In its unactuated state, flow passes normally open through ports 1 and 2, making it suitable for fail-open applications where flow must continue during power loss. The aluminum body keeps weight low while the Buna-N seal provides reliable resistance to a broad range of media. Operating pressure ranges from 20 psi to 145 psi, and the maximum working temperature is 120 degrees F. A licensed technician or qualified mechanic typically installs this valve in pneumatic, hydraulic, or process-control lines.\u003c\/p\u003e\n\u003cp\u003eThis valve fits residential and light commercial applications where a compact, 1\/4 inch NPT normally open solenoid is required. Typical install scenarios include HVAC controls, fluid handling panels, and automated process lines. The normally open configuration through ports 1 and 2 makes it well suited for safety-critical circuits that require unrestricted flow when the coil is de-energized. Note that solenoid coils are not included and must be ordered separately to complete the assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNormally open through ports 1 and 2 in unactuated state — supports fail-open circuit designs\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT port size for direct threaded installation into standard pipe fittings\u003c\/li\u003e\n  \u003cli\u003eAluminum body construction reduces overall assembly weight\u003c\/li\u003e\n  \u003cli\u003eBuna-N seal material compatible with a wide range of fluids and gases\u003c\/li\u003e\n  \u003cli\u003eOperating pressure range of 20 psi to 145 psi\u003c\/li\u003e\n  \u003cli\u003eCoil included with valve body; solenoid coils are not included and must be sourced separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation solenoid valve for 1\/4 inch NPT normally open pneumatic, hydraulic, and fluid-control systems requiring an aluminum body and Buna-N seals.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician or licensed pipefitter familiar with the system media and pressure requirements. Depressurize and de-energize the system completely before removing or installing the valve. Apply appropriate thread sealant to NPT connections and avoid over-tightening, which can crack the aluminum body. Verify that the coil assembly is compatible and properly rated before energizing the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Solenoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnactuated State\u003c\/strong\u003e: Normally Open Through Ports 1 and 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Pressure\u003c\/strong\u003e: 20 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Factor (NC)\u003c\/strong\u003e: 1.4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 120 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Included\u003c\/strong\u003e: Yes (solenoid coils not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B511BCNXXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544560730418,"sku":"B511BCNXXC","price":232.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ae853941d286625cbaaf32bc37c0761.jpg?v=1785929933","url":"https:\/\/voomisupply.com\/products\/parker-b511bcnxxc-solenoid-valve-1-4-inch-npt-normally-open","provider":"Voomi Supply","version":"1.0","type":"link"}
