(5) Check valve The retract flow control valve controls the oil flow from the hoist control valve to the ejector sequence valve when in the RETRACT position.During the retract cycle, oil from the hoist control valve enters the manifold through port (3). Oil flow is regulated by retract flow control valve (2) before exiting through port (4) to the ejector sequence valve. As pressure increases, retract flow control valve (2) moves against spring force and allows excess oil to return to the hydraulic tank through port (1).During the eject cycle, return oil from the ejector sequence valve flows to port (4) through check valve (5) to port (3). Oil from port (3) returns through the hoist control valve to the brake cooling system.
