Abstract: A valve assembly for controlling the flow of hydraulic fluid through a subsea control system providing hydraulic control of underwater equipment and having a female member adapted to be connected to the underwater equipment and having a retrievable male member coacting with the female member in which each of said members includes a plurality of flow control passageways. A laminated manifold block having top, middle and lower layers is connected to the top of the male member and supports a plurality of individual valve housings releasably secured to the top layer of the manifold block for receiving control valves. The laminated manifold block includes fluid supply, fluid exhaust and fluid outlet passageways between the control valves and the controlled underwater equipment. The laminated manifold block is longer than the width of the male member thereby accommodating larger control valves to provide an adequate volume of fluid for control purposes. The manifold block may include a plurality of separate fluid supply manifolds for controlling different underwater equipment requiring different actuating pressures.
