6610CN
Seal packing
Low sliding friction type seal packing made from flexible graphite sheet that has been formed into a ring, whose internal periphery has undergone lubricating treatment with PTFE and fine graphite powder.
This packing is used for nuclear applications, to control chlorine ion concentration.
This packing uses no metallic materials. It features low valve stem sliding friction, in addition to sealability and chemical resistance.
Fluid temperature: -200 to +400°C (*)
(*) Packing temperature must be kept at 350°C or less.
Operating temperature range is different from that for No. 6610CL.
Pressure: 77.6 MPaG max. (Class 4500)
pH: 0 to 14
Chlorine ion concentration: 100 ppm or less
