Our tight shut-off valve OSK offers an economical solution, for instance for piping systems conveying liquids or gases. Its compact design and flexible welded construction make it suitable for a wide range of applications.

The OSK’s double-eccentrically positioned valve disc and the hydrodynamically optimised soft sealing system allow the medium to flow through homogeneously without dead zones. Low wear is guaranteed by two factors: the continuous valve seal is highly resistant to hydrodynamic forces and low friction is gentle on the sealing system. Furthermore, rubber-coated valves or those made of stainless materials are available to ensure resistance to corrosion. A seawater model is also available.
