Ripper Tip Control Valve (Ripper Tip In)
00011
When the pilot control pressure causes the valve spool to move to the TIP IN position, cylinder oil from the head
end passage flows through the signal oil 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 head end passage to the head
end of the ripper tip cylinders. The ripper tip cylinders tip the ripper inward.
Return oil from the rod end of the ripper tip cylinders flows through the rod end passage, around the valve spool,
and through the outlet passage to the tank.
