VALVES, VALVE ASSEMBLIES AND APPLICATIONS THEREOF

Abstract:

Valves and valve assemblies are described herein employing architectures which can mitigate degradative wear mechanisms, thereby prolonging life of the assembly. In one aspect, a valve comprises a head including a circumferential surface and a valve seat mating surface. Leg members extend from the head, wherein thickness of one or more of the leg members tapers in a direction away from the head to induce laminar fluid flow around the head. The valve can also comprise a seal coupled to the circumferential surface of the head. In some embodiments, an exterior surface of the seal exhibits a radius of curvature maintaining laminar fluid flow around the valve. Additionally, the seal can overlap a portion of the valve seat mating surface, in some embodiments.
