Moment is larger than normal valve action of electric valve, electric valve switching speed can be adjusted, simple structure, easy maintenance, good work valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow.
Action for buffer characteristics of the gas itself in the process, not easy to damage due to get stuck, but must have a gas source, and its control system is more complicated than the electric valve.
The valve is widely used in saving energy consumption, pneumatic valve, manual valve on the installation cost and efficiency are not as good as the electric valve.
The advantage of electric valve: high efficiency, saving energy consumption.
On liquid medium and large diameter gas effect is good, is not affected by climate.
Is not affected by air compressed air pressure.
Of course price cost of electric valve is not dominant, relative to lower the maintenance costs.
Due to the electric valve for easy assembly, low failure rate, and can meet the demand of industry automation, the advantages of industry is more cost-effective option.
Because of the use of general traditional pneumatic valves, not avoid such as piping, solenoid valves and compressors can match, and electric valve is a motor drive, simple and convenient installation, and installation of electric valve can cooperate factory original control circuitry, other costs can be saved.
In addition, the open and close more smooth in motor drive way, without too much momentum moment failure rate can be greatly reduced.
