Legend Valve 752T01N Brass Swing Check Valve 0.5 in Sweat

Product Description

The LEGEND VALVE 752T01N is a brass swing check valve designed to allow one-directional flow and prevent backflow in copper piping systems. It connects via a sweat (SWT) end connection, making it compatible with standard soldered copper tube assemblies. At 0.43 pounds, this compact valve is sized at 0.5 inches and is a reliable choice for residential and light commercial plumbing, hydronic heating, and potable water applications. Licensed plumbers and pipefitters install this type of check valve where backflow prevention is required without the use of an external actuator or spring-assisted disc.

This valve is suited for 0.5-inch copper piping systems in residential and light commercial installations. Typical applications include domestic water supply lines, boiler feed and return circuits, and general plumbing distribution systems where gravity-assisted backflow prevention is appropriate. The swing-disc design operates passively — flow pressure opens the disc, and reverse pressure or gravity closes it, making it a straightforward, low-maintenance solution in horizontal or vertical upward-flow orientations.

Key Features

• Brass body construction for durability and corrosion resistance in water service
• Swing-disc design provides passive, tool-free backflow prevention
• Sweat (SWT) end connections for soldered copper tube installation
• Compact 0.5-inch size suited for residential and light commercial piping
• Lightweight at 0.43 pounds for easy handling and installation in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation swing check valve for 0.5-inch copper sweat piping systems in residential and light commercial plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local plumbing code requirements. Shut off the water supply and fully depressurize and drain the line before soldering. Observe the flow-direction arrow marked on the valve body during installation to ensure proper orientation. Avoid overheating the valve body during the sweat soldering process, as excessive heat can damage internal seating components.
