It reduces high incoming water pressure to a steady, adjustable outlet pressure.\u003c\/p\u003e\u003cp\u003ePressCal valves are ASSE 1003 listed, low-lead, pre-adjustable PRVs for domestic water systems, typically installed on the main water service after the meter to protect fixtures, appliances and piping from excess pressure. The brass body is rated for a maximum pressure of 300 psi.\u003c\/p\u003e\u003cp\u003eBefore ordering: match the PRV to your 1-1\/4\" service line and confirm the female NPT connection. Male threaded nipples or adapters are needed on both sides. If you want to read outlet pressure at the valve, choose a version with a gauge. Check local code for thermal expansion requirements once a PRV is installed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Caleffi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 535370HA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e PressCal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Pressure reducing valve, pre-adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1-1\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet x Outlet:\u003c\/strong\u003e FNPT x FNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure:\u003c\/strong\u003e 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e No gauge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e ASSE 1003\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Content:\u003c\/strong\u003e Low lead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 8016615549317\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Pressure Reducing Valves\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDocuments\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/535370HA_CALE-535370HA_8016615549317_TechB.pdf\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Data Sheet\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/535370HA_CALE-535370HA_8016615549317_Inst.pdf\" target=\"_blank\" rel=\"noopener\"\u003eInstallation \u0026amp; Operation Manual\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/535370HA_CALE-535370HA_8016615549317_Sub.pdf\" target=\"_blank\" rel=\"noopener\"\u003eSubmittal Sheet\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/res.cloudinary.com\/dzhpkjoqj\/Caleffi\/535370HA_CALE-535370HA_8016615549317_Sell.pdf\" target=\"_blank\" rel=\"noopener\"\u003eTechnical Bulletin\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee also: \u003ca href=\"\/collections\/pressure-reducing-valves\"\u003epressure reducing valves\u003c\/a\u003e, \u003ca href=\"\/collections\/caleffi-north-america\"\u003eall Caleffi products\u003c\/a\u003e.\u003c\/p\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":50517454356583,"sku":"CALE-535370HA","price":377.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2253\/3479\/files\/535370HA_CALE-535370HA_8016615549317.jpg?v=1792424672","url":"https:\/\/www.thehousesupplier.com\/products\/caleffi-535370ha-presscal-pressure-reducing-valve-1-1-4-female-npt-asse-1003-low-lead","provider":"The House Supplier","version":"1.0","type":"link"}
