What if it is suddenly determined that the steam valve is still open, causing losses?

What is this process or procedure? No, add an air supply valve to the steam.
It’s a steam electric control valve that is interlocked with a temperature sensor; when power is lost, the steam valve remains open and continues to heat, causing the pipes to soften. Is there any good method?
Optimize it from the instrumentation side; just replace the steam valve or set it to turn off in case of a fault
It must have been a sudden power outage. Edit it yourself and everyone will understand. . . . . .
Adding a temperature-sensing series control should do it.
Sir, what does temperature-based series control mean?
For simple cases, just replace the control valve that is in the closed state; for more complex situations, install a UPS
Temperature interlocking, FC valves, etc
A pneumatic valve that closes when the air is released. Power loss – the solenoid valve releases air, and the valve closes.
The motorized pump will stop operating when the power is cut off. You should set up a interlock between the signals of the important pumps and the air inlet valves; the air inlet valves should open when air is supplied, and they will close automatically when the power is lost.
