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 comprising sintered cemented carbide. 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. In some embodiments, the sintered cemented carbide is an inlay coupled to the valve head.
