Nickle Alloy Stem UNS S32760 Super Duplex F55 1.4501 Valve Disc Connect Actuator
Nickle Alloy Valve Stem is an important component of the valve, used for transmission. It connects to the actuator or handwheel at the top and directly drives the valve core to move or rotate at the bottom, thereby achieving the function of opening, closing, or regulating the valve.
Product Features:
The valve stem is not only a moving part and a load-bearing component during the valve opening and closing process, but also a sealing element. It is subjected to the impact and corrosion of the medium, as well as friction with the packing. Therefore, when selecting the valve stem material, it is necessary to ensure that it has sufficient strength, good impact toughness, anti-scoring properties, and corrosion resistance at the specified temperature. The valve stem is a wearing part, and attention should also be paid to the material’s machinability and heat treatment properties when selecting it.
