Description
The precision engineered 4-circuit protection valve is a vital component within the pneumatic brake system, ensuring regulated air distribution across multiple circuits. This component maintains system stability by managing pressure differentials during various operating conditions, providing essential safety for heavy commercial vehicles.
The 303.02.0083 is the OE equivalent of the KNORR-BREMSE AE4190 4-circuit protection valve used in professional braking systems. It features a primary port of M22x1,5 and four secondary ports (21, 22, 23, and 24) measuring M16x1,5 each. Each circuit is calibrated with an opening pressure of 7 BAR and a closing pressure of 4,8 BAR to ensure consistent performance.
For workshop technicians and fleet managers, this part offers reliable integration into existing pneumatic architectures. The robust design is engineered to withstand high-pressure cycles without compromising structural integrity. Proper installation and regular inspection of the port seals are recommended to maintain optimal braking efficiency.
Maintaining the integrity of the brake system through high-strength components is crucial for heavy commercial vehicle safety. This part provides a dependable solution for maintaining pressure regulation across all four independent circuits.
