Description

What does a pressure limiting valve do?

This pressure limiting valve plays a critical role in regulating air pressure within the pneumatic brake system. By maintaining a stable outlet pressure of 4 BAR, it prevents system overpressure and ensures consistent braking force, which is essential for the safety of heavy commercial vehicles during operation.

Vehicle and engine compatibility

The component is engineered for high-strength durability and is compatible with Scania and Langendorf vehicles. It also serves as a reliable alternative for systems requiring precise pressure regulation across various heavy-duty applications.

Installation and maintenance

Installation requires careful attention to the M22x1.5 port connections to ensure a secure, airtight seal. Technicians should verify that the inlet pressure remains at 7.5 BAR and the adjustment range is set between 1.2 and 6.2 BAR according to the specific requirements of the vehicle's braking circuit.

Troubleshooting guidance

Regular inspection of the valve during routine maintenance can help prevent sudden pressure drops or leaks in the pneumatic lines. Consult your authorized distributor for fitment confirmation.
