The biggest difference is that one uses electricity while the other uses gas! I. Electric valves use motors as power, while pneumatic valves use compressed air as power. (1) Advantages of electric valves: They perform well with liquid media and gases at large diameters, and are not affected by climate conditions. Not affected by the pressure of compressed air. Disadvantages: High cost, performs poorly in humid environments. (2) Advantages of pneumatic valves: effective for gas media and liquids with small diameters, low cost, and easy maintenance. Disadvantages: Affected by fluctuations in air compressor pressure, it is susceptible to moisture in the air compressor during winter in the north, which can cause the transmission components to freeze and stop functioning. II. Generally, pneumatic ones are faster than electric ones; electric ones are designed to be used as both flashlights and tools. On the other hand, those that are both pneumatic and manual come at a higher price. III. Electric valves are used in applications involving large pipe diameters, as it is difficult to use pneumatic valves in such cases. However, electric valves lack the stability of pneumatic valves, have a slower switching speed, and their actuators may experience gear jamming over time. Pneumatic valves feature fast switching speeds and high precision, but they require a stable air supply.
