Hydraulic Pump Bypass Valve

The bypass valve is mainly utilised in applications where the F1 pump is driven from the crank-shaft through a cardan shaft, or when it is installed on an engine PTO. The BPV bypass valve should be disengaged during transportation when the pump is operating constantly and the engine is running at max rpm; the hydraulic system is not sized for the large flow that would otherwise go through it.

The BPV valve substantially reduces the energy loss during transportation. The valve installs directly on top of the pump end cap with a pressure port ’banjo’ fitting and an inlet port spacer bushing with two cap screws; refer to the illustration to the right. As the BPV valve is symmetrical, it can be ’turned 180°’ to prevent interference with chassis components; it can be utilised for either left hand or right hand pumps. The valve function must only be activated or released (by means of the 24 VDC solenoid) at no-load (below 20 bar) system pressure.
