Legend Valve 105-305 Y-pattern Check Valve 1 in Fnpt Bronze

Product Description

The LEGEND VALVE 105-305 is a Y-pattern bronze check valve designed for one-way flow control in plumbing and piping systems. The Y-pattern body geometry reduces pressure drop compared to swing-check designs, making it well suited for systems where flow efficiency matters. Connections are female NPT on both ends, conforming to ANSI/ASME B1.20.1 thread standards. The bronze body construction resists corrosion in potable water, hydronic heating, and light commercial fluid systems. Licensed plumbers and pipefitters are the primary installers of this valve type.

This check valve is used in residential and light commercial plumbing applications where backflow prevention is required without a shutoff function. Typical install scenarios include domestic water supply lines, boiler makeup water lines, and recirculation systems. The FNPT x FNPT end connections allow direct threaded installation into standard iron pipe size fittings and fixtures on a 1 inch pipe line.

Key Features

• Y-pattern body reduces inline pressure drop compared to standard swing-check designs
• Bronze body construction for corrosion resistance in water and hydronic applications
• FNPT x FNPT connections on both ends for straightforward threaded installation
• Meets ANSI/ASME B1.20.1 thread standard and ANSI/ASME B16.18 cast copper alloy fitting standard
• 1 inch pipe size fits standard residential and light commercial line sizes

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1 inch FNPT threaded piping systems in residential and light commercial 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 before removing any existing valve or making new connections. Apply thread sealant or PTFE tape to male threads per standard practice before making up the FNPT connections. Verify flow direction marking on the valve body before completing the installation.
