insulation cut-off valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical and other transmission of high viscosity media system, curing at room temperature. It is dc jacket insulation, and it is welded to the valve between the two flange insulation cut-off valve, the valve side and bottom of the two connection interfaces are equipped with heat insulation sleeve. Dc insulation cut-off valve particularly applicable to chemical, chemical fertilizer pipes. The connotation of the jacket can prevent the crystallization of medium. Thermal insulation ball valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other systems. Insulation valve structure introduction to the valve and valve body in a layer of metal shell welding by steam, thermal oil, cooling water, air conditioning, etc into the metal casing, make the body of the medium at room temperature, heating and cooling conditions meet the temperature, have the effect of heat preservation or cold storage. Thermal insulation valve will be high viscosity curing at room temperature, heat preservation, cold media such as steam, guarantee the normal work of the valve of medium. Insulation valve is the role of the principle of the heat preservation valve has good heat preservation and cooling characteristics, and the diameter of the pipe diameter, and can effectively reduce the heat loss of pipe medium. It has good heat preservation and cooling characteristic, and can effectively reduce heat loss in the medium in pipeline. Insulation valve is widely used in petroleum, chemical, metallurgical, pharmaceutical and other system, effectively reduce the heat loss in the pipe, prevent the crystallization of the medium, solidification and other similar phenomena. Insulation valve is used to make the material in the heat preservation valve when the temperature is high or low to medium heat preservation effect, make the medium not condensation or attached on the body, make the normal operation of the opening and closing of the Industrial Valves.

Every day of the year, there is some city or town in the world that is changing over to for resilient seated valve.
