The operation of an air suspension valve

The valve is built directly into the pneumatic system that regulates the position of the floor level. Adjustment is carried out according to the requirements, as well as the peculiarities of the road conditions. The tap position forces the system to bleed or pump air. Currently, it is common to produce valves with a fixed position. In such cases, the level is any. Together with the valve, it performs work and lever control. Therefore, air poisoning often occurs.
