Manual Cast Steel Ball Valve
Introduction:
The manual cast steel ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. The valve body is made of cast steel, and it only needs to be manually rotated 90 degrees with the handle for quick opening and closing. Applicable temperature -46 degrees to 425 degrees, mainly used in petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.
Features:
Its drag coefficient is equal to that of a pipe section of the same length. The thrust bearing reduces the friction torque of the valve stem, so that the valve stem can work smoothly and flexibly. The valve seat has excellent sealing properties. The sealing ring made of elastic material (such as Teflon) is easy to seal, and the higher the medium pressure, the better the valve sealing ability of the ball valve. The valve stem seals securely. Since the stem only rotates and does not move up and down, the packing seal of the stem is less prone to damage.
