Vacuum Series
The VP-700 Series air valve switch is a pilot-actuated pressure valve with a precision-adjustable pilot setpoint. Ideal for applications requiring intrinsic safety, pneumatic sequencing, and accurate pressure relief. Four mounting styles are available for design flexibility. Valves can be ordered as normally open or normally closed and pilot actuation can be factory preset.
