301.01.0013 Unloader Valves — DAF Compatible

The 301.01.0013 Unloader Valve serves a critical role in regulating pneumatic pressure within the brake system of heavy commercial vehicles. By managing air-flow-related pressure changes, this component ensures the stability and responsiveness of the pneumatic circuit during operation. Built with heavy-duty grade materials, it is designed to withstand rigorous industrial environments and maintain consistent performance under varying thermal and mechanical loads.

This component is an OE-equivalent for several high-standard systems, including DAF (1519343), IRISBUS (99432140), IVECO (04826204, 4775736, 4775738), PACCAR (CD9753031200), and WABCO (975 303 120 0). 301.01.0013 is the OE-equivalent Unloader Valve used in DAF, IRISBUS, IVECO, and PACCAR heavy commercial vehicle systems. Its precise engineering guarantees seamless integration with existing braking hardware to prevent pressure drops or system failures.

For workshop technicians and fleet managers, the installation process requires strict adherence to port specifications to ensure a leak-free seal. The unit features an M22x1,5 thread on Port 1 and Port 21, and an M12x1,5 thread on Port 23. Regular inspections of the recycle valve functionality and port integrity are recommended during standard brake system maintenance intervals to ensure optimal vehicle safety and longevity.
