Description
The braking efficiency of a heavy commercial vehicle relies on precise pneumatic control, and this 4-circuit protection valve provides the necessary stability for critical systems. Designed with high-strength components, it ensures reliable pressure distribution across multiple circuits to maintain safety during operation.
This product is the OE equivalent of the KNORR-BREMSE AE4188. The 303.02.0082 is specifically engineered for compatibility with KNORR-BREMSE systems, ensuring seamless integration into the existing pneumatic architecture. It features a primary port of M22x1,5 and four secondary ports (M16x1,5) to manage diverse pressure requirements across the vehicle's braking circuits.
For workshop technicians, this component offers precise opening pressures (7 BAR for ports 21/22 and 6,5 BAR for ports 23/24) and consistent closing pressures of 4,5 BAR. Regular inspection of the port seals and pressure thresholds is recommended during routine maintenance to ensure optimal system performance.
The robust design of this valve makes it an essential part for maintaining the integrity of heavy-duty braking systems in various transport environments.
