303.04.0030 ECAS Solenoid Valve for Volvo and Renault

What does an ECAS solenoid valve do?

This solenoid valve serves as a critical component within the electronically controlled air suspension system. It regulates the air flow to and from the air springs based on ECU commands to maintain optimal vehicle height and stability. Built with high-strength components, it is designed to withstand the rigorous vibrations and pressure fluctuations typical of heavy commercial vehicle operations.

Vehicle and engine compatibility

This component is engineered for compatibility with various heavy-duty models, including Volvo FH13, FM12, and FMX series, as well as Renault Trucks Magnum and Premium. It is also suitable for Mack Granite and Pinnacle trucks using MP7 or MP8 engines. Additionally, it is fitted to Scania trucks through specialized system compatibility.

Installation and maintenance guidance

For proper installation, ensure the M22x1.5 VOSS ports are clean and correctly seated to prevent leaks. The electrical connection utilizes a 24V Bayonet DIN 72585 A1-3.2-Sn/K2 interface to ensure secure communication with the electronic control unit. Regular inspection of the silencer and electrical terminals is recommended during routine suspension maintenance.

System performance and stability

Maintaining proper air pressure regulation through this valve is essential for preventing uneven chassis leveling or suspension instability.
