ABSTRACT:
A gate valve includes a body with a flow passage therethrough and spaced annular seating members in the body surrounding the flow passage with seal means between the seating members and the body. A gate member is positioned between the seat members and has a surface to intersect and close off the flow passage through the body and has an opening for alignment with the flow passage through the body for flow therethrough. The annular seating members include an annular surface for abutting the gate with an annular teflon seal means in the surface and an annular groove also therein with sealant passage means for communicating with sealant passage means in the body for directing sealant to the groove means. Spaced projecting vertical guide surfaces are provided on the annular seating members for abutting the edges of the gate member to retain it aligned in the body. A stem is threadedly secured with a cylindrical member rotatably carried by the gate member whereby rotation of the stem raises and lowers the gate. The gate member includes a pair of rectangular plate members with means connecting the plate members together while accommodating limited relative movement therebetween with spring means tending to urge said plate members apart.
