The ARI Check Valve prevents backflow in steam, water, condensate and process pipelines. The spring-loaded disc closes instantly when flow reverses, protecting upstream pumps and boilers from damaging back-pressure. Compact wafer / lugged body installs between flanges with minimum face-to-face length. 1.4408 Stainless Steel body, PN40 DN250.
