High temperature butterfly valves with heat sinks are widely used in high-temperature pipelines in various fields such as petroleum, chemical, metallurgical, and hydropower. They can be connected with flanges or clamps, and come with corrugated insulation covers. They are more resistant to high temperatures than ordinary butterfly valves
multi-layer soft folding fixed on the valve plate. Compared with traditional butterfly valves, this butterfly valve has the advantages of high temperature resistance, easy operation, frictionless opening and closing, increased torque near the actuator to compensate for sealing, improved butterfly valve sealing performance, and extended service life.
