VABP Hydraulic Two Pump "Hi-Low" Unloading Valve, VABP 3/8", Max Flow AP 20 L/min, BP 40 L/min BP , T 60 L/min, Max Pressure 350 bar, Low Pressure 100 Bar

  • Thread Size AP 1/4" BSP, BP 3/8" BSP, U 3/8" BSP, T 1/2" BSP
  • Max Flow AP 20 L/min, BP 40 L/min, T 60 L/min
  • Max Pressure 350 Bar
  • Low Pressure 100 Bar

USE AND OPERATION:

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.

 

MATERIALS AND FEATURES:

Body: zinc-plated steel.

Internal components: grounded and hardened steel.

Seals: BUNA N standard 

Leakage: Guided poppet - negligible leakage.

 

CONNECTIONS:

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.

 

 Oil temperature 50° C – Oil viscosity: 30
