The flow characteristics of the electric ball valve are mainly shown in the resistance during flow, discharge capacity, flow quantity characteristics, sealing grade, etc. The special properties of the material during operation are mainly shown in the pressure, operating temperature, corrosion characteristics, whether it contains solid particles, whether the medium is toxic, whether it will cause combustion and explosion, and the viscosity of the medium.

The disk shaped butterfly plate of the hard seal electric ball valve rotates around the axis, and the rotating point of view is between 0 ° and 90 °. When it rotates to 90 °, the valve is fully open. Now, the butterfly plate of the hard seal ball valve is installed in the diameter direction of the pipeline. Hard seal ball valve body in cylindrical channel. Hard seal ball valve, hard seal butterfly valve, as a component used to realize on-off and flow control of pipeline system, has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower, etc.
