The actuator pushes plunger (4) against the force of metering spring (8) and centering spring (10). DUMP stem (14) moves down with the plunger. The oil flows out of passage (16) to the DUMP end of the valve spool. The pressure of the supply oil on the end of the TILT valve spool moves the spool into the
