Product details

The insulation jacket of BJ45W DC type heat preservation stop valve is welded between the two flanges of the valve, and the two connection ports of the insulation jacket are arranged on the side and bottom of the valve. The DC type heat preservation stop valve is suitable for pipelines in the chemical and fertilizer industries. The inclusion of steam into the package can prevent the crystallization of the medium. It is widely used in various systems such as petroleum, chemical, metallurgy and pharmaceutical to transport high temperature at normal temperature. Viscosity medium.
