Pressure systems at work: A brief guide to safety INDG261

Safety valve is used to guard the boiler against the excessive high pressure of steam inside the drum. If the pressure of steam in the boiler drum exceeds the working pressure then the safety valve allows blow-off the excess quantity of steam to atmosphere. Thus the pressure of steam in the drum falls. The escape of steam makes a audio noise to

Rules and Regulations for Boiler and Pressure Vessel

With 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.

Safety - If the internals of the APT failed, the safety valve would still relieve the pressure in the vessel even if the control valve were shut. Operation - There is less chance of safety valve 'A' simmering during operation in this position,as the pressure is typically lower after the control valve than before it.
