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.
