The body is machined from aluminum for a lightweight, corrosion-resistant build, and the Buna-N seals provide reliable performance across a broad range of compatible media. Operating pressure ranges from 30 psi to 145 psi, making it suited for typical industrial and HVAC control applications. The Cv factor of 1.4 supports moderate flow rates through the valve. A solenoid coil is required for operation but is not included with this valve body — the coil must be ordered separately.\u003c\/p\u003e\u003cp\u003eThis valve is commonly installed in pneumatic control circuits, fluid distribution panels, and automated process systems where positive shutoff at all ports is required in the de-energized state. It is appropriate for residential and light commercial HVAC, refrigeration, and general industrial applications where 1\/4 inch NPT connections are specified. Licensed HVAC technicians, industrial maintenance technicians, and plumbing contractors are the typical installers of this type of valve.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAll-ports-blocked unactuated state ensures positive shutoff when de-energized\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT port size for standard threaded connections\u003c\/li\u003e\n\u003cli\u003eAluminum body construction for lightweight durability\u003c\/li\u003e\n\u003cli\u003eBuna-N seals compatible with a wide range of media\u003c\/li\u003e\n\u003cli\u003eCv factor of 1.4 for consistent, predictable flow performance\u003c\/li\u003e\n\u003cli\u003eSolenoid coil not included — allows selection of coil voltage to match system requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation solenoid valve for pneumatic and fluid control systems requiring a 1\/4 inch NPT, all-ports-blocked configuration with an aluminum body.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic or fluid piping systems. De-energize and depressurize the system fully before removing or installing the valve. Apply thread sealant appropriate to the media and system pressure when making NPT connections, and avoid over-tightening aluminum-bodied fittings. A compatible solenoid coil must be sourced and installed separately before the valve can be electrically actuated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: All Ports Blocked\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Pressure\u003c\/strong\u003e: 30 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\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\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\u003eCoil Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: B551BCNXXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544501649714,"sku":"B551BCNXXC","price":399.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/526ceaeadc25f3477c0cb65ab3be90f7_39c5b208-65f8-4270-8dce-4d2bfdd279fd.jpg?v=1785928299","url":"https:\/\/voomisupply.com\/products\/parker-b551bcnxxc-solenoid-valve-1-4-inch-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
