The assembly shall be installed with sufficient side clearance for testing and maintenance. The Model 500XL may be installed in any position. If installed in a pit, vault, or inside application, specify the \"SC\" sealed cage option. Multiple installations are recommended for wide demand variations or where the desired pressure reduction is more than 3 to 1 (i.e.: 150 psi inlet reduced to 50 psi outlet). Anytime a reducing valve is adjusted, a pressure gauge must be used downstream to verify correct pressure setting.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eStandards Compliance:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"background: #f8f9fb; border-left: 4px solid #1d85af; padding: 12px 14px; margin: 0; line-height: 1.7; color: #333;\"\u003eASSE Listed 1003; cUPC Listed; CSA Certified B356; City of Los Angeles Approved; NSF\/ANSI\/CAN 61; NSF\/ANSI\/CAN 372\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eFeatures \u0026amp; Benefits:\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Expansion Protection:\u003c\/strong\u003e Integral by-pass check valve prevents excessive system pressure buildup caused by thermal expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced Piston Design:\u003c\/strong\u003e Provides smooth, responsive reaction to flow demand changes while protecting against inlet pressure variations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free Bronze Y-Strainer:\u003c\/strong\u003e Includes integral YSBR strainer on inlet for debris protection and enhanced system longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Installation:\u003c\/strong\u003e Can be installed in any position with field-adjustable pressure settings from 25-75 psi.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the factory preset pressure for the Zurn 1-500XLYSBR?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The Zurn 1-500XLYSBR comes factory preset at 50 psi and is field adjustable within the 25-75 psi range.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can this valve be installed in a pit or vault application?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Yes, when installed in pits, vaults, or inside applications, specify the \"SC\" sealed cage option for proper protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the maximum pressure reduction ratio recommended for this valve?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: Multiple installations are recommended where the desired pressure reduction exceeds a 3:1 ratio (e.g., 150 psi inlet reduced to 50 psi outlet).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv id=\"W3TucRPBpqQA9ARvwg6ni-content\"\u003e\n\u003cp\u003e\u003cspan\u003e \u003cstrong\u003eNOTICE:\u003c\/strong\u003e Do not use with water that is unsafe or of unknown quality without adequate disinfection either before or after the system. \u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003ci\u003e \"Hydrate Everyone, Everywhere!\" BottleFillingStations.com | \u003ca rel=\"noopener\" href=\"https:\/\/bottlefillingstations.com\/pages\/contact-us\" target=\"_blank\"\u003e Contact us \u003c\/a\u003e \u003c\/i\u003e\u003c\/p\u003e","brand":"Zurn Wilkins","offers":[{"title":"Default Title","offer_id":42914910961727,"sku":"1-500XLYSBR","price":827.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0793\/0985\/files\/500XLYSBR_AF.png?v=1771009068","url":"https:\/\/bottlefillingstations.com\/products\/zurn-wilkins-1-500xlysbr-water-pressure-reducing-valve-with-bypass-check","provider":"BottleFillingStations.com","version":"1.0","type":"link"}
