Hammond 968 Brass Swing Check Valve

The Hammond 968 is a 1 1/2 inch brass swing check valve designed for inline installation. It uses a single-disc swing mechanism to prevent backflow in piping systems. The valve body and seat are constructed from brass for corrosion resistance. It connects via FNPT threaded ends on both sides.

Suits water lines needing a 76 gpm full-flow valve

This valve suits installations requiring a full-flow check valve with a 76 gpm capacity and a cracking pressure between .750 and 1.000 psi. It handles water pressure up to 200 psi at 150 degrees F and operates down to -20 degrees F. It is not rated for steam service, so steam systems should look at alternative valves.

Horizontal or vertical mounting with no extra parts

The valve mounts in either horizontal or vertical orientations without additional accessories. Brass seals are integrated into the body, eliminating separate gasket requirements. No software or electronic components are included with this mechanical valve.
