Pneumatic insulation ball valve
The Pneumatic Insulation Ball Valve is a specially designed automated valve that integrates a high-performance ball valve structure with an external insulation jacket system and pneumatic actuator. It is developed for applications requiring temperature preservation, heat loss prevention, and reliable automatic flow control.
The valve features an insulated valve body design that maintains the temperature of the medium inside the pipeline, preventing solidification, crystallization, condensation, or viscosity increase during transportation. It is widely used for controlling high-viscosity fluids, thermal oil, asphalt, chemical liquids, molten materials, and other temperature-sensitive media.
Equipped with a pneumatic actuator, the valve provides fast response, remote operation, and stable automation performance. The optimized sealing structure ensures excellent shut-off capability, low operating torque, and long service life under demanding industrial conditions.
