What are the commonly used materials for valve electric devices?

To select the correct valve material, the engineer must consider the flow media, pressure, flow rate, and intended purpose, while the temperature of the flowing medium and the operating environment are factors that need to be considered for the valve material. Corrosion can occur at higher temperatures. In addition, temperature can cause different materials to expand and contract at different rates, which can cause leakage problems, excessive restraint stress on valve elements, or failure episodes.
Components such as valve actuators, valve seats and valve bodies are usually provided in materials that provide different ranges of corrosion, temperature and wear resistance. Commonly used materials include:
Ductile iron: Due to its low cost and availability, ductile iron provides the additional benefit of easy shock absorption. The downside is that ductile iron has poor corrosion resistance.
Brass and Bronze: Brass and bronze valves are also available at low cost and are readily available. Increased corrosion resistance compared to ductile iron.
3.316 stainless steel: known for its excellent corrosion resistance, 316 stainless steel valves are more expensive than cast iron, brass and bronze valves.
4. Monel alloy: nickel-copper alloy Monel has excellent corrosion resistance. It is usually used for the covering of valve trim.
5. Inconel nickel alloy: Inconel is an alloy of nickel, chromium and iron, used to deal with corrosive media at higher temperatures.
