ABSTRACT:
A hull and backup valve assembly for a submarine includes a valve body made of the same material as the hull; thus, the valve body can be welded directly to the hull. The flow path of the valve is straight and disposed at an angle relative to the surface of the hull, facilitating the removal of the valves' components for inspection and repair. Corrosion resistance is obtained through the extensive use of clad overlays and internal barriers that completely protect the steel surfaces from seawater contact. The valve stem is made of a titanium alloy and mates directly to the rack of a hydraulic actuator, thereby further reducing the parts and volume required for the valve assembly.
