What is the purpose of the leveling valve？

The leveling valve is a component of a vehicle's air suspension system that is responsible for maintaining the proper ride height of the vehicle. The purpose of the leveling valve is to ensure that the vehicle is level and balanced, regardless of the weight of the load being carried or the terrain being driven on.

The leveling valve works by measuring the pressure of the air suspension system and adjusting it to maintain a consistent ride height. If the vehicle is carrying a heavy load, the leveling valve will increase the pressure in the air suspension system to keep the vehicle level. Conversely, if the vehicle is carrying a light load, the leveling valve will decrease the pressure to prevent the vehicle from riding too high.

The leveling valve is particularly important for commercial vehicles that carry heavy loads, such as trucks, buses, and trailers. Properly functioning leveling valves ensure that these vehicles can safely and efficiently transport their cargo while maintaining stability and control on the road.
