Product Description
Product Introduction 4202010LG018 Solenoid Valve is an electronically controlled pneumatic switch component for HFC JAC light truck engine aftertreatment system. It receives electrical signals from ECU to open or close the air passage, controlling air flow to actuate related valves in SCR system and maintain normal urea delivery logic. This aftermarket replacement solenoid valve fixes common faults including air channel blockage, delayed switching action, air leakage and dashboard fault codes caused by aging coil, stuck spool and cracked sealing components of original valves, ensuring stable SCR emission control and avoiding vehicle power limitation for urban logistics light commercial vehicles.
Product Advantages High-performance electromagnetic coil delivers stable response and strong anti-interference ability under engine vibration. Reinforced valve body material resists moisture and fine dust erosion. Precision spool structure ensures reliable air on/off switching and reduces air leakage risk. Each valve undergoes electrical and air tightness testing before shipment, compact OEM-style connector for direct plug-in installation and convenient system maintenance.
