          Cemented Carbide Valve Components


          The valve stem is an important part of the valve, which is used for transmission, connecting the actuator or handle, and directly driving the valve core to move or rotate below to realize the valve switch or regulation.

          The valve stem is not only a moving part and a stress part, but also a sealing part in the opening and closing process of the valve. At the same time, it is impacted and corroded by the medium, and it also rubs against the filler. Therefore, when choosing stem material, it is necessary to ensure that it has sufficient strength, good impact toughness, abrasion resistance and corrosion resistance at the specified temperature. The valve stem is a fragile part, and the mechanical and heat treatment properties of the material should be paid attention to when selecting the valve stem.
