Zurn Wilkins 1-NR3XL 1 in Pressure Reducing Valve - Compact

Our review of the Zurn Wilkins 1-NR3XL 1 in Pressure Reducing Valve finds it best suited to plumbers and property managers who need a compact, serviceable regulator for residential and light commercial installs. The single biggest reason to buy is its cartridge-loaded design combined with a stainless steel strainer screen, which makes routine maintenance fast and reduces downtime for systems that see sediment or debris. In short, this valve is a practical, durable choice when tight space and easy servicing are priorities.

Key Features

• Short lay length: The compact design allows installation in tight spaces where a larger valve would not fit, saving time on layout and fittings.
• Cartridge-loaded design: The replaceable cartridge simplifies repairs and service calls by allowing rapid internal access without removing the entire body.
• Multiple tailpiece options: Threaded, PEX, copper sweat and CPVC tailpieces reduce installation time by matching common piping methods on site.
• Stainless steel strainer screen: The integral strainer holds up against corrosion and captures debris to protect downstream plumbing components.
• Corrosion-resistant bell: The threaded bell provides quick access to internals and resists corrosion for longer service life in wet environments.
• Certifications: Listed and certified to industry standards, ensuring it meets common code and potable water requirements.

Who It's For

This valve suits residential plumbers, maintenance technicians, and landscapers installing pressure regulation on single-family and multifamily properties or public entrance systems. Its compact profile and service-friendly cartridge make it especially useful in retrofit jobs and tight mechanical rooms.

Those needing industrial-scale flow capacities or specialty valve functions should look elsewhere; the NR3XL is optimized for residential and light commercial use where routine sediment cleaning and straightforward repairs are typical.
