Check insulation

Jacket insulation valve mainly in the petroleum, chemical, metallurgical, pharmaceutical and other types of systems to transport solidify under normal temperature high viscosity media. The series valve jacket welding between the two flanges of the valve, the valve side, is provided with a jacket bottom connecting port, due to the increase of the jacket, such valve connecting flange dimensions than the same specifications ordinary ball The connection flange freshman two specifications, but the same length of the structure on the same specifications of the valve, the jacket can only flow through the steam or other thermal insulation media, to ensure that the viscous medium can smoothly flow through the valve. BH44H / W type jacket insulation valve function is to prevent the line of medium back. Check valves are automatic valves, opening and closing pieces by the force of the flowing medium to turn itself on or off. Only for the pipeline medium flow in one direction, to prevent the media back, to prevent accidents. Applicable medium: water, oil, steam, acid media.
