Description
What does a pressure limiting valve do?
This pressure limiting valve plays a critical role in maintaining stable pneumatic pressure within the heavy commercial vehicle brake system. By regulating the air flow, it prevents overpressure and ensures the braking components operate within their safe functional limits under heavy loads.Vehicle and system compatibility
The component is engineered to be compatible with MAN vehicles and WABCO systems. It operates with an inlet pressure of 12.5 BAR and provides an outlet pressure of 9.3 BAR, making it a reliable choice for demanding fleet operations.Installation and maintenance
Installation requires attention to the M22x1.5 VOSS port connections to ensure a leak-free seal. Technicians should verify the adjustment range of 5.8 to 10.8 BAR during assembly to match the specific requirements of the vehicle's pneumatic circuit.System reliability and selection
Regular inspection of the valve helps prevent sudden pressure drops or system instability. Consult your authorized distributor to ensure correct fitment for your specific heavy commercial vehicle application.OE cross-reference
