Gate valve stem function

The valve stem is an important part of the valve. It is used for transmission. The actuator or handle is connected to the upper part. The lower part directly drives the valve core to move or rotate to realize the gate valve switching or regulating function.

Features of gate valve stem

The valve stem is not only a moving part and a stressed part, but also a sealing part during the opening and closing process of the valve.At the same time, it is impacted and corroded by the medium, and it also generates friction with the filler.Therefore, when selecting the valve stem material, ensure that it has sufficient strength, good impact toughness, scratch resistance, and corrosion resistance at the specified temperature.The valve stem is a vulnerable part, and attention should be paid to the machining performance and heat treatment performance of the material when selecting it.
