Abstract:
1. A valve comprising: a valve body including an inlet, an outlet, and an inner surface defining a fluid flow passage between the inlet and the outlet; a free floating poppet disposed in the valve body and moveable between at least a closed position, in which the free floating poppet at least substantially restricts fluid from flowing through the fluid flow passage, and an open position, in which fluid is allowed to flow through the fluid flow passage, the free floating poppet including a base section and a cutback section, the base section having a first cross sectional area, and the cutback section having a second cross sectional area that is less than the first cross sectional area; the base section being a first distance from the inner surface to form a first diametrical clearance for the fluid flow passage, and the cutback section being a second distance from the inner surface, greater than the first distance, to form a second diametrical clearance for the fluid flow passage that is greater than the first diametrical clearance.
