Proportional Pressure Regulators

QPV Series valves use closed-loop pressure control.

Output pressure, proportional to an electrical command signal, is unaffected by changes in supply pressure. An inlet solenoid valve shifts proportional to flow and maintains system presence. The variableorifice effect controls pressure at low-flow conditions and avoids the digital steps of traditional on/off solenoids. The Series is available in a wide range of electrical command inputs and analog outputs. An IP65 enclosure houses the unit.
