GR80SGRTA LUFT VDI 2440 Approved

This is a valve packing made from very pure expanded graphite yarn with a special nickel alloy reinforcement. It is suitable for all uses that are compatible with graphite. Its special composition ensures excellent resistance to high pressures and temperatures with low weight losses, guaranteeing low emission levels.

• Temperature
  -200°C to 650°C, with a limit of 450°C for weakly oxidising fluids and hot air.

• Pressure range
  It overs all the pressure classes up to API 10000 psi.

• PH Range
  0 to 14, except for strong xidants.

Approvals

• TA LUFT VDI 2440
• Weight Loss Test EN 14772, section 6.7

GR80SGR, the TA LUFT packing
Elastic, resistant and simple to install
Elasticity, wear resistance, ease of installation, low emission, extrusion resistance, low oxidation rate, low friction coefficient, non-corrosive. GR80SGR was designed and made to achieve all of these goals!

Low oxidation rate and friction coefficient
GR80SGR is made from very pure materials, ensuring a low weight loss at high temperatures. Thanks to the special thread-by-thread impregnation with corrosion inhibitors and solid lubricants, GR80SGR keeps stems intact and reduces the need for re-tightening during service.

Low Emission
GR80SGR is a packing that meets the requirements of TA LUFT VDI2440, thanks to its elasticity and low permeability.
