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.
TECHNICAL DESCRIPTION:
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.
SPECIAL FEATURES
- Water spray nozzles can be provided to flush the accumulated dust particles.
- Valve internals can be coated/painted with ceramic coatings.
