The body is cast from silicon bronze, which offers strong corrosion resistance in potable water service. A stainless steel spring holds the poppet closed against backflow, and a Buna-N seal provides a reliable shutoff. The valve is rated at 400 psi WOG and connects via female threaded ends on both sides. Each unit ships with the spring, washer, and lock nut included. Installation requires no additional trim components beyond standard thread sealant. Licensed plumbers and water well contractors are the primary installers of this valve.\u003c\/p\u003e\n\u003cp\u003eThis valve is sized at 3\/4 inch nominal and is designed for use in water well systems where backflow prevention and positive shutoff are required between the pump and the distribution line. The female threaded by female threaded end connection makes it compatible with standard NPT piping. Its lead-free construction meets requirements for potable water applications. The LF5100 series is manufactured in the U.S.A. and is available in case quantities of 50 units per carton, making it practical for contractors stocking service vehicles or supply rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free cast silicon bronze body rated for potable water service\u003c\/li\u003e\n  \u003cli\u003ePoppet-style check mechanism with stainless steel spring for reliable backflow prevention\u003c\/li\u003e\n  \u003cli\u003eBuna-N seal provides positive shutoff against reverse flow\u003c\/li\u003e\n  \u003cli\u003e400 psi WOG pressure rating suits residential and light commercial well systems\u003c\/li\u003e\n  \u003cli\u003eFemale threaded by female threaded end connection fits standard NPT piping\u003c\/li\u003e\n  \u003cli\u003eShips complete with spring, washer, and lock nut — no additional trim needed\u003c\/li\u003e\n  \u003cli\u003eMade in U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for residential and light commercial water well systems using 3\/4 inch NPT threaded piping.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or water well contractor in accordance with applicable local plumbing codes and IPC guidelines.
