Compared with traditional butterfly valves, power-driven electric butterfly valves can not only be remotely controlled, but also have stable sealing performance. The key lies in the special double eccentric structure, which maintains the stability of the electric butterfly valve, and the sealing is beyond the scope of the traditional butterfly valve. In addition, the shaft diameter of the valve stem of the electric butterfly valve is sealed with a graphite compression sealing ring to prevent the butterfly valve from leaking. In addition, because the electric butterfly valve is driven by electric energy, the work efficiency is greatly improved compared with manual drive. Therefore, the good performance of the electric valve improves the production efficiency of the enterprise.
