Electric insulated ball valves are typically used in applications where heating/trace media flows through the jacket to prevent material crystallization and pipeline blockage, especially in locations with infrequent operation and poor material flowability. Depending on operating conditions, the jacket of an electric insulated ball valve can utilize condensate to prevent crystal precipitation caused by overheating, or employ hot water, steam, thermal oil, and other media for tracing. It offers excellent thermal insulation and cooling properties, making it ideal for conveying high-viscosity media that solidify at ambient temperatures.
