SSP 275 Phaeton Air - Volkspage

Solenoid valvesAll in all, the air suspension has six solenoidvalves.The drain valve N111 together with the pneumaticdrain valve form a functional unit which isintegrated in the drier housing. The drain valveN111 is a 3/2 way valve and is de-energisedwhen closed.The pneumatic drain valve has two tasks: to limitpressure and to maintain residual pressure.Together with the self-levelling suspensionpressure accumulator valve N311, thefour air spring valves N148, N149, N150 andN151 are combined in the solenoid valve block.The valves in the solenoid valve block aredesigned as 2/2 way valves and are deenergisedwhen closed.The pressure on the air spring side/accumulatorside acts in the closing direction.To avoid confusion when connecting the pressurelines, the pressure lines are colour coded.The matching connections on the solenoid valveblock are also colour coded.Compressorconnectionfront left/redPressure accumulator/lilacElectricalconnectionfront right/greenrear left/blackrear right/blueSolenoid valve block withN148, N149, N150, N151and N311275_06651
