ALL ALUMINUM ALLOY VALVE COMPONENTS 14 bar DIRECT OPERATED BUBBLE-TIGHT VALVES The robust internal solenoid valve architecture maximizes flow rates, provides bubble-tight sealing, and guarantees operation up to 16 bar for millions of cycles.op and close the main orifice. A: Product Overview The two-position four-way high-temperature solenoid valve group is the core execution component in the air suspension system. Its function is to inflate, exhaust or hold the air spring according to the command issued by the ECU electric control unit to complete the function of adjusting the height of the vehicle. In order to realize all the necessary functions, a large number of solenoid valves are often used in the automotive electronically controlled air suspension system. The connection between the circuit and the pneumatic circuit is complicated. The system uses the newly designed quadrupole solenoid valve group to merge all the valve bodies. Optimization, which simplifies the air circuit and circuit to the utmost, makes installation easier and reduces the failure rate of the entire system. Two: Scope of application The quadruple integrated solenoid valve is the core actuator in the air suspension system. Together with the other components of the control system, it forms a complete system, which can be applied to the modification of most ordinary, intermediate and medium-class cars on the market. Product features and interface sizes are consistent with foreign products of the same type and are interchangeable. Three: main function The quadruple integrated solenoid valve is the core actuator in the air suspension system. Its function is to inflate, exhaust or hold the air spring according to the command issued by the ECU's electronic control unit to complete the function of adjusting the height of the vehicle. The electronically controlled suspension four-integrated solenoid valve group adopts German imported connectors, which are more flexible and interchangeable with foreign products of the same type. The use of quick-release gas pipe joints ensures the quality of the product while improving the product's face value. Four: Installation requirements The solenoid valve group can be installed in the trunk. The airflow should be ensured in the vicinity of the exhaust port, and the exhaust clearance should be greater than 30mm at the exit.
