For rotating shafts of agitators and the like 7203 VALQUA No. Coil packing made of PTFE fiber yarns integrated with graphite and lubricating oil and of aramid fiber yarns, processed with PTFE and lubricating oil so as to form the corner section made of aramid fiber, then braided tight into a square cross section. sThis is a high performance hybrid packing that is featured with the strength of aramid fiber and with the lubrication property of graphite-integrated PTFE fiber yarn. sHaving characteristics similar to those of No.7202, but these No.7203 are best suited for shaft seals in use for rotating machines and reciprocating machines subject to still higher pressure and load. sProducts with a dimension 6.5mm or larger are available. For corrosive 7232 VALQUA No. fluids Coil packing made of PTFE fiber yarns, processed with PTFE dispersion, then braided into a square cross section. sBeing made of 100% PTFE, these are resisting to almost all fluids. sThus, these are best suited for shaft seals of rotating machines such as agitators handling corrosive fluids. Depending on service conditions, they may also be applied as shaft seals for valves and reciprocating motion machines. sNo.7232 (SO) should be used when low torque or gas sealing property is required. sThese comply with the Food Sanitation Law, and the Regulations concerning Food & Additives. For corrosive fluid valves 7233 VALQUA No. Coil packing made of PTFE fiber yarns, processed with PTFE dispersion, then braided into a square cross section. sBeing made of 100% PTFE, these are resisting to almost all fluids. sThus, these are best suited for chemical use valve shaft seals for handling corrosive fluids. sWhen low torque or gas sealing property is required, use the following products which are treated with lubricating oil: No.7233 (O) for general gas based fluids No.7233 (SO) for low temperature use of inflammable gas and liquefied gas No.7233 (FO) for gas susceptible to burn such as oxygen and ozone. sThese comply with the Food Sanitation Law, and the Regulations concerning Food & Additives. For low & medium shaft speed pumps and rotary equipment for handling corrosive fluids 7262 VALQUA No. Coil packing made of PTFE fiber yarns, processed with PTFE dispersion and lubricating oil, then braided into a square cross section. sFlexible and compatible with shafts, these are excellent in sealing property. sBeing highly excellent in chemicals resistance, these are best suited for pumps handling corrosive fluids. 41
