One of the biggest valve was the SNORT throttling valve with weight of 8 tons. Basically it is a set which is composed of throttling valve with diameter of 1400 mm and exhaust device called “Silencer”. The total height of the device reaches over 6 meters.

SNORT will be assembled in the inlet pipe of cold air to the air heater. Silencer should be in a vertical position above the body of the throttling valve. Due to the size and weight of the entire device the assembly in the metallurgical operation is not possible without a crane.
