Legend Valve 105-308 Y-pattern Check Valve 2 in Fnpt

Product Description

The LEGEND VALVE 105-308 is a 2-inch Y-pattern check valve designed to allow one-directional flow and prevent backflow in plumbing and piping systems. Built with a bronze body, this valve connects via female NPT (FNPT) threads on both ends and meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards. The Y-pattern design reduces flow restriction compared to swing-check configurations, making it a practical choice in systems where pressure drop is a concern. Licensed plumbers and pipefitters typically specify this type of valve in commercial and residential water supply, heating, and mechanical piping systems.

This valve is suited for 2-inch pipe installations requiring a threaded inline check valve. Its FNPT x FNPT end connections make it straightforward to install into existing threaded piping without adapters. Common applications include domestic water supply lines, hydronic heating systems, and general mechanical piping where reverse flow protection is required. The bronze body provides corrosion resistance appropriate for potable water and hydronic applications.

Key Features

• Y-pattern body design reduces pressure drop across the valve compared to standard swing-check configurations
• Bronze body construction offers corrosion resistance for water and hydronic service
• FNPT x FNPT connections on both ends for straightforward threaded installation
• Meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards
• 2-inch pipe size suits a wide range of commercial and residential mechanical systems

Compatibility

Designed as an OEM-style threaded check valve for 2-inch FNPT piping systems in residential and commercial plumbing and hydronic heating applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IPC guidelines. Shut off and depressurize the water or fluid system completely before removing or installing the valve. Apply appropriate thread sealant or PTFE tape to male threads before making up connections, and verify flow direction arrow on the valve body is oriented correctly in the line. Do not overtighten threaded connections into the bronze body.
