Full jacketed plug valve introduction

Full jacketed 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, and can 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.

The plug of the Full jacketed plug valve can be cylindrical or conical in shape.In a cylindrical plug, the passage is generally rectangular;In the conical plug, the channel is trapezoidal. These shapes make the design of the plug valve light, but at the same time cause some loss.Full jacketed plug valve is suitable for cutting and connecting media and for diverging purposes, but may also be used for throttling, depending on the nature of application and the erosion resistance of the sealing surface.As a result of the jacketed plug valve between the movement of the sealing surface with wiping effect, and in full open can completely prevent contact with the flow of media, so Full jacketed plug valve is usually used with suspended particles of the medium.

Full 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.Full 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.
