Ripper Lift Control Valve (Ripper Raise)
00011
When the pilot control pressure causes the valve spool to move to the RAISE position, cylinder oil from the
passage flows through the passage to the chamber. The oil functions as signal oil. The signal oil opens the resolver
and flows to the previous control valve and to the inlet manifold. The increase of pump oil flow to the inlet passage
opens the load check valve. The oil flows through the load check valve, through the passage, and around the valve
spool. The oil flows through the rod end passage to the rod end of the ripper lift cylinders. The ripper lift cylinders
then raise the ripper.
Return oil from the head end of the ripper lift cylinders flows through the head end passage, around the valve
spool, and through the outlet passage to the tank.
