Abstract:
1. A valve assembly for reducing cavitation, comprising: a housing having a fluid inlet and a fluid outlet; a seat disposed within the housing intermediate the fluid inlet and outlet, the seat including a wall defining an inner chamber and a plurality of elongated slots formed in the seat wall; and a disk guide associated with the seat such that the seat and disk guide are slidably movable relative to one another, the disk guide including a wall defining an inner chamber and a plurality of elongated slots formed in the disk guide wall, wherein the elongated slots are formed in the disk guide wall such so as to direct the fluid towards the housing at a non-direct angle; wherein the disk guide and seat are moved into a closed position, fluid is prevented from passing from the housing fluid inlet to the housing fluid outlet; and wherein the disk guide and seat are moved into an open position, fluid is directed from the housing fluid inlet through the seat elongated slots, into the seat inner chamber, into the disk guide inner chamber, and through the disk guide elongated slots to the housing fluid outlet resulting in reduced fluid pressure while minimizing cavitation.
