<p>A fluid control valve is disclosed. Preferably, a plastic body member (20) of the cartridge is provided. A valve stem (52) is provided that includes a pair of metal stop elements (56,57) extending radially outward. A metal stop table (65) is mounted around the stem to limit rotational movement of the valve stem through contact with the stop elements. The legs (68,69) have radially-projecting extensions (71,72) which are designed to fit in recesses (73) within the valve housing (13) to prevent rotation of the stop table (65). Excess rotational forces applied to the valve stem after the cartridge reaches a fully open or closed position are translated through the stop table and directly into the valve housing without stressing the plastic body member. <IMAGE></p> |
