Description

This high-strength component is essential for maintaining precise pneumatic control within the braking system of heavy commercial vehicles. As a critical part of the pneumatic circuit, it ensures rapid response and reliable pressure regulation during operation. The component is engineered to withstand demanding service environments while maintaining consistent functionality.

303.01.0032 is the OE-equivalent of the WABCO 973 001 031 0 relay valve used in DAF, IVECO, IRISBUS, and RENAULT TRUCKS systems. It also serves as a direct replacement for the IVECO 980895 and RENAULT TRUCKS 5430018273 specifications, ensuring seamless integration with existing brake-suspension hardware.

Workshop technicians should verify all port connections—Port 1 (M22x1,5), Port 2 (M22x1,5), and Port 4 (M22x1,5)—to ensure a leak-free installation. This part is designed for a maximum operating pressure of 8 BAR. Regular inspection of the pneumatic lines and ensuring clean air supply is recommended to maintain the longevity of the valve and the overall braking system performance.
