Haldex Commercial Vehicle Systems announces the addition of the ILAS E Air Suspension Valve. The Haldex ILAS E Air Suspension System Valve can control the position of the lift axles through an electrical connection. A 12V power supply is needed to keep the lift axles in the raised position. When power is removed the lift axles will automatically be lowered. This can be simply controlled via an electrical switch. When coupled with the Haldex TRS System, the lift axles can be controlled to raise and lower automatically as the air suspension reacts to changing loads in the trailer.
