COLAS® Suspension Control Valve

The COLAS® Valve provides manual raise and lower of the deck height of the commercial truck or trailer. The COLAS® Valve takes the place of many components, fittings and plumbing, and can be used for single and dual suspension valve systems. One valve replaces multiple pilot valves, solenoid and manual valves, and the customary hand valve, eliminating many potential leak points, while providing a simpler installation.

 The COLAS® Valve can be used in manual mode or with pneumatic reset to ride. The pneumatic reset to ride is accomplished when the supply line pressure to release the spring brakes of the vehicle is charged. When the reset to ride feature is used, the handle will pop out and the vehicle will automatically return to the height dictated by the suspension height control valve. This eliminates operator error to reset the valve when the vehicle is moving.
