A snort valve is used to regulate the flow of cold blasts going to the hot-blast stoves and vent out the excess quantity to the atmosphere through a blow-off device and silencer without disturbing the blower.
The valve mainly consists of the main control valve, exhaust valve, silencer, mechanical linkages, and drive mechanism. The main control valve is connected to the vent valve either through a mechanical linkage or a connecting rod to the disc in the exhaust valve. The synchronization between two valves is such that when the main valve is open the vent valve is completely closed and vice versa. This valve can be supplied with or without a silencer.
