Manual insulation ball valves
Product features:
The product has good insulation and cold reserving properties, and the valve diameter is the same with the pipe diameter, the medium flow is linear, the resistance is small, it is suitable for the liquid medium of easy to freezing, high viscosity mostly. At the same time it can effectively reduce the heat loss of pipe in the media. The overall clamp design can insulate and reserve cold equably. clamp, the outside of body welded with the clamping pipes, allowing the maximum pressure of the steam or cold water to 1Mpa.
It is mainly used in petroleum, chemical, pharmaceutical, food and other systems, to transmit the high viscosity medium that will be solidified at room temperature.
