The valve uses a lever actuator with spring return, snapping back to its default position when the lever is released. It features a Cv rating of 0.830 and handles working pressures from 0 to 150 psi. Weighing 2 pounds, this valve is sized for compact installations where space and precise flow control are priorities. Licensed pneumatic technicians and industrial maintenance professionals are the primary installers of this type of valve.\u003c\/p\u003e\u003cp\u003eThis valve is suited for use in pneumatic directional control circuits in both light industrial and general automation applications. The 1\/4 inch NPT inlet and outlet ports make it compatible with standard quarter-inch pneumatic lines found in machinery, automated equipment, and process control panels. Its 5-port, 2-position configuration is a common format for actuating double-acting cylinders or directing airflow between two discrete paths. The operating temperature range of 32 to 175 degrees F makes it appropriate for standard indoor industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-way, 2-position directional control with 5-port configuration for double-acting actuator circuits\u003c\/li\u003e\n\u003cli\u003eLever actuator with spring return for hands-free reset to default position upon lever release\u003c\/li\u003e\n\u003cli\u003eCv rating of 0.830 for consistent, metered pneumatic flow\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT threaded inlet and outlet ports for straightforward integration with standard pneumatic lines\u003c\/li\u003e\n\u003cli\u003eOperating pressure range of 0 to 150 psi\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 32 to 175 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install mechanically operated directional control valve for standard 1\/4 inch NPT pneumatic circuits in light industrial and automation systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize the pneumatic circuit fully before removing or installing any valve component. Verify that line pressure does not exceed 150 psi and that ambient temperatures remain within the rated range. Use appropriate thread sealant on NPT connections and avoid overtightening, which can crack valve bodies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Design\u003c\/strong\u003e: 4-Way, 2-Position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Lever-Spring Return\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Type\u003c\/strong\u003e: Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Ports\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 0.830\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\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Pressure\u003c\/strong\u003e: 0 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 32 degrees F (0 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 175 degrees F (80 degrees C)\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: 520811000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540469023026,"sku":"520811000","price":348.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e078c48ce07ef87232ff5894f29abae.jpg?v=1785856190","url":"https:\/\/voomisupply.com\/products\/parker-520811000-4-way-2-position-valve-lever-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
