Legend Valve 105-109 Inline Check Valve 2.5 in Fnpt Brass

Product Description

The LEGEND VALVE 105-109 is a brass inline check valve designed to allow one-directional fluid flow while preventing backflow in pressurized piping systems. Built with female NPT connections on both ends, it installs directly into standard threaded pipe runs without the need for adapters. The body is machined from brass for durability and corrosion resistance in potable water and general plumbing applications. At 2.5 inches pipe size, this valve suits larger residential and light commercial installations. Licensed plumbers and pipefitters are the primary installers for a fitting of this size and connection type.

This check valve is suited for inline installation in water supply, distribution, and mechanical piping systems where backflow prevention is required. The FNPT x FNPT end connections thread directly onto Schedule 40 or Schedule 80 pipe and standard brass or bronze fittings. Typical applications include water service lines, pump discharge lines, and building mechanical rooms. It is appropriate for both new construction and retrofit projects requiring reliable non-return flow control at the 2.5-inch pipe size.

Key Features

• Brass body construction provides corrosion resistance in water and general plumbing service
• FNPT x FNPT end connections thread onto standard NPT pipe without additional adapters
• 2.5-inch pipe size accommodates higher-flow residential and light commercial applications
• Meets ANSI/ASME B1.20.1 and ANSI/ASME B16.18 standards for threaded pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation check valve for 2.5-inch NPT threaded piping systems in residential and light commercial plumbing 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 completely before threading in the valve. Apply appropriate thread sealant or PTFE tape to the male NPT pipe threads before making up connections. Verify the flow-direction arrow on the valve body is oriented correctly with the intended direction of flow before finalizing the installation.
