Description
The pneumatic stability of the braking system relies heavily on high-quality components that manage air distribution under pressure. This 4-circuit protection valve is engineered to ensure precise control and reliability within the brake system, maintaining optimal pressure across multiple circuits.
The VADEN ORIGINAL 303.02.0050 is the OE equivalent of the KNORR-BREMSE AE4644 and K019907N0 even when used in KNORR-BREMSE systems. This component features a primary Port 1 of M22x1,5 and four secondary ports (Ports 21 through 24) of M16x1,5 each. It operates at a nominal pressure of up to 20 BAR, with specific opening pressures set at 7 BAR and closing pressures at 5,5 BAR to ensure system safety.
For workshop technicians, this part offers a robust solution for heavy commercial vehicle maintenance. The precise thread specifications and pressure thresholds are designed to meet stringent industrial standards for air brake protection circuits. When replacing worn components, ensure all connections are secure to maintain the integrity of the pneumatic flow.
Regular inspection of the valve and its connection points is recommended to prevent pressure drops in the braking system. This product provides a dependable interface for managing high-pressure air distribution in professional workshop environments.
