Ramén KS-1A

Material Execution 1A
– Soft seated Control Valve with hard chromed ball sector DN 25 – DN 300

The Ramén Ball Sector Control Valve in material execution 1A is a stainless steel AISI 316 soft seated Control Valve with a carbon/graphite reinforced PTFE seat ring and a hard chrome coated ball sector.

KS-1A is recommended in cases where the purity of the fluid is unknown or if the pressure and/or temperature is not fully known. This valve with PTFE seat is tight in closed position and may easily be converted on site into a metal seated valve with hard chromed ball sector element refer to KS-1B. KS-1A is excellent for wastewater, fibre suspensions and other abrasive media. KS-1A is also the choice for a tank bottom valve (operated on liquids, slurries or dry powder) where optimum shut off tightness is required and the soft seat is exchanged when needed rather than accepting a metal seat shut off leakage rate.

KS-1A is recommended in cases where the purity of the fluid is unknown or if the pressure and/or temperature is not fully known. This valve with PTFE seat is tight in closed position and may easily be converted, on site, into a metal seated valve. The metal seat can, in combination with the hard chromed ball sector surface; handle particles and higher pressure drop (velocities). KS-1A may also be the choice for a tank bottom valve (operated on dry powder) where optimum shut off tightness is required and the soft seat is exchanged when needed rather than accepting a metal seat shut off leakage rate.

The Ramén Ball Sector Valve can be used for temperatures from -40°C to +200°C (+250°C). The exact temperature range is always depending on pressure, media and sealing material. Always contact your valve supplier if pressure, media or sealing material changes.
