Simultaneously the line from the rod side of the ram enters the loader valve at port A and is connected to exhaust at D. The rams extend and raise the arms.
When the lower operation is selected, servo-pressure moves the spool so that the pressure and return line galleries are interchanged. Pressure oil is sent from port A and port B is connected to the exhaust. The rams retract to give a controlled lowering of the arms.
