An F2 twin pump fitted with a bypass valve can be
utilised in applications where the pump is operating
constantly i.e. when the pump is driven from the crankshaft through a cardan shaft, or when it is installed
on an engine-PTO. In addition, it can be used when,
temporarily, one of the two circuits is not required; the
power loss is thus reduced as the non-required flow is
not forced through lines and ’open center’ valves.
• 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 connects the outlet and inlet ports of
the pump, and only a small oil flow goes through the
system and to the reservoir.
• The valve is installed directly on top of the pump port
surface with ’banjo’ fittings and two cap screws (refer
to the split view to the right).
• As the BPV valve is symmetrical it can be ’turned 180°’
so as not to interfere with chassis components.The
valve can accommodate left hand as well as right
hand rotating pumps.
• The valve can only be engaged or disengaged
(through the 24 or 12 VDC s
