Cast steel gate valve is a steel gate in pipeline systems that can withstand high pressure, and is cut off or released by a vertically lifting steel gate plate. It is formed by pouring high-temperature molten steel into a mold and has the characteristics of high pressure resistance and high temperature resistance, specifically designed for violent scenes.
Compared with cast iron gate valves, cast iron gate valves can withstand up to 16 kilograms, while cast steel gate valves can withstand 40 kilograms of high-pressure and 425 ℃ high-temperature steam, and are corrosion-resistant and high-temperature. They are commonly used in chemical or nuclear power plants. In contrast, cast iron gate valves are sensitive to acid and alkali and can only be used for low-pressure water/gas pipelines.
The service life of cast steel gate valves is still very long, almost hard and high-pressure. From the gushing crude oil in oil fields to the churning steam in nuclear power plants, it is all thanks to it to safeguard the safety bottom line.
