ABSTRACT:
An inlet check valve for use with inflatable buoyancy tubes such as are used on life rafts and escape slides. The inlet check valve being freely rotatable within the flange affixed to the raft fabric thereby allowing for easier packing and deployment due to the design of the inlet check valve to rotate within the flange to seek a lower stress orientation. In addition, the inlet check valve is readily removable from the flange if valve replacement or repair is needed. Furthermore, a manifold may be used which includes multiple inlet check valves coupled together.
