Air Operated Valves, also known as a pneumatic valve, are a type of powered pipe valve that uses air pressure to perform a similar function to a solenoid. As the air pressure increases, the compressed air begins to push against the piston or diaphragm walls causing the valve to act. The opening and closing of the valve depends on the application. These valves are used for many functions in pneumatic systems, but mostly serve one of two functions. First, it activates a part of the system when a certain pressure is reached. Second, it prevents damage by maintaining a constant pressure or flow rate within the system or by releasing the pressure when it reaches extreme levels.
How do Air Operated Valves (Pneumatic valve) work?
Air Operated Valves operate by using compressed air to actuate a piston or diaphragm, which opens or closes the valve. When compressed air is supplied to the actuator, it creates a pressure that moves the piston or diaphragm and causes the valve to open and close. The amount of pressure applied determines how much the valve opens and closes. Air operated valves are commonly used in industrial applications where electricity is not readily available or safe to use.
