Lift control spool valve - Open Centre
E . Lowering position
The solenoid valve (7) is activated to lower the draw-
bars (Fig. 7).
The lowering spool (3) is moved downwards. Its posi-
tion allows oil to return from the rams via the port (V)
to the return R1.
N
OTE: The lowering phase has no effect on the flow
rate control spool (4). The continuity flow rate N is thus
directed to the pump via the transfer pipe.
