Technical data

ILAS‑EP is an electro‑pneumatic lift axle valve designed for integration into air suspension systems. The valve controls the air supply between the reservoir, suspension system and lift axle bellows to manage axle position. It operates via an electrical signal input and is compatible with both manual control and automated control via EBS systems.

The design features a lightweight plastic housing, enabling significant weight reduction while improving resistance to corrosion and environmental conditions. The valve is optimised for controlled air flow, ensuring a balance between operational efficiency and safety during lifting and lowering operations
