Ball valve is most suitable for switch, cut off valve use, V-type ball valve. In addition to the pipe parameters, special attention should be paid to the environmental conditions of the use of the electric valve. Because the electric device in the electric valve is a mechanical and electrical equipment, its use state is greatly affected by its use environment. In general, electric ball valve, butterfly valve in the following environment to use special attention.
