ABSTRACT:
A valve includes a valve body and a free floating poppet. The valve body includes an inlet, an outlet, and a fluid flow passage therebetween. The free floating poppet is disposed in the valve body, and is 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 includes a base section and a cutback section. The base section has a first cross sectional area. The cutback section has a second cross sectional area that is less than the first cross sectional area.
