Description

What does an ECAS solenoid valve do?

This ECAS solenoid valve serves as a critical component within the electronic air suspension control system, managing pneumatic distribution to maintain optimal vehicle leveling. Built with high-strength components, it ensures precise air flow regulation under heavy-duty operating conditions.

Compatible vehicles and systems

This component is designed for MAN trucks and is compatible with WABCO systems. It functions effectively within the electronic chassis actuator system to provide stable suspension geometry during transport.

Installation and maintenance

Installation requires careful attention to the M22x1.5 VOSS port connections (Ports 11, 21, 22, and 23). Technicians should verify that all connections are secure and that the system pressure remains within the rated 20 BAR limit to prevent leaks or pneumatic failure.

Troubleshooting guidance

Regular inspection of the solenoid valve helps prevent air suspension irregularities. If uneven leveling or slow response occurs, checking the solenoid valve and its pneumatic lines is recommended.

OE cross-reference

303.04.0027 (ECAS Solenoid Valve) is the equivalent of the MAN and WABCO OE numbers. This part directly replaces MAN OE numbers 81259026144, 81259026237, 82259026237. It also replaces WABCO OE number 4728800240.
