303.04.0130.04 Repair Kit for ECAS Solenoid Valves

What is an ECAS solenoid valve repair kit?

An ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system. These kits allow the valve block to be repaired without replacing it entirely, providing a cost-effective maintenance solution for workshop technicians.

Vehicle compatibility and application

This kit is compatible with Knorr-Bremse systems and is used in various heavy commercial vehicle applications, including Volvo models such as the FM, FH, and VNL series, as well as Mack Granite and Renault Trucks Premium. It ensures the pneumatic system maintains constant chassis height by managing air bellows inflation and venting.

Installation and maintenance guidance

During installation, technicians should carefully inspect the valve block for any debris before renewing the internal components. Proper replacement of sealing elements helps prevent common issues like air leaks or delayed level response. Always ensure that the mounting surfaces are clean to maintain optimal performance of the electronic control unit commands.

Troubleshooting and performance

Regular inspection of these components can prevent vehicle sagging while parked and ensure the stability of the suspension system during operation.
