Description

This multi-circuit protection valve is a critical component within the pneumatic brake system, ensuring precise pressure regulation across multiple circuits. Designed with high-strength components, it provides reliable protection for heavy commercial vehicle braking operations.

The 303.02.0002 is the OE equivalent of the MERCEDES BENZ 0034315506 and FAUN 99707005559 used in heavy-duty vehicles. This high-quality part is also compatible with WABCO 9347050020 systems. It is engineered to maintain optimal pressure stability during various driving conditions.

The technical configuration features multiple ports including Port 1 through Port 8 with specific threading like M22x1,5 and M12x1,5 to ensure a precise fit within the pneumatic circuit. Technicians should verify the opening and closing pressure settings—such as the 9 BAR requirement for Port 21/22—during installation to ensure system integrity.

Maintaining the correct pressure thresholds is vital for the safety of the vehicle's braking performance. Always consult with your authorized distributor for precise fitment verification and technical guidance.
