The size of the electric ball valve itself is relatively small. Because the material selection is all metal, the weight of the electric ball valve is higher than that of the general electric valve, and the components are more complex, so the objects that can be processed are more abundant. Operation also needs people with higher technical experience to control. The probability of failure is very small. It is better to control the flow inside the equipment to reduce the wear between parts.

2) On the disc plate of the electric butterfly valve, the matching flange must be installed to avoid adverse effects during use. If it is installed in the pipeline, the best installation position should be vertical installation. Since it is installed vertically, it is not allowed to install it upside down to avoid adverse effects on the butterfly valve during use. At the same time, when in use, it is also required to adjust the flow, which is generally controlled by the turbine box.
