Wafer Type Ball Valve

Product Details:

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 products
