Also known as the jacket insulation valve butterfly valve, is based on common three eccentricity metal hard sealing butterfly valve in valve outside welding metal jacket, the butterfly valve is arranged in the insulation jacket interface, can cover into the steam or superheated gas, to prevent solidification at room temperature or crystallizing media. The flange insulation butterfly valves than ordinary metal hard seal butterfly valve to one to two specifications, mainly used in petroleum, chemical, metallurgy, pharmaceutical and other kinds of systems. Other features can be detailed reference metal hard seal butterfly valve. The valve also known as gate insulation jacket, mainly used in petroleum, chemical, metallurgy, pharmaceutical and other kinds of systems, high viscosity medium to transport will be solidified at room temperature. Between the valve jacket welding on valve two flange, side, bottom valve is connected with a clamping sleeve. Due to the increase of the clamping sleeve, the valve connecting flange connecting flange size to one to two specifications than the same specifications ordinary ball valve, but the length of the structure with the same specifications of the valves, clip can heat to flow freely through the steam or other heat medium jacket. Heat preservation valve is also called the clamping sleeve valve, mainly used in chemical, petroleum, pharmaceutical system pipeline, metallurgical industry, the main role is to transfer under the condition of normal temperature solidify, easy crystal medium. BJ41W insulation between two flanges welded with cut-off valve metal jacket, the jacket interface is arranged in the valve side and bottom, used to inject steam or other heat, cold medium, the medium to ensure the valve to work properly. Heat preservation stop flange valve compared with normal valve to one to two specifications.
