The insulation jacket flange butterfly valve is mainly connected with double flanges to prevent some special media from solidifying. The jacket can use steam or hot oil to isolate the internal medium. The main material is carbon steel or stainless steel. The operation method can be worm gear operation, electric or pneumatic actuator.
Insulated cast steel hard sealed high-temperature resistant butterfly valve
Most suitable for liquid media that are prone to solidification and high viscosity. At the same time, it can effectively reduce the heat loss of the medium in the pipeline. Integrated jacket design ensures even heating and cooling. The outer side of the jacket is welded with a jacket connecting pipe to the valve body, allowing a maximum pressure of 1MPa for steam or cold water. Mainly used for conveying high viscosity media that solidify at room temperature in petroleum, chemical, pharmaceutical, food and other systems.
