BJ45W DC insulation globe valve insulation jacket
welding installed in the valve between the two flanges, the valve side,
the bottom of the insulation jacket is provided with two connections. DC
thermal shut-off valve is suitable for chemical industry, fertilizer
industry pipe, the jacket contains steam to prevent crystallization of
the medium, widely used in petroleum, chemical, metallurgical,
pharmaceutical and other systems to transport at room temperature will
not solidified high Viscosity medium.
