It features a button-actuated, manual-return mechanism that shifts the valve when pressed and returns to the original position upon release. The valve has a Cv rating of 0.83 and is rated for working pressures from 0 to 150 psi, making it suitable for a wide range of light to medium-duty pneumatic systems. Both the inlet and outlet ports are 1\/4 inch NPT, and the valve has 5 ports total. Licensed fluid power technicians and industrial maintenance mechanics are the primary installers of this type of valve.\u003c\/p\u003e\u003cp\u003eThis valve is suited for industrial machinery, automation equipment, and pneumatic control panels where a mechanically triggered directional shift is required. The button-manual return configuration is a common selection in applications where an operator or mechanical cam must initiate a discrete directional change without requiring an electrical signal. It is appropriate for use in light manufacturing, assembly equipment, and machine tool applications that operate within the rated pressure and temperature range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-way, 2-position directional control for standard pneumatic circuit applications\u003c\/li\u003e\n\u003cli\u003eButton-actuated manual return for operator or cam-triggered control without electrical input\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT inlet and outlet ports for straightforward plumbing into standard pneumatic lines\u003c\/li\u003e\n\u003cli\u003eCv rating of 0.83 supports controlled flow in light to medium-duty circuits\u003c\/li\u003e\n\u003cli\u003eRated 0 to 150 psi working pressure with a 5-port body\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 32 degrees F to 175 degrees F covers most indoor industrial environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for pneumatic directional control circuits requiring a 4-way, 2-position, 5-port mechanically operated valve with 1\/4 inch NPT connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified fluid power technician or industrial maintenance mechanic familiar with pneumatic directional control valves. Depressurize and lock out the pneumatic circuit before removing any existing valve or making new connections. Verify that all port connections match the system schematic before applying pressure, and confirm the circuit does not exceed the 150 psi maximum working pressure rating of this valve.\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-Manual Return\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: 1 pound\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: 520431000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544441258290,"sku":"520431000","price":348.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/032e25d54d8d8373442016a7726894c9.jpg?v=1785926620","url":"https:\/\/voomisupply.com\/products\/parker-520431000-4-way-2-position-valve-1-4-inch-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
