Description

The heavy duty 4-circuit protection valve is a critical component within the pneumatic brake system of heavy commercial vehicles, ensuring pressure stability across multiple circuits. This component is engineered with high-strength components to maintain precise regulation of air pressure during operation. The device features one M22x1,5 main port and four M16x1,5 auxiliary ports, specifically calibrated for reliable performance in demanding environments.

303.02.0100 is the OE-equivalent of the WABCO 934 714 119 0 4-circuit protection valve used in DAF, IVECO, MERCEDES BENZ, SCANIA, and STEYR vehicle systems. This part is also compatible with several other heavy-duty brands including IRISBUS and PACCAR to ensure optimal braking system integration and safety.

Workshop technicians should note the specific pressure settings during installation to ensure system integrity. The opening pressure for ports 21, 22, 23, and 24 is set at 6,5 BAR, while the closing pressure is maintained at 5,5 BAR. Regular inspection of the port threads and seals is recommended to prevent pneumatic leaks in the braking circuit.
