1-Inch Bronze Swing Check Valve

This 1-inch bronze swing check valve uses a sweat-by-sweat connection for inline copper piping. The inline swing mechanism allows flow in one direction while preventing backflow automatically. It is suited for residential and light-commercial plumbing systems requiring a reliable non-return device.

Replaces worn or missing check valves

Install this valve when an existing swing check leaks, chatters or no longer seals at low pressure. The 0.500 to 0.750 psi cracking pressure ensures the disc opens with minimal flow, making the upgrade worthwhile on gravity-fed or low-head circuits where older, stiffer valves stay shut.

Sweat connections need clean copper and flux

Horizontal mounting is required for the swing disc to operate correctly; vertical runs will cause malfunction. Overheating the bronze body during soldering can damage the bronze seal seat, so apply heat evenly and avoid excessive temperatures. Ensure pipe ends are deburred to prevent turbulence at the seat.

Questions about this item

What pipe size and connection type does the 1509 valve need?

The valve fits 1-inch copper pipe with sweat-to-sweat solder connections on both ends.

How is the 1509 valve installed and what orientation mistake should I avoid?

Solder both sweat ends into the horizontal pipe run; the hinge pin must stay on top so the disc swings freely.

When will the bronze seat and disc of the 1509 valve need replacement?

Inspect annually; replace if the bronze disc no longer seals against the bronze seat at the rated 200 psi.
