The end switch closes when the valve opens, so it can be used to enable the boiler or zone circulator. Field wiring lands on a screw terminal block on the actuator. The press-connection body installs with a copper press tool, with no soldering at the valve. This model is rated for a 2.5 Cv flow capacity and a maximum fluid temperature of 240°F.\u003c\/p\u003e\u003cp\u003eBefore ordering: confirm that the 1\/2\" press connection matches your piping, that the control circuit is 24V, and that the zone valve is meant to stay closed without power (normally closed).\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 Z54P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e Z-One\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e 2-Way Zone Valve, Normally Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1\/2\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Press\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Capacity (Cv):\u003c\/strong\u003e 2.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Temperature:\u003c\/strong\u003e 240°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Switch:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Screw terminal block\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 8016615551082\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e 2-Way Zone Valve\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\/Z54P_CALE-Z54P_8016615551082_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\/Z54P_CALE-Z54P_8016615551082_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\/Z54P_CALE-Z54P_8016615551082_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\/Z54P_CALE-Z54P_8016615551082_Sell.pdf\" target=\"_blank\" rel=\"noopener\"\u003eProduct Brochure\u003c\/a\u003e (PDF)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee also: \u003ca href=\"\/collections\/2-way-zone-valve\"\u003e2-way zone valve\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":50517449015399,"sku":"CALE-Z54P","price":239.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2253\/3479\/files\/Z54P_CALE-Z54P_8016615551082.jpg?v=1792424502","url":"https:\/\/www.thehousesupplier.com\/products\/caleffi-z54p-z-one-2-way-zone-valve-normally-closed-terminal-block-with-micro-switch-1-2-press-2-5-cv-24v","provider":"The House Supplier","version":"1.0","type":"link"}
