Raise & Lower Valves

Raise and Lower valves are used in air suspension systems to adjust the chassis height during loading operation. Versions with RtR (Reset to Ride Height) can reset the suspension to normal operation height by speed related signal from ABS or EBS systems (usually at 15 kph).

COLAS+ is the 2nd generation of the well known COLAS product range.
