Electric carbon steel ball valve

　　Summary of cast steel electric ball valve products

　　Cast steel by the electric ball valve ball valve and fine small electric actuator (KFF) series, the series of electric actuators are divided into type switch and the external regulation, by a direct current or direct current control, realize the ball valve switch. Can realize intelligent control, the electric ball valve opened or closed fast line, can effective to control and management of pipe network, to realize the automatic pipeline. Widely used in petroleum, chemical industry, water treatment, paper making, heating, light industry and other industries.

　　Cast steel electric ball valve features

　　1, the fluid resistance is small, its resistance coefficient with section of equal length.

　　2, simple structure, small volume, light weight.

　　3, compact and reliable, the widespread use of plastic ball valve sealing surface of materials, good sealing, also has been widely used in the vacuum system.

　　4, easy to operate, open and close quickly, from open to close just rotate 90 °, is advantageous for the remote control.

　　5, convenient maintenance, simple structure, the electric ball valve sealing ring are generally activities, remove the replacement is more convenient.

　　6, in the full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through, does not cause the valve sealing surface erosion.

　　7, wide applicable scope, size from small to several millimeters, big to a few meters, from high vacuum to high pressure can be applied.

　　8, relative to manual and turbine rotating ball valves, electric ball valves can be large caliber configuration (manual and turbine rotating ball valve is generally under 12 caliber, electric ball valve can now be reached 48 ") diameter.)
