303.02.0116 WABCO 4-circuit protection valve

This specialized pneumatic component functions as a critical safety element within the braking system of heavy commercial vehicles. It manages air pressure distribution across multiple circuits to ensure reliable braking performance under various operating conditions. Designed with high-strength components, it provides stable pressure regulation to maintain system integrity.

303.02.0116 is the OE-equivalent of the WABCO 934 714 404 0 4-circuit protection valve used in WABCO systems. This component is engineered to meet strict technical standards for pressure modulation and circuit isolation, ensuring it functions correctly within complex pneumatic architectures.

For workshop technicians and fleet managers, this part offers precise pressure control with specific opening and closing thresholds. The integration of M22x1,5 Voss ports ensures a secure and standardized connection for reliable assembly in heavy-duty braking environments. Regular inspection of the valve's pressure response is recommended to maintain optimal safety standards during routine maintenance.
