At what maximum air pressure is the governor set to cut out?

The governor in an air brake system is a crucial component that regulates the air pressure in the system to ensure optimal performance and safety. The correct maximum cut-out pressure for the governor is typically set at 135 psi. This is the pressure at which the governor stops the compressor from pumping air into the system, preventing over-pressurization that could potentially damage the system or cause a brake failure.

Setting the governor to cut out at 135 psi ensures that the air brake system operates efficiently while maintaining sufficient pressure without exceeding safety limits. This standard is widely adopted in many air brake systems, aligning with industry regulations and the technical specifications required for proper operation. Understanding the correct cut-out pressure is essential for anyone involved in operating or maintaining air brake systems to ensure they function safely and effectively.
