This high-performance unloader valve is engineered to ensure precise pneumatic control within the brake system of heavy commercial vehicles. Designed with robust components and optimized for durability, it maintains consistent pressure regulation even under demanding operating conditions.

The VADEN ORIGINAL 301.01.0017 is an OE equivalent of the WABCO 9753034630 used in various heavy-duty applications. It is fully compatible with several major systems including VOLVO F12, F7, FL12, and B12 series, as well as SCANIA, IVECO, and RENAULT TRUCKS. This specific part is also a direct replacement for MACK 63009753034630 and MERITOR S9753034630.

Technicians should note the technical specifications: Port 1 and Port 21 utilize M22x1,5 threads, while Port 22 is M12x1,5. The device features an integrated inflation valve and recycle valve functionality to ensure system stability. Always verify the cut-out pressure of 8,5 BAR to ensure compatibility with your specific vehicle setup.

Regular inspection of the pneumatic connections and port integrity is recommended during routine maintenance to prevent pressure loss in the braking circuit.
