A Chassis Levelling Valve from ProVia provides suspension control for vehicles fitted with air springs. It precisely modulates compressed air in the suspension bellows as a ratio of the vehicle’s load. The Chassis Levelling Valve ensures a constant ride height, charging the air suspension during loading and venting when unloading. It has been designed as a cost-effective alternative to OE components with no compromise on safety. Available in a range of variants, it is designed for compatibility with a wide choice of OE systems.
