SANKEY designs and manufactures metal seated ball valves with high strength stainless metal seats and balls over-layed with carbides. Metal seated ball valves are required for many extreme service conditions involving abrasives, corrosives, high cycle rates or extreme temperature and pressure. These conditions require simple, well-built but rugged designs, metal seats, rigorous testing and carefully chosen materials. Valves should be tested to nationally recognized standards and, then again, with in-house methods designed to simulate the actual process conditions.
New developments in technology and our experience addressing severe service conditions have helped us to develop several lines of new productsValve Application:
