Level Control Solenoid Valve: Description and Operation

Description

Four air spring solenoid valves ('-' control) and one ambient solenoid valve are embedded inside this solenoid valve block as shown in the circuit diagram below. When connecting the air tube to the solenoid valve block, carefully check the color dot which is marked on the valve and tube so that all colors should be matched each other.
The pressure sensor is built in the solenoid valve block so that it detects the internal pressure when lifting or lowering the vehicle height. Also it senses the pressure of reservoir tank every 30 minutes when the vehicle is running.
