Loader Valve Neutral Circuit
Oil from the pump enters the valve at 1. When all
the spools are in the neutral position as shown, the
oil passes around the waisted central position of the
spools and flows past the main relief valve 6 and on
to feed the main pumps and directional joystick via
outlet line 2. Oil trapped in the lines prevents
movement of the rams. Oil also fills the parallel
gallery X.
