TWO PUMP "HI-LO" UNLOADING VALVES FLANGEABLE ON LOW-PRESSURE PUMP
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 pump at higher pressure, consuming less energy. This valve is designed for direct flanging on lower flow pump. To adjust the high pressure you have to mount an inline relief valve.
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.
