With the large-scale application of butterfly valve products in the domestic market, hard-sealed butterfly valves and soft-sealed butterfly valves have been developed. The utilization rate of this kind of hard-sealed butterfly valve is relatively high, and it is also one of the more recognized butterfly valve products in the market. There are common metal hard-sealed butterfly valves, which are made of metal materials, and electric hard-sealed butterfly valves are butterfly valve products that can operate according to the electric drive mode, and there are two-way pressure hard-sealed butterfly valves, which are mainly butterfly valves that can achieve two-way pressure. Products and so on. However, there are many types of hard-seal butterfly valves, and they are also different in use, medium, and performance.
The electric hard-sealed butterfly valve is designed and manufactured with a new structure that is welded between a centerline disc plate and a short structure steel plate. It is compact in structure, light in weight, easy to install, small in flow resistance, large in flow, and easy to operate. There are no connecting rods, bolts, etc., reliable work, long service life and many other advantages. It can be installed in multiple positions and is not affected by the flow direction of the medium.
