What is typically the maximum pressure regulated by the safety valve in an air brake system?

The maximum pressure regulated by the safety valve in an air brake system is typically set at 150 psi. This is the threshold designed to ensure safety by preventing excessive pressure build-up within the air brake system.

Air brake systems rely on compressed air to operate effectively, and maintaining the correct pressure is crucial for optimal performance and safety. If the pressure exceeds this threshold, the safety valve is engineered to release excess air, thus preventing potential damage to the air brake components and ensuring that the brakes function correctly under varying conditions.

This pressure setting also aligns with industry standards and ensures that vehicles equipped with air brakes maintain a balance between sufficient pressure for effective braking and safety against over-pressurization.
