High pressure in boiler
WebAlthough it's the big, high-pressure industrial boilers that have the most damaging potential, industry tends to keep these units on rigorous and regular preventive maintenance schedules. Problems are caught before they lead to accidents. Boiler use, then, is an inspector's first clue in looking for potential low-water cutoff device failures. WebWith the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.
