Application:
GA49H-16C DN40/50 Impulse safety valve are mainly used for power plant boilers or steam pressure piping system. It can be used as a part or  used alone. When the medium in the pressure container exceedes 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 lver to ensure the safe operation of the equipment.

Structure:
1. The impulse safety valve mainly consists of body, disc, seat, lever,  hammer and so on.
