The Septum valve is used for the pressure control of BF gas at the blast furnace throat. It is installed in piping with clean or semi-clean gas.
The valve mainly consists of multiple control-duty butterfly valves with a common housing flange. Each butterfly control valve is equipped with individual control drives. Out of these multiple valves, normally one valve is used to control the flow and others are set to a desired open position as per the requirement of furnace top pressure. The shell comes with internal stainless-steel cladding to prevent abrasion due to dust particles. The actuators of the valves are positioned for easy access on both sides of the valve.
