Installed on the discharge side of a pump, the valve senses high pressure at pump discharge (valve inlet) and low pressure at the pump suction. Valve modulates to hold differential pressure constant, thus assuring pump is at optimum point on its curve.

FILTER BYPASS CONTROL

In a filtered liquid application where loss of flow cannot be tolerated, the model 110 allows flow should the filter become clogged.
