Wilkins 112-500XL Pressure Reducing Valve 1-1/2 in Fnpt

Product Description

The WILKINS 112-500XL is a pressure reducing valve with an integral bypass check valve, designed for installation in potable water and plumbing distribution systems where downstream pressure control is required. Built with a cast bronze body rated to 300 psi, this valve reduces high inlet pressure to a safe, stable working level while the built-in bypass check valve prevents backflow from thermal expansion on the downstream side. At 1-1/2 inches nominal size with FNPT union inlet and FNPT outlet end connections, it is suited for commercial and light industrial plumbing applications. Licensed plumbers and mechanical contractors are the primary installers of this type of valve.

This valve is appropriate for use in residential and commercial water service applications where both pressure regulation and thermal expansion protection are required in a single device. The union end connections simplify removal and reinstallation during service without disturbing adjacent piping. It is typically installed on the building-side of a water meter or at the point of entry where municipal supply pressure exceeds the safe working range of the internal distribution system.

Key Features

• Integral bypass check valve addresses thermal expansion without requiring a separate device
• Cast bronze body rated to 300 psi for durability in pressurized water systems
• 1-1/2 inches nominal size with FNPT union x FNPT end connections for straightforward installation and serviceability
• Domestic manufacture

Compatibility

Designed as an OEM-style pressure reducing valve for residential and commercial potable water plumbing systems requiring 1-1/2 inch FNPT union connections and integrated bypass check valve functionality.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the main water supply and relieve system pressure before beginning work. The union end connections allow the valve body to be removed without cutting pipe, which is important for future servicing. Do not exceed the rated inlet pressure of 300 psi during pressure testing or operation.
