It allows flow in one direction and closes automatically to prevent backflow without requiring manual operation. The valve body is cast bronze conforming to ASTM B-62 and ASTM B-140 C31400, with a PTFE disc and regrindable PTFE seat. Rated to 200 psi non-shock cold working pressure and 125 psi saturated steam service up to 353 degrees F, this valve is built for demanding industrial and mechanical applications. A screw-in bonnet provides access to the internals, making disc and seat service straightforward in the field.\u003c\/p\u003e\u003cp\u003eThe T-413-Y-1\/2 is suited for steam, water, oil, and gas service across horizontal and vertical mount orientations. The Y-pattern body geometry produces lower pressure drop compared to straight-body check valves, making it a practical choice in lines where flow efficiency matters. Typical installations include boiler rooms, mechanical rooms, and process piping where backflow prevention is required. This valve is approved for non-potable water applications only. Use in U.S. drinking water applications is prohibited after January 3, 2014, per applicable lead law compliance requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eY-pattern body reduces pressure drop across the valve compared to standard swing check designs\u003c\/li\u003e\n\u003cli\u003eRenewable PTFE disc and regrindable seat allow in-field servicing without full valve replacement\u003c\/li\u003e\n\u003cli\u003eScrew-in bonnet design provides straightforward access for inspection and maintenance\u003c\/li\u003e\n\u003cli\u003eRated to 200 psi non-shock cold working pressure and 125 psi saturated steam to 353 degrees F\u003c\/li\u003e\n\u003cli\u003eSupports horizontal and vertical mount installation orientations\u003c\/li\u003e\n\u003cli\u003eConforms to MSS SP-139 and ASTM B-62, ASTM B-140 C31400, ASTM B-16\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for 1\/2 inch threaded NPT piping systems in steam, water, oil, and gas service.
