It is designed to allow flow in one direction and prevent backflow in potable water, hydronic, and general-purpose plumbing systems. The body is cast from UNS C89844 lead-free bronze alloy, meeting lead-free compliance requirements for drinking water applications. A phosphor-bronze spring provides consistent cracking performance at 0.50 psi, and the full-port design delivers a Cv rating of 45, minimizing pressure drop across the valve. A nitrile butadiene rubber seal provides a reliable shut-off. Licensed plumbers and pipefitters install this valve in commercial and residential systems.\u003c\/p\u003e\n\u003cp\u003eThis check valve is suited for inline installation in 2-inch FNPT-threaded piping systems carrying water or compatible fluids up to 180 degrees F. Rated at 250 WOG, it is appropriate for cold and hot water supply lines, hydronic heating circuits, and irrigation mains where backflow prevention is required. The FNPT x FNPT end connections allow direct installation into standard threaded pipe runs without adapters. Both residential and light commercial plumbing contractors commonly specify this valve where a compact, threaded check valve is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free UNS C89844 bronze body meets lead-free requirements for potable water service\u003c\/li\u003e\n  \u003cli\u003eLow 0.50 psi crack pressure for dependable opening under normal system flow\u003c\/li\u003e\n  \u003cli\u003eFull-port design with Cv rating of 45 minimizes flow restriction\u003c\/li\u003e\n  \u003cli\u003eFNPT x FNPT end connections for straightforward installation in threaded pipe systems\u003c\/li\u003e\n  \u003cli\u003ePhosphor-bronze spring and nitrile butadiene rubber seal for durability and reliable shutoff\u003c\/li\u003e\n  \u003cli\u003e250 WOG pressure rating suitable for typical residential and commercial water systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation inline check valve for 2-inch FNPT-threaded plumbing and hydronic piping systems requiring lead-free bronze construction and 250 WOG service rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Apply thread sealant or PTFE tape to the male threads of the mating pipe before threading in the valve body.
