Description
This pressure limiting valve plays a critical role in maintaining stable pneumatic pressure within heavy commercial vehicle brake systems. By regulating the transition between pressure levels, it ensures that the braking system operates within safe, predefined limits during various loading conditions.
The component is engineered to be compatible with Knorr-Bremse systems, providing reliable performance in demanding environments. It features specific port dimensions of M22x1.5 and is designed to handle significant pressure fluctuations effectively.
Technicians should verify the transition pressure, which ranges from 7.5 BAR to 0.5 BAR, and the safety pressure of 9.0 BAR ± 0.5 BAR during installation. Regular inspection of the M22x1.5 ports is recommended to ensure a secure seal and prevent pressure drops in the braking circuit.
Proper selection of this valve ensures optimal system response and safety for the entire vehicle brake assembly.
