Application scenarios:

Low voltage electric butterfly valve D943X-6ZNDN1800Suitable for flow regulation. Due to the significant pressure loss of butterfly valves in pipelines, the robustness of the butterfly plate to withstand the pressure of the pipeline medium when closed should also be considered. In addition, it is necessary to consider the limitations of the working temperature that the elastic valve seat material can withstand at high temperatures. The structural length and overall height of butterfly valves are relatively small, with fast opening and closing speeds and good fluid control characteristics. The structural principle of butterfly valves is suitable for making large-diameter valves. When a butterfly valve is required for controlling flow, it is important to choose the correct size and type of butterfly valve so that it can work properly and effectively. Electric regulating butterfly valves are suitable for use in freshwater, sewage, seawater, saltwater, steam, natural gas, food, medicine, oil products, various acid-base and other pipelines that require sealing, zero gas leakage in gas testing, high service life requirements, and working temperatures between -10 ° C and 150 ° C. Soft sealed eccentric butterfly valves are suitable for bidirectional opening, closing, and adjustment of ventilation and dust removal pipelines, and are widely used in gas pipelines and waterways in metallurgy, light industry, power, and petrochemical systems. Metal to metal wire sealed double eccentric butterfly valve is suitable for urban heating, gas supply, water supply and other gas, oil, acid and alkali pipelines as a regulating and throttling device.
