Actuated by a palm button with spring return, it shifts between two positions to direct compressed air flow through the circuit. The valve carries a Cv rating of 0.298 and supports a maximum working pressure of 127.98 psi, with a rated flow of 7 SCFM. The 1\/8 inch thread port size suits compact pneumatic assemblies. Installation and service are typically handled by industrial maintenance technicians, automation specialists, or experienced mechanical contractors.\u003c\/p\u003e\n\u003cp\u003eThis valve fits applications where manual operator control of a pneumatic actuator, cylinder, or air-operated device is required. The palm button actuator is common on machine guarding stations, press controls, and assembly line pneumatic circuits where the operator must apply deliberate hand force to shift the valve. The spring return ensures the valve automatically resets to its default position when the operator releases the button, which is standard practice in safety-conscious pneumatic designs. It is suited for light-duty compressed air systems operating within its rated pressure range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-way, 2-position valve configuration for directional pneumatic control\u003c\/li\u003e\n  \u003cli\u003ePalm button actuator with spring return for manual, deliberate operation\u003c\/li\u003e\n  \u003cli\u003eCv rating of 0.298 with 7 SCFM flow rate\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 127.98 psi\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch thread port size for compact pneumatic assemblies\u003c\/li\u003e\n  \u003cli\u003eCompact body: 1.77 inches tall, 1.26 inches wide, 0.63 inches in length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-replacement or new-installation 3-way 2-position palm button air valve for compact pneumatic circuits requiring 1\/8 inch ported connections and operating pressures at or below 127.98 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and lock out the pneumatic supply line before removing or installing any directional control valve. Apply thread sealant appropriate for compressed air service to the port threads, taking care not to allow sealant into the valve body. Verify the system operating pressure does not exceed the 127.98 psi maximum rating prior to commissioning. Consult applicable OSHA machine guarding and NFPA pneumatic safety standards when integrating palm button actuators into operator control stations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: 3-Way, 2-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Palm Button with Spring Return\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCv Rating\u003c\/strong\u003e: 0.298\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 7 SCFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 127.98 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.45 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5330221512PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51739739455794,"sku":"5330221512PRO","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ded5a6a5920594a624b67f2486c0c8f.jpg?v=1788818383","url":"https:\/\/voomisupply.com\/products\/pro-source-5330221512pro-3-way-air-valve-palm-button","provider":"Voomi Supply","version":"1.0","type":"link"}
