Septum Valve
- 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.
