Wilkins NR3XLDUC-34 NR3XL Pressure Reducing Valve with Integral By-pass Check Valve and Strainer 3/4 Inch Double Union Fnpt X Female C Union

Product Description

The Wilkins NR3XLDUC-34 is a 3/4 inch lead-free pressure reducing valve from the NR3XL series. It is designed for residential and light commercial plumbing systems where stable downstream water pressure is required. This valve reduces high incoming supply pressure to a safe, preset level, protecting fixtures, appliances, and piping from pressure damage. It also features an integral by-pass check valve and a built-in strainer, combining three functions into one compact unit. The by-pass check valve prevents backflow from thermal expansion, which is a critical requirement in closed water systems. The strainer catches debris before it reaches the valve seat, extending service life and reducing maintenance calls. The body is cast bronze, a material well proven in potable water applications for its corrosion resistance and long-term durability. The stem is brass and the spring is 302 stainless steel, both chosen for strength and resistance to water exposure. Seals and elastomers are Buna Nitrile and EPDM, compatible with standard municipal water supply. The end connections are double union FNPT x Female C Union, allowing the valve to be removed from the line without cutting pipe. This double union configuration speeds up installation and future serviceability, which plumbing contractors and maintenance technicians appreciate in tight mechanical rooms. The valve is rated to 400 psi and handles water temperatures up to 140 degrees Fahrenheit. Overall height is 6-1/4 inches and inlet to outlet length is 5-3/8 inches, keeping the installed footprint manageable. The NR3XLDUC-34 is a practical, code-conscious choice for any plumber installing or replacing a PRV in a 3/4 inch water supply line.

• Integral by-pass check valve controls thermal expansion in closed plumbing systems
• Built-in strainer protects valve components and downstream fixtures from debris
• Double union end connections allow in-line removal without cutting pipe

Product Highlights

The Wilkins NR3XLDUC-34 combines pressure reduction, by-pass check, and straining into a single 3/4 inch lead-free bronze valve. Double union connections make installation and future service faster and easier for trade professionals.
