This dosing valve precisely injects diesel exhaust fluid (DEF) into the exhaust stream to help reduce nitrogen oxide (NOx) emissions and maintain emissions compliance.\u003c\/p\u003e\n\u003cp data-start=\"1801\" data-end=\"2239\"\u003eThe DEF dosing valve plays a critical role in the aftertreatment system by delivering controlled amounts of DEF to the SCR catalyst, where harmful NOx emissions are converted into harmless nitrogen and water vapor. A properly functioning dosing valve ensures accurate DEF delivery, optimal emissions reduction, and consistent engine performance while preventing fault codes or derate conditions related to emissions system inefficiencies.\u003c\/p\u003e\n\u003cp data-start=\"2241\" data-end=\"2633\"\u003eEngineered for the demanding thermal and vibration conditions found in heavy-duty trucking applications, this replacement DEF dosing valve provides reliable operation for fleet maintenance, emissions repairs, and preventive service programs. Always verify engine model compatibility and electrical connector configuration prior to installation to ensure proper fitment and system performance.\u003c\/p\u003e\n\u003ch2 data-start=\"2635\" data-end=\"2650\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-start=\"2651\" data-end=\"2954\"\u003eDirect replacement for OEM 22391563\u003cbr data-start=\"2686\" data-end=\"2689\"\u003eAlltrux Part Number: ATX24263\u003cbr data-start=\"2718\" data-end=\"2721\"\u003eDEF dosing valve for SCR aftertreatment systems\u003cbr data-start=\"2768\" data-end=\"2771\"\u003eProvides precise DEF injection for NOx emissions reduction\u003cbr data-start=\"2829\" data-end=\"2832\"\u003eSupports proper emissions compliance and engine performance\u003cbr data-start=\"2891\" data-end=\"2894\"\u003eDesigned for Volvo and Mack D11, D13, MP7, and MP8 engines\u003c\/p\u003e\n\u003ch3 data-start=\"2956\" data-end=\"2984\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp data-start=\"2985\" data-end=\"3258\"\u003eBrand: Alltrux\u003cbr data-start=\"2999\" data-end=\"3002\"\u003ePart Number: ATX24263\u003cbr data-start=\"3023\" data-end=\"3026\"\u003eOEM Cross Reference: 22391563\u003cbr data-start=\"3055\" data-end=\"3058\"\u003eProduct Type: DEF Dosing Valve (SCR Injector)\u003cbr data-start=\"3103\" data-end=\"3106\"\u003eSystem: Emissions \/ Aftertreatment (SCR\/DEF)\u003cbr data-start=\"3150\" data-end=\"3153\"\u003eCondition: New Aftermarket\u003cbr data-start=\"3179\" data-end=\"3182\"\u003eApplication: Volvo and Mack Heavy-Duty Diesel Engines (D11, D13, MP7, MP8)\u003c\/p\u003e\n\u003ch4 data-start=\"3260\" data-end=\"3281\"\u003eCross References\u003c\/h4\u003e\n\u003cp data-start=\"3282\" data-end=\"3315\"\u003eOEM: 22391563\u003cbr data-start=\"3295\" data-end=\"3298\"\u003eALLTRUX: ATX24263\u003c\/p\u003e","brand":"JX Peterbilt","offers":[{"title":"Default Title","offer_id":44150917005492,"sku":"ATX24263","price":430.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7425\/5540\/files\/ATX24263.jpg?v=1771774090","url":"https:\/\/parts.rodoc.com\/products\/atx24263-def-dosing-valve-volvo-mack","provider":"Rodoc Leasing Sales \u0026 Service ","version":"1.0","type":"link"}
