American Granby lf5100-1/2 Bronze Check Valve 1/2in

Product Description

The AMERICAN GRANBY lf5100-1/2 is a lead-free, cast silicon bronze poppet check valve designed for water well system applications. It controls flow direction by allowing fluid to pass in one direction while preventing backflow through a spring-loaded poppet mechanism. The body is rated at 400 psi WOG, making it suitable for demanding well pump installations. The stainless steel spring and Buna-N seal deliver reliable shutoff performance in fresh water service. Licensed plumbers and water well contractors install this valve as part of residential and light commercial well system piping assemblies.

This valve is sized at 1/2 inch with female threaded connections on both ends, fitting standard NPT-threaded pipe common in water well drop pipe, pressure tank lines, and pump discharge assemblies. Its lead-free silicon bronze construction meets requirements for potable water installations where lead-free materials are mandated. The included spring, washer, and lock nut ship with each valve, reducing the need for separate hardware on the job. This valve is manufactured in the U.S.A.
