Material Execution KSG/KSGF
– Rubber Lined Ramén Ball Sector Valve
DN 80 – DN 200

The KSG is a rubber lined valve that offer extended resistance to wear and tear in the valve for slurries, gravel, iron ore and other highly abrasive media. The natural rubber used on the ball sector and in the house gives a valve with very long life time in any situation with maintained throttling characteristics. When a high end control valve is needed for tough media the Ramén KSG valve can be used in wafer and flanged design.
