UNS S32760 Nickel Alloy Stem Super Duplex Valves Regulation Forging

Nickel Alloy Stem UNS S32760 Super Duplex F55 1.4501 Valve Regulation Forging

Nickel 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.

Valve Stem Seal:

Most compression packings use asbestos fibers as the base material due to its performance properties. It is essentially unaffected by most media, temperatures, and time, and is a good thermal conductor.

• The drawback of asbestos is its poor lubricity, so it is necessary to add lubricants that do not impair the performance of asbestos, such as graphite powder and mica powder. Since this mixture still has some permeability, it is also necessary to add liquid lubricants.
• Polytetrafluoroethylene (PTFE) has the smallest shrinkage rate and lowest water absorption, as well as a low coefficient of friction. It has high corrosion resistance to most corrosive media. PTFE packing can operate at temperatures ranging from -150 to 260°C. Within this temperature range, it is a high-performance, multi-purpose valve stem packing.
• Flexible graphite has the property of high-temperature resistance and also has a low coefficient of friction and resistance to most corrosive media. It can operate at temperatures up to 600°C in the packing area, so valves in high-temperature applications such as power plants and petrochemical industries use flexible graphite packing.
