All US Valve check valves are tested to API 598 and must meet or exceed all applicable API, ANSI and ASTM Standards.<\/p>\n<p>Dual Plate Wafer Check Valves offer some impressive advantages over other types of check valves.<\/p>\n<ul>\n<li><strong>Low Pressure Drop (High Cv)<\/strong><br \/>\nDual plate wafer check valves have larger open area than other designs, thus reducing pressure drop compared to swing, lift or other check valves.<\/li>\n<li><strong>Light Weight<\/strong><br \/>\nReduces weight by 80\u201390% compared to conventional Flanged check valves.<\/li>\n<li><strong>Lower Cost<\/strong><br \/>\nLight weight, compact profiles and the elimination of flanges allows DPW check valves to be manufactured more economically than other designs, especially as pipe diameters increase.<\/li>\n<li><strong>Alleviates Water Hammer<\/strong><br \/>\nOur spring activated discs are designed to close our valves quickly. This assures high performance, eliminating chatter and creating dynamic responsiveness in a non-slam design.<\/li>\n<li><strong>Simple Installation<\/strong><br \/>\nEasier to install, remove and replace in both new and existing piping systems.<\/li>\n<\/ul>\n<p><strong>Variety of Configurations<\/strong><br \/>\nUS Valve offers a wide variety of wafer bodies in different styles and materials. These can be assembled with any one of our standard disc, optional spring and elastomer seal choices to make a valve that exactly fits your application.
