Can a plug valve be used in steam pipes?

The sealing performance of the plug valve seems to be poor; it doesn’t seem very suitable for use. ——The plug valve is the earliest type of valve to have been used in history. Due to its simple structure, rapid opening and closing, ease of operation, and low fluid resistance, it is still widely used to this day. It is currently mainly used in low-pressure applications, with small diameters and medium temperatures.

Gate valves and globe valves are commonly used for steam pipelines. It’s not clear whether a plug valve is suitable, as it has never been used in this way; however, the high cost makes it unnecessary.

I don’t know. The voltage tolerance is too low, and the sealing is inadequate.

Okay, then I’ll ask the customer to avoid using ball valves and opt for gate valves instead. Thank you all for your responses.
