Pneumatic valve types

As an important component of industrial pipelines, pneumatic valves are divided into two categories: air-open valves and air-close valves according to different working properties and application requirements. Air-open valves are mainly used to adjust the flow and pressure of material transportation, but in actual applications, flash evaporation and cavitation may occur, resulting in increased valve vibration and noise, thus affecting the service life.

Therefore, special attention should be paid to the possibility of these problems when selecting and using them.

Relatively speaking, air-close valves are mainly used for the transportation of gas in sealing devices, especially for situations where materials need to be discharged urgently, and can effectively avoid problems such as channel blockage and pressure rise.

Detailed explanation of pneumatic valve types
1. Ball valve: Ball valves are widely used in industrial and civil fields due to their simple structure, high pressure resistance, and fast opening and closing. It can open and close quickly, is not easily affected by medium corrosion, and is suitable for occasions that require frequent operation.

2. Butterfly valve: Butterfly valves have a simple structure, small size, fast opening and closing, and low flow resistance. They are suitable for large-diameter pipelines and scenes that require fast switching, but have poor sealing and are not suitable for high temperature and high pressure environments.

3. Gate valve: Gate valve is widely used in ordinary industrial pipelines due to its low flow resistance, labor-saving operation, no flow disturbance and no pressure drop. It is a cost-effective choice.

4. Globe valve: Globe valve has a reliable cut-off function and is suitable for occasions that require frequent switching. However, due to the large liquid resistance, it is not suitable for long-term use on large-diameter pipelines.
