Use：

GA49H-16C DN40/50 impulse safety valve are mainly used for power plant boilers or steam pressure piping. It can be used as a part or alone. When then medium in the pressure container exceeds the allowable value, the disc will open to discharge the overpressure steam, and when the pressure drops to a certain value,the disc will quickly close the valve by the heavy hammer on the lever to ensure the safe operation of the equipment.
