WCB insulation ball valve has the characteristic of heat and cold preservation. Valve is manufactured according to GB standard, connection flange according to 79-97 standard, Applied in petroleum, chemical, metallurgical, pharmaceutical industry.
Due to the use of steam jacket insulation, so even if the outside temperature dropped to below zero, the valve is still flexible operation to ensure that the pipeline can be disconnected, this advantage is what general valve doesn't have. It is the ideal control valve for heavy oil delivery pipes.
According to user needs, inject into the jacket with steam, heat transfer oil, cooling water, cold air and so on, so that the entire valve temperature will rise or drop to the required temperature, to prevent the crystallization of the media.
