How does the pilot safety valve work?
The safety valve with power assist device uses a power assist device to force the safety valve to open when the opening pressure is lower than the normal opening pressure. This kind of safety valve is suitable for occasions where the opening pressure is very close to the working pressure, or where the safety valve needs to be opened regularly for inspection or blowing off sticky or frozen media. At the same time, it also provides a means of forcibly opening the safety valve in an emergency.
