ABSTRACT:
A valve is provided for operation within a substantially cylindrical conduit section having an internal threaded portion adjacent a radially inwardly extending shoulder. A cylindrical apertured valve guide having external threads adjacent one end and an internal circumferential groove adjacent the same end is disposed in threaded engagement with the internal threaded portion of the conduit with the end of the guide abutting said shoulder. An annular sealing gasket is disposed on said shoulder within said groove to provide a valve seat for a spherical shaped valve member which is provided with a cylindrical side portion which is slidable within said cylindrical guide. The valve member also has an axially extending stem extending through an aperture in the opposite end of said valve guide and a spring surrounds said stem to bias the valve member into engagement with the seat.
