Steering Control Valve (Steer Right)
00011
When the steering valve spool is moved to the STEER RIGHT position, the chamber is closed off from the outlet
passage #2. Passage is opened to the steer right passage. Pump oil flows through the priority flow control valve,
opens the load check valve and flows around the control valve spool to the steer right passage. The pressure in the
steer right passage increases and oil is sent through the passage to the chamber. The oil now becomes signal oil.
Some of the signal oil flows through passage #2 to the spring chamber that is behind the priority flow control valve.
The priority flow control valve moves to the left. The remaining signal oil pushes the resolver to the side and the
signal oil flows through passage #1 to the inlet manifold. The inlet manifold sends the signal oil to the compensator
valve in order to upstroke the pump.
As pump oil flow and system pressure increases, the steering oil flow and the pressure through the steer right
passage increases. The increased oil flow through the steer right passage flows through the counterbalance valve
to the steering motor and the machine turns right.
Return oil comes to the steer left passage from the steering motor and from the counterbalance valve. The return
oil flows around the control valve spool and through outlet passage #1 to the tank.
