It operates as a 4-way, 2-position valve with double solenoid actuation and solenoid return, meaning both shifting directions are powered electrically rather than relying on a spring. The valve carries a Cv rating of 1.4 and operates at 120 volts AC. It accepts a 1\/4-inch inlet and 1\/4-inch outlet, and is rated for pressures up to 145 psi. Licensed trades and mechanical contractors install this type of valve in manifold-mounted directional control assemblies.\u003c\/p\u003e\u003cp\u003eThis valve is suited for use in pneumatic control circuits found in light industrial equipment, process automation, and fluid power systems. The stacking design allows multiple valves to be manifold-mounted side by side, reducing plumbing complexity and saving panel space. It is appropriate for both new installations and service replacements on existing stacking manifold assemblies. Operating temperature range runs from 5 degrees F to 120 degrees F, making it suitable for interior mechanical rooms and controlled environments. The NEMA 4 enclosure rating provides protection against wash-down and splashing water.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-way, 2-position directional control with double solenoid actuation\u003c\/li\u003e\n\u003cli\u003eSolenoid return eliminates spring-return dependency for positive bi-directional shifting\u003c\/li\u003e\n\u003cli\u003e1.4 Cv flow rating through 1\/4-inch inlet and outlet ports\u003c\/li\u003e\n\u003cli\u003e120V AC coil voltage for standard industrial power circuits\u003c\/li\u003e\n\u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eNEMA 4 enclosure rating for wet or wash-down environments\u003c\/li\u003e\n\u003cli\u003eStacking body-ported design for manifold assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for stacking pneumatic or fluid power manifold systems that accept 4-way body-ported solenoid valves with 1\/4-inch porting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified fluid power technician or licensed mechanical contractor. De-energize the control circuit and relieve all system pressure before removing or installing any valve. Verify that manifold port alignment and electrical coil voltage match the application requirements before energizing. Follow applicable NFPA and local mechanical codes for pneumatic control system service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Design\u003c\/strong\u003e: 4-Way Body Ported\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Double Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Type\u003c\/strong\u003e: Solenoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 1.4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120V AC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 5 degrees F (-15 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 120 degrees F (49 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Classification\u003c\/strong\u003e: NEMA 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.51 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: B521BB553C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540726612274,"sku":"B521BB553C","price":433.33,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28545b0c0ca05053ceb8220edc5ebeb7.jpg?v=1785863091","url":"https:\/\/voomisupply.com\/products\/parker-b521bb553c-stacking-solenoid-valve-4-way-120v","provider":"Voomi Supply","version":"1.0","type":"link"}
