Cast steel flange butterfly valve

summary:

Cast steel flange butterfly valve refers to a cut-off valve with a cast steel valve body, flange connection method, and butterfly plate rotating opening and closing structure. Its core feature is to achieve fluid on/off control by rotating the butterfly plate 90 ° around the valve stem axis, with a compact structure (only 1/3 of the length of the same diameter gate valve) and low flow resistance (resistance coefficient Cv value of 1200), suitable for large-diameter (DN50~DN2000), medium and low-pressure (PN1.0~PN16) water supply and drainage, gas, thermal and other pipeline systems.
