Electric butterfly valve disc to install the pipe diameter direction. In the cylindrical channel of the electric valve body, disc-shaped disc around the axis of rotation, the rotation angle between 0 ° ~ 90 ° rotation to 90 ° when the valve is open all license conditions.

Electric butterfly valve has a simple structure, small size, light weight, only a few parts. And just rotate 90 ° to quickly open and close, easy to operate, the valve has a fluid control features. Electric butterfly valve is fully open position, the thickness of the disc is the only resistance in the medium flows through the valve when the valve pressure drop is small, it has a better flow control characteristics. Electric butterfly valve shells seal and metal seal two seal type. The elastic sealing valves, seals can be mounted on the body or attached to the disc periphery.

Metal sealed valves in general than the elastic sealing valves are long life, but it is difficult to completely seal. Metal seal can adapt to the higher operating temperature, flexible seal is the temperature limit of the defect.

If you require electric butterfly valve as a flow control to use is the correct choice of valve size and type. The principle of the structure of the electric butterfly valve is particularly suitable for the production of large diameter valves. Electric butterfly valves are widely used not only in oil, gas, chemical, water treatment and general industrial, but also for the thermal power plant cooling water system.

Electric butterfly valve clip-on electric butterfly valves and flanges two electric butterfly valve. Stud valve connection between two pipe flanges, flange type electric butterfly valve is a valve with a flange bolt valve on both ends of the flange connected to the clip-on electric butterfly valve on the pipe flange.
