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. EN-JL1040 Cast Iron body, PN16 DN20.
