ON/OFF HIGHWAY | MARINE GENSET VALVES

DescriptionThe Urea Doser Valve injects controlled amounts of finely atomized diesel exhaust fluid (DEF) into the exhaust system upstream of the SCR catalyst. The urea is converted via thermal decomposition into ammonia. Inside the SCR catalytic converter, the ammonia then reduces the nitrogen oxides into environmentally safe water and nitrogen enabling customers to meet current and future emission regulations. LISK has a wide range of in-house testing capabilities including but not limited to Engine Dynamometer, International Standards Testing, Vibration Testing, Environmental Testing and Hydraulic/Pneumatic Testing.
