It features 1\/4 inch NPT inlet and outlet ports and a Cv rating of 0.83, making it suited for controlling pneumatic or hydraulic actuators in industrial and commercial applications. The valve shifts when the button is depressed and returns to its original position via an internal spring when pressure is released. It is installed by fluid power technicians, automation specialists, and maintenance trades working with compressed air or compatible fluid systems.\u003c\/p\u003e\u003cp\u003eThis valve is commonly used in industrial automation, machine tool, and process control applications where a compact, manually triggered directional shift valve is required. Its 5-port configuration supports standard 4-way circuit routing. With a working pressure range of 0 to 150 psi and a temperature range of 32 to 175 degrees F, it fits a wide variety of light-to-medium duty pneumatic control circuits in both production and maintenance environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-way, 2-position directional control for pneumatic circuit applications\u003c\/li\u003e\n\u003cli\u003eButton-spring return actuator provides momentary manual actuation\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT inlet and outlet ports for standard pipe thread connections\u003c\/li\u003e\n\u003cli\u003eCv rating of 0.83 for consistent, predictable flow control\u003c\/li\u003e\n\u003cli\u003e5-port design supports full 4-way directional circuit configurations\u003c\/li\u003e\n\u003cli\u003eOperating range of 0 to 150 psi and 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 new-installation directional control valve for pneumatic systems using 1\/4 inch NPT porting and operating within 0 to 150 psi working pressure limits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified fluid power technician or maintenance professional familiar with pneumatic directional control circuits. Depressurize and lock out the pneumatic system before removing or installing any valve. Ensure all NPT thread connections are properly sealed with thread sealant compatible with the system media. Verify that system operating pressure and temperature do not exceed the rated limits of this valve before returning the system to service.\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: Button-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\u003eInlet Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 0.83\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: 520411000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541115175218,"sku":"520411000","price":363.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/59c863169f05fd16873e3d0333fe8fe1.jpg?v=1785868636","url":"https:\/\/voomisupply.com\/products\/parker-520411000-4-way-2-position-valve-1-4-inch-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
