Air suspension
If technology is important, there is only
one air valve brand to consider
Innovation means imaginative and more efficient use of resources, identified increasingly as the key to a successful business strategy. These cutting-edge developments have more impact on air suspension where vital questions about optimum performance are finding radical answers. Its basic merits are well known, including enhanced safety and ride quality, reduced wear and tear and prolonged working life of tractors and trailers from poor road surfaces.
However, the value of air suspension systems goes far beyond this. It increases exponentially from their flexible capability to incorporate and integrate a range of key operational and wider management functions to optimise overall fleet running performance. Thus operators’ data process, analysis and communication requirements covering a wide range of areas – monitoring, tracking, diagnostics, servicing – may be met fully with tailored intelligent system solutions. Haldex has pioneered, promoted and inspired awareness of the valuable benefits available from an integrated systems approach. Its innovative product range offers an impressive choice of routes to cost-effective performance, e.g. COLAS® automatic ride height facility and ILAS® lift axle management system.

Key benefits
- Available with different flow rates for different type of installations
- Low weight.
- Suitable for both dual and single circuits
- Offers fast and easy installation
- Solutions available for all mechanical controlled air suspension systems

What sets us apart
Air Suspension Control Valves are used to automatically control the vehicle’s ride height by inflating and deflating the air suspension bellows to adjust for variations between loaded and unloaded vehicles. They are also used for cab suspensions to provide ride comfort for the operator and for bus suspension applications, including kneeling capability.
Our complete line of Air Suspension Control Valves reduces your downtime and lowers your cost of ownership.

COLAS®
The COLAS® Valve can be used to manually raise and lower the deck height of commercial vehicles and trailers.

ILAS®
The ILAS® valve controls the lifting of one or more axles by sensing a load through the primary air suspension.

EGP Levelling Valve
The EGP (Engineering Grade Plastic) levelling valve is a level control valve for single or dual channel air suspension systems
