Butterfly valves feature a simple structure, small size, light weight, low material consumption, small installation dimensions, rapid opening and closing, 90° reciprocating rotation, and low driving torque. They are used to cut off, connect, and regulate the medium in pipelines, and have excellent fluid control characteristics and sealing performance when closed.
Youdaoplaceholder0 Chemical industry : Butterfly valves are used to control the flow of various corrosive media and are suitable for high-temperature, high-pressure environments with strict sealing requirements .
Butterfly valves have a simple structure, mainly consisting of the valve body, valve stem, butterfly plate and sealing assembly. They have few parts and low material usage.
Regularly conduct a visual inspection of the butterfly valve, including the valve body, disc, stem and other components, to check for wear, corrosion or looseness. At the same time, check whether the connecting bolts between the valve and the pipeline are loose, as well as whether there are any signs of leakage in the valve's stuffing box, flange gasket and other parts. In addition, check whether the valve opening is consistent with the actual control signal by the opening indication of the electric actuator or by manual operation on site .
