It uses a spring actuator to provide positive shutoff without relying on gravity or flow orientation alone. The body is cast bronze with stainless steel and PTFE trim, and the sealing disc is compatible with Buna-N elastomers. Rated at 250 psi working pressure and 353 degrees F, this valve is built for demanding residential and commercial plumbing and hydronic applications. Licensed plumbers and pipefitters install this type of valve in hot and cold water distribution, heating systems, and general fluid service lines.\u003c\/p\u003e\u003cp\u003eThe NL9318A is suited for horizontal or vertical in-line installations where preventing reverse flow is required. Its FNPT end connections make it compatible with standard threaded pipe assemblies. The 125 lb pressure class and 250 psi rating cover a wide range of commercial and light industrial service conditions. This valve is domestically manufactured and carries a 5-year limited warranty. Note: per manufacturer documentation, this valve is not approved for potable drinking water service in California under Section 116875.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpring actuator provides positive backflow prevention independent of pipe orientation\u003c\/li\u003e\n\u003cli\u003eBronze body offers corrosion resistance in hydronic and general fluid service\u003c\/li\u003e\n\u003cli\u003eStainless steel and PTFE trim for durability and chemical compatibility\u003c\/li\u003e\n\u003cli\u003e250 psi working pressure rating handles demanding commercial service conditions\u003c\/li\u003e\n\u003cli\u003eFNPT end connections fit standard threaded pipe assemblies\u003c\/li\u003e\n\u003cli\u003eDomestically manufactured with a 5-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style in-line lift check valve for threaded piping systems rated within the 125 lb pressure class.
