Jacketed Ball Valve

ALIS Valves offers Jacketed Ball Valves designed for reliable flow isolation and temperature management in industrial processes handling fluids that may solidify, crystallize or become highly viscous when cooled. These valves feature a conventional ball valve mechanism enclosed within an additional external jacket through which a heating or cooling medium can circulate, depending on the application. The jacket helps maintain the required process temperature around the valve body, supporting smoother flow and reducing the risk of material buildup or blockage. Heating media may include steam, hot water or thermal fluid, subject to the valve design and temperature ratings. Depending on the application, these valves are available with suitable body materials, ball and seat configurations, jacket connections, pressure ratings and flanged or other specified end connections.

Jacketed Ball Valves are commonly used in chemical processing, petrochemical plants, pharmaceutical manufacturing, resin production, polymer processing, bitumen handling and other applications involving temperature-sensitive or viscous materials. They can be specified for compatible process media within the valve’s rated pressure and temperature limits, with jacket design and heating requirements determined by the process conditions. Important selection factors include valve size, process media, operating temperature, pressure rating, jacket connection size, heating medium, seat material and thermal requirements. Buyers should also consider heat transfer efficiency, warm-up time, insulation requirements and the possibility of thermal expansion during operation. The jacket and valve body must be designed for their respective pressure and temperature conditions, and the heating medium must remain compatible with the complete assembly. Selecting the appropriate jacketed ball valve helps maintain process temperature, support consistent material flow and reduce the risk of solidification within compatible industrial systems.
