In its unactuated state, flow passes normally open through ports 1 and 2. The valve body is constructed from aluminum and uses a Buna-N seal for compatibility with a broad range of media. It is rated for a maximum working pressure of 145 psi and a minimum of 20 psi, with a maximum operating temperature of 120 degrees F. This is a valveless-coil design, meaning solenoid coils are not included and must be sourced separately. HVAC technicians, automation contractors, and industrial service professionals are the typical installers.\u003c\/p\u003e\u003cp\u003eThis valve is suited for residential and light commercial applications where a 2-position directional control is needed in pneumatic systems, HVAC controls, or fluid handling circuits. The 1\/4 inch port size makes it appropriate for compact plumbing arrangements common in zone control and process automation setups. The normally open configuration through ports 1 and 2 is useful in fail-safe designs where flow must continue if power is lost.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble solenoid, 2-position valveless-coil design — coils ordered separately\u003c\/li\u003e\n\u003cli\u003eNormally open through ports 1 and 2 in unactuated state\u003c\/li\u003e\n\u003cli\u003e1\/4 inch port size for compact plumbing installations\u003c\/li\u003e\n\u003cli\u003eAluminum body for lightweight, corrosion-resistant construction\u003c\/li\u003e\n\u003cli\u003eBuna-N seal for compatibility with a wide range of fluids and gases\u003c\/li\u003e\n\u003cli\u003eOperating pressure range: 20 to 145 psi\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style directional control valve for pneumatic and fluid control systems requiring a 2-position double solenoid configuration with a 1\/4 inch port.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic or fluid control systems. Depressurize the system and shut off all power before servicing or replacing the valve. Solenoid coils are not included and must be matched and installed separately before the valve will actuate. Verify port connections and flow direction against system schematics before applying pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Double Solenoid 2-Position Valveless Coil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/4 inch\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\u003eCv Factor (NC)\u003c\/strong\u003e: 1.4\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\u003eMaximum Operating 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\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: B521BCNXXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540611989810,"sku":"B521BCNXXC","price":349.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/526ceaeadc25f3477c0cb65ab3be90f7_e0bdcbdc-f898-419a-bda5-9a11c5a4a4f8.jpg?v=1785860053","url":"https:\/\/voomisupply.com\/products\/parker-b521bcnxxc-double-solenoid-valve-1-4-inch-port","provider":"Voomi Supply","version":"1.0","type":"link"}
