Butterfly valves have always been the focus of attention in the field of valve industry. Following the increase in technical content, many series of products and diversified products have been continuously launched. The structural principle of the hard-sealed butterfly valve is especially suitable for making large-diameter valves. Hard seal butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, water treatment, etc., but also used in cooling water systems of thermal power stations.
The electric hard-sealed flange butterfly valve is a combination of an electric actuator and a metal hard-sealed flange butterfly valve. The electric flange hard-sealed butterfly valve is driven by an electric actuator. The rotating valve stem drives the disc to switch at 90°. Use for opening and closing or flow adjustment. There are many types of hard seal butterfly valves. Common hard seal butterfly valves are mainly divided into single eccentric hard seal butterfly valves, double eccentric hard seal butterfly valves, triple eccentric hard seal butterfly valves, multi-layer hard seal butterfly valves, two-way hard seal butterfly valves, etc. The selection is generally It is selected according to the temperature, pressure, medium and sealing performance of the working condition.
