Compact external dimensions, short face-to-face dimensions at all pressure ratings, and low weight make the OSK an economical valve for pipelines transporting liquids or gases. The streamlined, duo-eccentrically mounted disc, together with the conical sealing system, ensure a smooth-flow passage.
The continuous seal provides tight shut-off and low friction and wear characteristics. The shaft runs in self-lubricated bearings housed outside the flow stream and sealed against the media by O-rings or graphite rings. Rubber-lined carbon steel valves and anti-corrosion materials guarantee low maintenance, versatility, and long service life.
