Description
Product Overview
The Zurn 3/4 inch NR3XL pressure reducing valve is engineered for demanding industrial environments where precise pressure control and durability are non‑negotiable. Constructed from a premium copper body with a stainless‑steel exterior finish, the valve resists corrosion, scaling, and wear even when exposed to aggressive water or chemical media. The NR3XL model incorporates a cartridge‑loaded mechanism that isolates the internal regulating element, allowing technicians to replace or service the cartridge without disassembling the entire valve assembly. This design reduces service time, minimizes the risk of contaminating the flow path, and extends the overall service life of the unit.
Key dimensions of 5.5 x 2.8 x 5.5 inches make the valve compact enough to fit into confined spaces while still providing a robust 3/4 inch inlet and outlet size. The dual female‑female NPT (National Pipe Thread) connections ensure a secure, leak‑free seal that meets ASSE 1003, CSA B356, and IAPMO standards. The integrated stainless‑steel strainer screen captures debris before it reaches the regulating cartridge, protecting performance and reducing the frequency of maintenance cycles.
Usage
Designed for a broad range of applications, this pressure regulator excels in commercial plumbing, industrial hydraulic circuits, water‑treatment plants, and HVAC systems where consistent pressure is essential for equipment longevity and operational efficiency. The valve’s compact footprint allows installation in tight mechanical rooms, under‑floor plenums, or within prefabricated pipe racks without sacrificing performance. Its 3/4 inch port size is compatible with standard copper, CPVC, PEX, and stainless‑steel tubing, providing flexibility for retrofits and new construction projects alike.
In water‑distribution networks, the Zurn NR3XL maintains downstream pressure within tight tolerances, protecting downstream fixtures from pressure spikes and reducing water hammer. In hydraulic systems, the valve stabilizes pressure to protect pumps, actuators, and seals from over‑pressurization, thereby extending the life of costly components. The valve’s ability to operate reliably in temperatures ranging from freezing conditions to high‑temperature industrial processes makes it a versatile choice for both indoor and outdoor installations.
Why Choose Us
When selecting a pressure regulator, reliability, serviceability, and compliance are paramount. Zurn Industries brings over a century of expertise in fluid control, and the NR3XL model reflects that heritage through rigorous testing, certification, and quality assurance processes. The valve meets NSF/ANSI 61 standards for safe drinking water applications, ensuring that it does not leach harmful substances into the water stream.
Our commitment to customer satisfaction extends beyond the point of sale. Each valve ships with a detailed installation guide, a full set of technical drawings, and access to Zurn’s technical support team, which can assist with sizing, installation, and troubleshooting. In addition, the cartridge‑loaded design means that field service technicians can replace the regulating element in minutes, reducing labor costs and system downtime.
Because the valve is listed under ASSE 1003 and CSA B356, it qualifies for use in jurisdictions that require third‑party certification, simplifying the approval process for engineers and contractors. The combination of a corrosion‑resistant exterior, a high‑quality internal strainer, and a precision‑machined cartridge ensures that the NR3XL delivers consistent performance for years, even in the most demanding environments.
