The difference between characteristics of pneumatic valves and electric valve

With the continuous improvement of technology, pneumatic valves and electric valve has been replaced in many conditions the use of manual valves. Many users don't know how to choose to use pneumatic valve and the electric valve. To correctly choose pneumatic valves and electric valves must first understand the use of pneumatic and electric valves.

Pneumatic valves and electric valve is made up of electric actuators, and pneumatic actuators with various types of valves, used in the working condition of instead of manual valves to achieve automatic control. The biggest difference between the two kinds of valve is the driving source is different, how to choose the two valves in be used actually basically see actual working condition is suitable for what kind of valve. Here is the general use difference between these two kinds of valves.

First of all, pneumatic valve action time faster than electric valve. And pneumatic valve can open again and again in a short time, switching frequency is too high will lead to motor of electric valve fever. So the occasion of pneumatic valve is more applicable to the need to quickly cut off. Because the electric valve actuators are electronic components, in the event of a failure is easy to produce sparks. So than electric pneumatic valve valve is more suitable for use in flammable and explosive occasions. In the maintenance of pneumatic valve maintenance convenient and requirements for the professional and technical maintenance staff is not high. Electric valve, on the other hand. But the maintenance cost of electric valve pneumatic valve is much higher. In field conditions, the use of pneumatic valves on site for a gas source, and electric valve can be used to power supply is connected. It is much convenient than pneumatic valves.
