OnC SegmentValve 500 segmented ball valves are an optimal solution for the paper industry and can be used with consistencies up to 18%. They can be pneumatically or manually activated with hand gearing/hand lever. The drive itself can be optionally equipped with a security function (spring closes, spring opens). OnC SegmentValve 500 is also available as a control valve with VP500 (Voith positioner). The diameters available range from DN 25 to DN 700; the intermediate flange is available up to DN 250. The seat ring of the OnC SegmentValve 500 is made of PTFE53, optionally of metal. For high differential pressure, the low-noise version would be the preferred option, which controls the steam and provides for decompression. The V-groove version should be used for minimal flow rates.
OnC SegmentValve 500 is used for application in stock preparation up to the dryer section and is also suitable for high contaminant contents such as reject. A metal seat ring should be used.
