Legend Valve 105-306 Y-pattern Check Valve 1-1/4 in

Product Description

The LEGEND VALVE 105-306 is a 1-1/4 inch Y-pattern check valve with FNPT x FNPT end connections and a bronze body construction. Check valves of this type allow flow in one direction only, preventing backflow in pressurized piping systems. The Y-pattern design provides a straighter flow path compared to swing or ball check configurations, which reduces pressure drop across the valve. This valve is installed by licensed plumbers in water distribution, heating, and mechanical piping systems. The bronze body offers corrosion resistance suited to water service applications. It meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards.

The 105-306 is appropriate for residential and light commercial plumbing and hydronic heating applications where backflow prevention is required in a 1-1/4 inch pipeline. Typical installation scenarios include domestic water supply lines, boiler makeup water lines, and recirculation systems. The FNPT x FNPT connection type allows direct threaded installation into standard NPT-tapped fittings or piping without adapters. This valve is suited for use in systems where flow direction control is a code or system design requirement.

Key Features

• Y-pattern body design reduces flow restriction and pressure drop compared to standard check valve configurations
• Bronze body construction provides corrosion resistance for potable water and hydronic service
• FNPT x FNPT connections on both ends for straightforward threaded installation
• 1-1/4 inch pipe size fits standard NPT piping without adapters
• Meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards for threaded pipe fittings and bronze fittings

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 1-1/4 inch FNPT threaded piping systems in residential and commercial plumbing and hydronic heating applications.

Installation Notes

Installation is performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off system pressure and drain the line before removing any existing valve or fitting. Apply thread sealant or PTFE tape to male NPT threads before making up connections. Verify flow-direction arrow on the valve body is oriented correctly with system flow before final makeup.
