Wilkins 1-NR3XLDUPEX1 Pressure Reducing Valve 1 in Pex

Product Description

The WILKINS 1-NR3XLDUPEX1 is a 1-inch NR3XL series pressure reducing valve (PRV) configured with double union crimp PEX connections for direct integration into PEX-piped water supply systems. This valve automatically reduces incoming main line pressure to a safe, steady downstream level, protecting fixtures, appliances, and piping from pressure-related damage. The double union design allows the valve body to be removed from the line without cutting pipe, streamlining service and replacement. Licensed plumbers install this valve in residential and light commercial potable water systems where supply pressure must be controlled at the point of entry or at individual zones.

This PRV is suited for installations where PEX tubing is the primary supply pipe material. The crimp PEX end connections allow direct termination to 1-inch PEX lines using standard crimp rings and a calibrated crimp tool, eliminating the need for threaded adapters or transition fittings. Typical applications include whole-house pressure regulation at the service entry, booster system outlets, and zone isolation on multi-family or light commercial plumbing systems. The double union configuration is especially practical in mechanical rooms and tight chases where future valve removal must be fast and clean.

Key Features

• NR3XL series pressure reducing valve rated for potable water service
• 1-inch double union crimp PEX connections for tool-based, leak-resistant termination to PEX tubing
• Double union body allows in-line removal and reinstallation without cutting pipe
• Automatic downstream pressure regulation protects fixtures and appliances
• Lead-free (LF) construction suitable for potable water applications

Compatibility

Designed as an OEM-style replacement or new-installation PRV for 1-inch PEX plumbing systems requiring inline pressure regulation at residential or light commercial service entries.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the main water supply and relieve system pressure before removing any existing valve or making new connections. Use a calibrated crimp tool and the correct crimp ring size for 1-inch PEX to ensure a leak-free connection. Verify downstream pressure with a gauge after startup and adjust the valve setpoint as needed per the manufacturer instructions.
