Dual pump high and low flow unloading valve
Dual pump high and low flow unloading valve
Use and operation:
This valve can be used in the circuit of a duplex pump to release excess oil from the high flow pump to the tank when the pressure reaches the set value. From this moment on, energy is saved when operating at high pressure with the low flow pump on the actuator.
Application:
Connect BP to the high flow pump, AP to the low flow pump, T to the tank, M to the final pressure gauge and U-type gauge.
