Legend Valve 105-307 Y-pattern Check Valve 1-1/2 in

Product Description

The LEGEND VALVE 105-307 is a Y-pattern check valve designed to allow one-directional flow and prevent backflow in plumbing and hydronic piping systems. Built with a bronze body and FNPT x FNPT end connections, it is suited for installations where a low-profile, inline check valve is required. The Y-pattern body configuration provides reduced turbulence and pressure drop compared to swing-style designs. At 1-1/2 inches pipe size, it fits standard residential and light commercial piping. Licensed plumbers and pipefitters are the typical installers for this type of valve.

This check valve is appropriate for use in domestic water supply, hydronic heating, and general plumbing distribution systems. The FNPT x FNPT connection type makes it compatible with standard threaded pipe installations, simplifying integration into existing systems. It is commonly used in mechanical rooms, boiler rooms, and utility piping where backflow prevention is required without the need for a dedicated bypass or external actuator.

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-1/2 inch 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 local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male threads per standard practice before making up FNPT connections. Verify flow direction markings on the valve body before final assembly to ensure correct orientation.
