301.01.0004 MERCEDES BENZ Unloader Valves

The technical precision of the braking system is essential for heavy commercial vehicle safety and operational efficiency. This unloader valve is engineered to manage pneumatic pressure-regulating functions with high reliability. Designed for demanding environments, it ensures consistent pressure control within the pneumatic circuit.

This component is the OE-equivalent of the MERCEDES BENZ 002 431 30 06 and WABCO 975 300 014 0 unloader valves used in heavy duty truck and bus braking systems. It maintains strict compatibility with MERCEDES BENZ systems to ensure seamless integration into existing pneumatic architectures.

For workshop technicians, this part offers straightforward assembly thanks to its standard M22x1,5 port dimensions on both Port 1 and Port 21. Regular maintenance and checking the cut-out pressure of 8,1 BAR / 0,2 BAR is recommended to ensure the integrity of the air brake system during service intervals.

Reliable performance is achieved through the use of heavy-duty grade materials that withstand constant pressure fluctuations. This ensures that the unloader valve performs its critical function in maintaining system stability across various driving conditions.
