Description
What does an unloader valve do?
This unloader valve plays a critical role in the air brake system by managing pressure levels within the compressor system. It ensures that the system operates within safe parameters by releasing air at a specific threshold, preventing over-pressurization during operation. Built with heavy-duty grade materials, it provides reliable performance under demanding conditions.Compatible vehicles and systems
This component is compatible with various heavy commercial vehicles including Mercedes-Benz, MAN, Scania, DAF, Iveco, Kenworth, Peterbilt, Case, Faun, Irisbus, Leyland and Neoplan. It is also suitable for use within WABCO systems.Installation and maintenance
When installing this unit, ensure all connections are secure. The component features specific port sizes: Port 1 is M22x1.5, Port 21 is M22x1.5, and Port 22 is M12x1.5. Regular inspection of the ports and the recycle valve functionality is recommended to maintain optimal pneumatic performance.Troubleshooting guidance
To ensure correct fitment, verify that the cut-out pressure of 7.3 BAR / 0.2 BAR matches your specific vehicle requirements. If you experience inconsistent pressure regulation in the air system, this valve may require inspection or replacement.OE cross-reference
