American Granby lf5100-3/4 Bronze Check Valve 3/4 Inch

Product Description

The AMERICAN GRANBY lf5100-3/4 is a lead-free, poppet-style check valve built for water well system applications. 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.

This 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.

Installation Notes

Installation should be performed by a licensed plumber or water well contractor in accordance with applicable local plumbing codes and IPC guidelines. Shut off and relieve pressure from the water system before removing or installing any valve. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten the threaded connections, as silicon bronze fittings can be damaged by excessive torque.
