Apco 12"-126LB Check Valve, 12 in Dia, Swing, Rubber Flapper, Ci/Di Body, Flanged, 175 PSI Cwp

The Apco 12"-126LB rubber flapper check valve is a 12-inch nominal diameter, swing-type check valve engineered to prevent backflow in fluid systems. It incorporates a rubber-covered flapper, ensuring silent, non-slam operation and providing resilient seating for tight shut-off against reverse flow. Constructed with a cast iron body (ASTM A126 class B) or ductile iron (ASTM A536), the valve features a flapper commonly molded from materials such as Buna-N, EPDM, or neoprene, typically affixed to a stainless steel hinge pin. This valve type is commonly equipped with flanged end connections conforming to ANSI B16.1 class 125 standards and is rated for a cold working pressure (CWP) of 175 PSI. Its design facilitates full flow with minimal head loss.
