ABSTRACT:
In a conventional spool valve, the nut holding the diaphragm to the spool valve stem is replaced by a retaining ring, thereby simplifying the machining operation and eliminating the problems caused by damaged threads. A good seal is nevertheless achieved by providing an insert molded diaphragm having a bead around its axial aperture, which is compressed against the radial flange of the valve stem, and such that the retaining ring will maintain the compressed condition of the bead against the radial flange to maintain a good seal.
