(54)Wafer check valve assembly and related methods of use


(57) Improved flow control assemblies for fluid systems (e.g., industrial and/or commercial systems) are provided. More particularly, the present disclosure provides for advantageous wafer check valve assemblies for fluid systems (e.g., piping systems or the like). The present disclosure provides for advantageous wafer check valve assemblies that include an angled sealing surface, which allows the disc member to seal even with the valve assembly in the horizontal position, and/or to seal without the aid of a spring. Improved, convenient, low-cost and/or effective systems and methods for utilizing improved wafer check valve assemblies in fluid systems (e.g., piping systems or the like) are provided.
