Legend Valve 105-464 Inline Check Valve 3/4 in Bronze

Product Description

The LEGEND VALVE 105-464 is a 3/4-inch inline check valve designed to prevent backflow in pressurized piping systems. The valve body is constructed from bronze with a nitrile butadiene rubber (NBR) seal and a phosphor-bronze spring, making it well suited for water supply, HVAC hydronic loops, and general plumbing service lines. It connects via soldered joints on both ends and is rated for working pressures up to 250 psi (WOG). Licensed plumbers and mechanical contractors are the primary installers for this valve type in both new construction and retrofit applications.

The 105-464 is intended for inline installation in residential and light commercial piping systems where reverse flow protection is required. Typical applications include domestic water supply lines, hydronic heating and cooling circuits, and irrigation system headers. The soldered end connections suit copper pipe installations common in plumbing and mechanical systems. The bronze body holds up well in wet service environments with treated or potable water.

Key Features

• Bronze body construction for corrosion resistance in wet service environments
• Nitrile butadiene rubber (NBR) seal provides reliable shutoff and long service life
• Phosphor-bronze spring maintains consistent cracking pressure and resists corrosion
• Soldered x soldered end connections for standard copper pipe installation
• Rated to 250 psi WOG for broad compatibility across residential and light commercial pressure ranges
• Meets ISO and MSS SP-80 standards for inline check valve construction

Compatibility

Designed as an OEM-style inline check valve replacement for 3/4-inch copper pipe systems using soldered end connections in plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure fully before cutting into the line or removing an existing valve. Flow direction must be observed during installation — the valve body is marked to indicate proper orientation in the line. Allow solder joints to cool completely and the flux residue to be flushed before returning the system to service.
