the valve is partially open. Y-port (P3) is open to Z-port (P2) but is being
restricted by the control pilot. The pilot control is a variable orifice that regulates the
pressure at Y-port (P3) by controlling the flow through Z-port. Increasing or decreasing the
Y-port pressure (P3) causes the piston to change positions.
