"DISC-TYPE CHECK VALVE" ABSTRACT OF THE DISCLOSURE The valve comprises a bored housing formed of two segments. A discrete annular seat member is positioned on an annular shoulder formed in one segment. A guide member, comprising spaced apart legs and an apertured end wall is positioned on the seat member. A cylindrical, resilient plastic disc is positioned to seat against the seat member to close off flow through the bore and to slide within the guide member when unseated. Flow bypasses the unseated disc by moving through the spaces between the guide member legs and out through the end wall aperture. The plastic disc provides a particularly good seal and thus erosion of the seat is diminished. Having the seat member removable reduces reconditioning costs.
