The valve carries a Cv rating of 5.0 and is configured normally open, meaning it returns to the open position on power loss via the spring return mechanism. Trim is stainless steel throughout, and the body is pressure-rated to 300 psi. This assembly is designed for zone isolation and flow control in hydronic systems and is typically installed by licensed HVAC and plumbing technicians.\u003c\/p\u003e\u003cp\u003eThis valve assembly is suited for residential and light commercial hydronic systems handling chilled or hot water, including glycol solutions up to 50 percent concentration. The normally open configuration makes it appropriate for applications where a fail-open condition is required on loss of power. The equal percentage flow characteristic provides precise modulation across a range of load conditions, making it a common choice for zone control in fan coil, air handler, and radiant loop applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-way, normally open valve returns to open position on power loss via spring return\u003c\/li\u003e\n\u003cli\u003eCv 5.0 with equal percentage flow characteristic for consistent zone flow control\u003c\/li\u003e\n\u003cli\u003e3\/4-inch NPT internal thread fitting for standard threaded pipe connections\u003c\/li\u003e\n\u003cli\u003eStainless steel trim rated for chilled or hot water and up to 50 percent glycol solutions\u003c\/li\u003e\n\u003cli\u003eBody pressure rating of 300 psi for compatibility with a wide range of hydronic system pressures\u003c\/li\u003e\n\u003cli\u003eAC 24-volt on\/off control signal for straightforward integration with standard zone controllers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style zone valve assembly for 3\/4-inch NPT hydronic piping systems requiring AC 24-volt on\/off spring return actuator control in normally open configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with applicable mechanical codes. Shut off system water flow and relieve line pressure before removing or installing the valve assembly. Ensure the actuator wiring is connected to a properly fused 24-volt AC control circuit before energizing. Do not exceed the rated body pressure of 300 psi or use fluids outside the specified glycol concentration limit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Pattern\u003c\/strong\u003e: 2-way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 5.0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Fitting\u003c\/strong\u003e: NPT Internal Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Characteristic\u003c\/strong\u003e: Equal percentage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFluid Compatibility\u003c\/strong\u003e: Chilled or hot water, up to 50% glycol\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Pressure Rating\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrim Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Signal\u003c\/strong\u003e: On\/Off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Voltage\u003c\/strong\u003e: 24 volts AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Spring Return\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFail Position\u003c\/strong\u003e: Normally Open\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BELIMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: zone220n-50+zone24no\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELIMO","offers":[{"title":"Default Title","offer_id":51467649089842,"sku":"ZONE220N-50+ZONE24NO","price":241.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945793.jpg?v=1783909325","url":"https:\/\/voomisupply.com\/products\/belimo-zone220n-50-zone24no-zone-valve-0-75-in-npt-cv-5","provider":"Voomi Supply","version":"1.0","type":"link"}
