Low temperature gate valve

Low temperature gate valve refers to a gate valve whose valve body, valve cover, gate plate, valve seat, valve stem and other overcurrent components have undergone special low-temperature treatment. Low temperature treatment requires the gate valve material to be immersed in liquid nitrogen at a temperature of -196 degrees Celsius for nitriding treatment. After soaking for a certain period of time, the metallographic structure of the material is thoroughly adapted to a low temperature environment of -196 degrees Celsius. Low temperature gate valve is a type of valve with a gate as the opening and closing component. The direction of movement of the gate is perpendicular to the direction of the fluid and moves in a straight line up and down with the valve stem. Gate valves can only be fully opened and fully closed, and cannot be used for regulation or throttling. The valve stem of the low-temperature gate valve produced by Shanghai Meiyanyi Pump Valve will be lengthened to avoid freezing in low-temperature environments and affecting the use of switches. It is an important type of valve with unique structural and functional characteristics, widely used in various industrial low-temperature pipelines.
