Actuated by a pedal with spring return, it shifts position when the pedal is depressed and automatically returns when released. The valve features a Cv rating of 0.83 and handles working pressures from 0 to 150 psi. With a 5-port configuration and 1\/4 inch NPT inlet and outlet connections, it is built for reliable directional control in industrial and manufacturing environments. Licensed pneumatic system technicians and maintenance mechanics are the typical installers of this component.\u003c\/p\u003e\u003cp\u003eThis valve is suited for applications where foot-operated control of pneumatic actuators or cylinders is required, freeing the operator's hands during the work cycle. It fits into stationary pneumatic circuits found in light industrial machinery, assembly equipment, and production line tooling. The 1\/4 inch NPT port sizing is common in bench-top and small-bore pneumatic systems operating at shop air pressures up to 150 psi. Its spring-return mechanism ensures the valve defaults to its original position when foot pressure is removed, providing a built-in fail-to-default behavior appropriate for safety-conscious installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-way, 2-position directional control valve with 5-port configuration\u003c\/li\u003e\n\u003cli\u003ePedal actuator with spring return for hands-free, foot-operated control\u003c\/li\u003e\n\u003cli\u003eCv rating of 0.83 for consistent pneumatic flow performance\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT inlet and outlet ports for standard shop-air piping\u003c\/li\u003e\n\u003cli\u003eOperating pressure range of 0 to 150 psi\u003c\/li\u003e\n\u003cli\u003eTemperature range of 32 to 175 degrees F for typical indoor industrial environments\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 connections and operating within 0 to 150 psi pressure ranges.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pneumatic systems technician or industrial maintenance mechanic. Depressurize the pneumatic circuit and lock out the compressed air supply before removing or installing the valve. Ensure all NPT threads are sealed with appropriate thread sealant tape or compound rated for pneumatic service. Verify that system operating pressure and temperature remain within the valve's rated limits 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: Pedal-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 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\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: 520711000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538937348402,"sku":"520711000","price":424.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14a0af699ec4142600c642a7d7f2e7b5.jpg?v=1785830216","url":"https:\/\/voomisupply.com\/products\/parker-520711000-4-way-2-position-valve-pedal-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
