3/4″ TWO PUMP “HI-LOW” UNLOADING VALVE

Use and Operation
This valve is used in a 2 parallel-working pumps circuit in order to release the excess of the higher flow pump to the tank when this gets the required pressure setting. Since this moment and on the actuator works with the lower flow pumps at higher pressure, consuming less energy.

Materials and Features

• Body: zinc-plated steel
• Internal Parts: hardened and ground steel
• Seals: BUNA N standard
• Tightness: minor leakage

Applications:

Connect BP to the higher flow pump, AP to the lower flow pump, T to the tank, M to the eventual manometer and U as for necessity.
