Description

What does an unloader valve do?

This unloader valve serves as a critical component within the air brake system, managing pressure regulation to ensure consistent air supply. Built with heavy-duty grade materials, it maintains stable performance under high-pressure conditions to support the safety and reliability of the braking system.

Vehicle compatibility and fitment

Designed for use in heavy commercial vehicles, this unit is compatible with Mercedes-Benz applications. It features specific port configurations, including M22x1.5 and M12x1.5 connections, ensuring a precise fit for the intended pneumatic circuit.

Installation and maintenance guidance

For professional workshop technicians, installation requires careful attention to port alignment and thread integrity. Proper seating of the M22x1.5 and M12x1.5 ports is essential to prevent air leaks and ensure the cut-out pressure of 8,1 BAR / 0,2 BAR operates correctly within the circuit.

Selection and troubleshooting

Consult your authorized distributor to confirm exact fitment for your specific vehicle model and engine configuration.
