Description

The high-strength component serves a critical role within the pneumatic brake system, specifically managing air pressure regulation through the unloader valve mechanism. This part is engineered to maintain consistent pressure cycles and ensures the reliable operation of the air system in heavy commercial vehicles.

301.01.0036 is the OE-equivalent of the WABCO 975 300 100 0 unloader valve used in WABCO systems. This component is designed to meet strict technical specifications, ensuring seamless integration and long-term reliability within the vehicle's pneumatic architecture.

Workshop technicians should verify the port configurations, specifically Port 1 (M22x1,5) and Port 21 (M22x1,5), during installation to ensure a proper seal and prevent pressure leaks. Regular maintenance of the unloader valve and checking the cut-out pressure of 7,3 BAR / 0,2 BAR is essential for optimal brake system performance and safety.
