Low temperature ball valve

Low temperature ball valve refers to a ball valve in which the valve body, ball, valve seat, valve stem and other overcurrent components are made of materials that have undergone special low-temperature treatment. Low temperature treatment requires placing the materials in liquid nitrogen at a temperature of -196 degrees Celsius for nitriding treatment. After soaking for a certain period of time, the material's metallographic structure is thoroughly adapted to a low-temperature environment of -196 degrees Celsius. A low-temperature ball valve is a valve whose opening and closing components are driven by the valve stem and rotate around the axis of the ball valve. Its working principle is to cut off or circulate the medium by rotating the ball 90 degrees. The structure of a low-temperature ball valve is compact, and it can be closed tightly with only a 90 degree rotation and a small rotational torque. The valve stem of the low-temperature ball valve produced by Shanghai Meiyan Yi Pump Valve is specially lengthened, and the inner cavity of the valve body is completely equal, providing a low resistance and straight passage for the medium.
