  • Description:China jacketed plug valve manufacturer,factory and supplier for soft seated and metal seated plug valve.
Metal seated jacketed plug valve is used for high temperature medium 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, Metal seated jacketed 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.

Metal seated jacketed 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.Metal seated jacketed 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.
