Wilkins 112-NR3XLDU Pressure Reducing Valve 1-1/2 in Fnpt

Product Description

The WILKINS 112-NR3XLDU is a pressure reducing valve with an integral by-pass check valve and strainer, designed to regulate downstream water pressure in potable water and hydronic systems. Built with a cast bronze body, it handles inlet pressures and delivers a regulated outlet range of 25 to 75 psi. The double union FNPT end connections at 1-1/2 inches allow for in-line removal without cutting pipe, which reduces service time considerably. The integrated strainer protects the valve seat from particulate debris, and the built-in by-pass check valve prevents backflow during pressure fluctuations. Licensed plumbers and mechanical contractors are the primary installers of this valve type.

This valve is suited for residential and light commercial plumbing systems where supply pressure must be reduced to protect downstream fixtures, appliances, and piping. Typical installation locations include the main domestic water service entry point, booster pump discharge lines, and hydronic heating system fill connections. The 1-1/2-inch double union configuration is commonly specified in applications where periodic valve maintenance or replacement without full system drain-down is a priority.

Key Features

• Adjustable outlet pressure range of 25 to 75 psi for flexible system tuning
• Integral by-pass check valve helps prevent reverse flow during pressure transients
• Built-in strainer protects valve internals from sediment and debris
• Double union FNPT connections at 1-1/2 inches allow in-line serviceability without pipe cutting
• Cast bronze body provides durability and corrosion resistance in wet service environments

Compatibility

Designed as an OEM-style replacement or new-installation pressure reducing valve for 1-1/2-inch FNPT potable water and hydronic plumbing systems requiring adjustable downstream pressure control.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable local plumbing code and IPC requirements. Shut off the main water supply and relieve system pressure before removing any existing valve or making new connections. Flow direction must be observed as marked on the valve body. After installation, adjust the pressure setting gradually and verify downstream pressure with a calibrated gauge before returning the system to service.
