OnC SegmentValve 500 is a segmented ball valve that is optimally suited to all consistency and pressure controls. It can be used for water, stock/reject and steam.
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.
Model overview OnC SegmentValve
OnC SegmentValve KVT/KVTW/KVX/KVXW
Ball segment valve Wafer
SV500.KVT SV500.KVTW SV500.KVX SV500.KVXW
Control and on-off function. The valve types KVT and KVTW are a sandwich Wafer design version with centrically mounted shaft, while KVX and KVXW dispose of an eccentrically mounted shaft.
Low noise version for high differen -
Abrasion-resistant surfacing (stellite)
Wafer versions according to DIN/EN
Water, stock or rejects up to medium consistency (18%) as well as steam > 200 °C with eccentric shaft
OnC SegmentValve KVTF/KVXF
Ball segment valve flanged
Control and on-off function. Type SV500.KVTF is a flanged version with a centrically mounted shaft, while KVXF is flanged with an eccentric design.
Various seat rings available
Abrasion-resistant surfacing (stellite) available
Flange versions according to DIN/EN
Optional ANSI drillings possible
Water, stock as well as steam > 200 °C with eccentric shaft
OnC SegmentValve KVM
Ball segment valve with V-groove
This Ball segment valve is for use at high fibre concentrations of up to 15% consistency. The V-groove design prevents dewatering at small opening angles.
Control valve after MC pump
OnC SegmentValve Low noise versions
Ball segment valve low noise
SV500 KVTW LN SV500 KVX WLN SV500 KVTF LN SV500 KVXF LN
Especially designed for control purposes at high differential pressures. The ball segment is equipped with a low noise trim to distribute the pressure drop across the valve, lessen pressure recovery and reduce noise as well as potential cavitation damage usually generated in standard models.
Wafer design KVTW/KVXW LN DN50–250; PN20–50
Flanged design KVTF/KVXF LN DN50–400; PN20–50
Gases, steam, water and thin stock
OnC SegmentValve High pressure version
Ball segment valve PN100 high pressure
Especially designed for control and on- off function at high pressures.
Pressure rating PN100
