Latest Patents

Robert B. Pratt holds a patent for a Non-rotating Stem Valve. This invention features a rising stem valve that includes a valve body, a two-part valve stem, and a stem guide washer. The valve body is designed with a valve seat situated in a passage between an inlet and outlet port. The two-part valve stem consists of a rotating stem and a non-rotating stem, where the rotating stem has a threaded bore that receives a threaded end of the non-rotating stem. The non-rotating stem is uniquely designed with a non-circular cross-section external to the threaded bore, allowing it to carry a closure head to the valve seat. The stem guide washer is positioned in a way that prevents the stem from rotating when the upper stem is turned.
