Emerson 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; the aim being to provide increased reliability and protection of critical assets in demanding applications within refining, conventional power generation, mining and other industries.
A patented, bi-directional sealing design offers a solution to process back pressure and shut-off requirements in both flow directions, safeguarding control valves and other equipment in the line, says the company
The valves are designed with an integral metal seat and self-energised metal body gasket to help eliminate leak paths and withstand extreme temperature changes.
Live-loaded packing, side-mounted brackets and fixed centrelines help reduce side loads on the packing and are designed to decrease overall wear for a longer service life.
