BZ41H and BZ41Y jacketed insulation gate valve
Series of products are mainly used in petroleum, chemical, pharmaceutical, metallurgical, electrical and other systems, in order to transport at room temperature will be solidified high viscosity medium.
[product characteristics]
1, not only can prevent the viscous medium solidification in the pipeline, but also can reduce the heat loss in the cryogenic medium of the pipeline;
2, using welded steel jacket casting more pressure than strong, and fei;
3, because the diameter of the valve is consistent with the inner diameter of the pipeline, the medium is straight flow, the flow resistance is small, the most suitable for easy solidification, high viscous liquid medium.
