Ramén KS-1A

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.

We recommend other material executions in case of high velocity and/or temperature and if cavitation will occur. Optional O-ring seals and trim variations are available, please consult Ramén. Always consult Ramén for valve sizing and material selection. General technical bulletins and data sheets are available for complete technical specification. Do not hesitate to contact Ramén for clarification.
