Abstract
A double acting actuator is used for operating a pair of latches, and is controlled through a manifold that will permit a base end of the actuator to remain under pressure, and accommodate valve and piston leakage by connecting the rod end of the actuator to drain through a small orifice. The manifold additionally has relief valves for providing different pressures for the rod and base ends of the actuator, and a flow divider that provides a low flow to the actuator while the main flow from a pump is used for other hydraulic components.
