{"product_id":"zurn-12-nr3xldulup","title":"Zurn 12-NR3XLDULUP 1\/2\" Water Pressure Reducing Valve, Lead-Free Bronze, FNPT","description":"\u003cp\u003eThe Zurn Wilkins 12-NR3XLDULUP is a 1\/2\" pressure reducing valve with FNPT connections. It reduces inlet pressure of up to 400 psi to an adjustable 15-75 psi downstream, factory set at 50 psi. It features a lead-free bronze body. Rated to 400 psi and up to 140°F.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat pressure is it set to out of the box?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003e12-NR3XLDULUP ships factory set at 50 psi. The adjustable reduced-pressure range is 15 to 75 psi, so you can dial the outlet anywhere in that band on site with the adjusting bolt - loosen the locknut, turn to raise or lower pressure, retighten and verify with a downstream gauge.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it include a strainer?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes - 12-NR3XLDULUP has an integral strainer built into the body, so a separate inline strainer ahead of it is not required.

It is not a substitute for a properly sized expansion tank where your local code requires one - the bypass only relieves back to the street when street pressure is lower than the closed-system pressure.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes it come with a gauge?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003e12-NR3XLDULUP has a gauge tapping (port) but ships plugged, with no gauge included.
