In a circuit which uses two parallel pumps, this valve unloads the larger pump to tank once the pressure setting of BP has been reached. From this point the circuit will only be supplied by the smaller pump at a higher pressure AP, therefore consuming less energy.



Body: zinc-plated steel.

Internal components: grounded and hardened steel.

Seals: BUNA N standard 

Leakage: Guided poppet - negligible leakage.



Connect BP to the higher flow pump, AP to the lower flow pump, T to the tank, M to the eventual manometer and U to the hydraulic circuit.
