Brass swing check valve for residential plumbing

This ZORO SELECT 10F329 valve uses a brass body and an inline swing mechanism to allow flow in one direction while preventing backflow. It suits hot and cold water lines in residential and light-commercial systems where a simple, reliable check is required.

Sweat-to-sweat connections suit copper pipe

The 3/4 in sweat ends are soldered directly to copper tubing, creating a permanent, leak-resistant joint without threads or adapters. Brass seat and seal materials match the body for consistent corrosion resistance, and the valve mounts in horizontal or vertical orientations to fit existing pipe runs.

Operates between -20 and 180 Degrees F

Cracking pressure ranges from .750 to 1.000 psi, so the disc opens with minimal flow and closes positively when flow stops. Full-flow design delivers 20 gpm without restriction, and the 125 psi steam rating covers low-pressure steam applications. No moving parts beyond the swing disc keep maintenance low.

Questions about this item

What pressure does the 0.750 to 1.000 psi cracking pressure actually hold back before the swing check opens?

The valve begins to open between 0.750 and 1.000 psi differential, so it will hold back any pressure below roughly three-quarters of a pound before allowing flow.

What copper pipe size and joint type does the 3/4" sweat connection require?

It fits 3/4 inch nominal copper tube and needs a soldered sweat joint on each end; no threads or compression fittings are used.

How do I orient the valve during soldering so the swing mechanism works afterward?

Install with the flow arrow pointing in the direction of flow; the hinge pin must sit horizontally whether the pipe runs horizontal or vertical, otherwise the disc will not seal.
