Description

What does an ECAS solenoid valve do?

This ECAS solenoid valve is a critical component within the electronic air suspension control system, responsible for regulating air flow to the springs via ECU-triggered electrical commands. Built with high-strength components, it ensures reliable inflation, deflation, and holding functions even under demanding operating conditions.

Vehicle and engine compatibility

This component is specifically designed for use in DAF and Renault Trucks vehicles. It functions as a high-quality alternative within the air suspension electronics, maintaining precise pressure regulation throughout the system's operation.

Technical specifications and installation

The valve features multiple M22x1.5 VOSS ports (Ports 11, 21, 22, 23, 24, 25, and 26) to accommodate complex pneumatic routing. It is engineered to operate effectively at a pressure of 20 BAR, making it suitable for heavy commercial vehicle suspension requirements.

Maintenance and troubleshooting

To ensure optimal performance, technicians should inspect all M22x1.5 VOSS connections for integrity during installation. Regular checks of the electrical signal and pneumatic lines can prevent unexpected suspension level fluctuations. Consult your authorized distributor.
