Differences between pneumatic and electric valves

1、 Electric valves use electric motors as power, while pneumatic valves use compressed air as power.

Advantages of pneumatic valves: good performance for gas media and small diameter liquids, low cost, and convenient maintenance. Disadvantage: Due to the fluctuation of air compressor pressure, it is easily affected by water content in the air compressor in winter in the north, causing the transmission part to freeze and not move.

2、 Generally, pneumatic power is faster than electric power, and electric power is used for both hand and electric purposes. The price for both manual and pneumatic use is relatively high.

Advantages of electric valves: They have good effects on liquid media and large diameter gases, and are not affected by climate. Not affected by the pressure of the air compressor. Disadvantages: High cost and poor performance in humid environments.

3、 There are not many brands of electric valves that can achieve explosion-proof performance due to slow action of electric valves; Pneumatic valves act quickly and are relatively more expensive for explosion-proof purposes compared to electric soles (key accessories for pneumatic valves, larger brand accessories will be more expensive than electric valves).

4、 Electric valves are used in places with large pipe diameters, as they are difficult to achieve pneumatically. However, the stability of electric valves is not as good as that of slow pneumatic switches. The actuator may experience tooth jamming for a long time. Pneumatic valves have fast switching speed and high accuracy, but require a stable air source.

Generally, pneumatic drive is used in flammable and explosive hazardous areas or areas where gas sources are readily available.

The two are only differences in driving methods, and the methods of driving valve operation generally include manual, electric, electromagnetic, pneumatic or hydraulic, electrical linkage, or electro-hydraulic linkage.

1. Pneumatic drive: simple structure, easy access to gas source, fast switching speed, speed governor can be installed, so that the switching speed can be adjusted as required, the gas compressibility is large, and it is flexible when closed.

2. Electric drive: It has strong applicability, is not affected by environmental temperature, has a wide range of output torque, is easy to control, can achieve ultra miniaturization, and is easy to install, maintain, and repair.
