China Jacketed non-lubricated plug valve manufacturer,factory and supplier, Jacketed non-lubricated plug valve is suitable for opening and closing with nominal pressure PN1.0 ~ 10.0MPa, Class150 ~ 600, JIS10K ~ 20K, working temperature -29 ~ 425℃ (carbon steel), -40 ~ 500℃ (stainless steel) pipeline, Jacketed non-lubricated plug valve keep heat and prevent medium crystallization. Different materials can be used for heavy oil, glue, nitric acid, acetic acid, strong oxidizing medium and urea, etc.

Jacketed non-lubricated plug valve is installed in the valve body with a layer of metal jacket, through the injection of steam, heat conduction oil, cooling water, cool air and other metal jacket, so that the medium of the valve body at room temperature, heating, cooling and other conditions, to achieve the required temperature, play the role of heat preservation or cooling.Jacketed non-lubricated plug valve is used in the room temperature will solidify high viscosity, steam or other heat preservation, cold media, to ensure that the medium in the valve can work normally.
