Working Principle
What is Air Valve? Working Principles & Types – An air-operated valve, also known as a pneumatic valve, is a sort of power-operated pipe valve that works in the same way as a solenoid by using air pressure. As the air pressure rises, the compressed air pushes against the piston or diaphragm walls, causing the valve to open. The application determines whether the valve opens or shuts.
These valves are used for a variety of purposes in pneumatic systems, however, they are most commonly utilized for one of two purposes. When a certain pressure is achieved, the first activates a section of the system. The second avoids harm by maintaining a consistent pressure or flow rate inside a system or releasing pressure when it rises too high.

Function
When the truck brakes, the air pressure enters the exhaust valve and closes the air in the exhaust pipe, which slows down the engine and the vehicle, thus playing a braking role
