The core component for the air suspension
Air suspensions are irreplaceable for the floating, elegant and soft driving experience in luxury limousines. They ensure comfort, driving stability and the safety of passengers. Alongside the compressor unit, the pneumatic valve unit is the elementary component of the air supply system that controls the vehicle’s air springs. RAPA supplies specially developed solenoid valve blocks with switching valves (2/2-way valves) for this purpose. They are used to regulate the air volume in the air suspension bellows.
Customers are leading global Tier 1 system suppliers and OEMs. Combining several solenoid valves into one valve block not only guarantees a compact design and less weight, but also less effort when connecting the air lines. The air suspension control unit acts as the switching point: it controls the valve block accordingly and activates the compressor.
