Copeland designs and manufactures metal seated ball valves with high strength stainless metal seats and balls overlayed with carbides or ceramics. 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, rigerous 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. Price, availability, quality and the long term cost of valve ownership are all important.
