Oil flow control valve
--- The oil flow control valve makes it possible to use
simultaneously two hydraulic cylinders, or simulta-
neous use of power lift and one auxiliary cylinder.
With the oil flow control valve the oil flow can be
adjusted so that it suits the implement, when ma-
ximal flow is not needed for e.g. speed control of
hydraulic motors (together with a special valve of
the motor).
The oil flow control valve is situated between the
pump end plate and the valve block. The oil flow
is adjusted with a knob on the side panel in the
cab.
--- The regulated oil flow is independent of the pres-
sure
Functions:
--- The valve directs the required priority flow (that
can be steplessly adjusted from 2 to 40 litres per
minute) to the spool valve that is mounted bet-
ween the oil flow control valve and the intermedia-
te plate.
--- The rest of t he flow is directed through an external
pipe to the next, downstream spool valves.
X = pressure channel for the regulated oil flow
Q --- X = the surplus flow to other spool valves
