ABSTRACT:
A self-cleaning valve plug and seat assembly for use within a valve chamber comprises a seat member extending into the chamber and having an inwardly converging frustconical seating surface thereon. A cylindrical skirt portion extending inwardly coaxially from the seating surface includes ports therein connecting with a fluid passage extending axially through the seat member. A valve plug includes a cylindrical bore extending partway thereinto and adapting the plug for sliding movement over the seat member skirt portion. The plug includes a surface intersecting the bore at an actute angle to provide a circular cutting edge at the open end of the bore. Means are provided for moving the plug axially toward and away from the seat member so that the plug is disposed clear of the seat member ports in the open valve position and covers the ports in the closed valve position with the plug cutting edge engaging the seating surface of the seat member in fluid-tight sealing relation.
