KO (rising spindle) ball valves are controlled shut-off valves. They are designed to stop or allow the flow of the medium by external operation, either manually or via the installed drive. This is a special type of ball valve where the ball is pressed to the seat when the valve is closing, or pressed away from the seat when the valve is opening. This design is suitable for demanding applications in various industrial sectors. It is distinguished by a long service life and serviceability. The ball valves allow the medium to flow in both directions.
Ball valves are made from carbon and stainless steel. The material type can be adjusted according to the customer´s request to optimally suit the operating conditions.
