Emerson Process Management has introduced the Fisher Z500 line of metal-seated ball valves to its severe service portfolio. Fisher Z500 metal-seated valves are engineered to withstand higher temperatures, pressures, and more erosive conditions than a standard on/off ball valve, providing increased reliability and protection of critical assets in demanding applications. A bi-directional sealing design offers a unique solution to process back pressure and shutoff requirements in both flow directions, safeguarding control valves and other equipment in the line.
Fisher Z500 valves are designed with an integral metal seat and self-energized metal body gasket to help eliminate leak paths and withstand extreme temperature changes. Live-loaded packing, side-mounted brackets and fixed centerlines help reduce side loads on the packing and decrease overall wear for a longer service life. This addition of on/off valves to the Fisher portfolio complements the existing control valve offering and helps ensure seamless integration between products.
