic safety, pneumatic sequencing, and precise pressure relief. Three mounting styles are available for design flexibility. Valves can be ordered as normally open or normally closed and pilot actuation can be factory preset.
