Unloading Valves

Typical application for the PUV valve is for pump unloading in an accumulator system. When the PUV setting is reached, the PUV opens, venting the PCR valves pilot signal. This unloads the pump until accumulator system pressure drops to 80% of the PUV setting. The PUV closes which blocks the PCR pilot signal to recharge the accumulator and the cycle is repeated. NOTE: Max. PUV flow 3.8 LPM.
