Pneumatic valve is a device that uses gas pressure to control the valve switch, which has the following advantages:

1. Quick response: The opening and closing speed of the pneumatic valve is very fast, which can meet the requirements of fast control.

2. Simple structure: Pneumatic valves have a simple structure, no electrical components, are not easily affected by moisture, corrosion, etc., and have a long service life.

3. High reliability: Pneumatic valves have a simple working principle, high reliability and easy maintenance.

4. High safety: Since the pneumatic valve has no electrical components, the danger caused by electrical failure is avoided.

5. Energy saving and environmental protection: Pneumatic valves can use compressed air as the power source, which will not produce pollution and have the advantage of energy saving.

Combining the above advantages, pneumatic valves are widely used in chemical, petroleum, pharmaceutical, food, aerospace and other fields, and play a great role in realizing automatic control, improving production efficiency, and ensuring safety.
