New and quite special: the FKM compound Vi 840, which is flexible at low temperatures, has been successfully tested according to DVGW DIN EN 682 (type GBL). What’s more, this material has low temperature flexibility of more than -40 °C, which means it therefore fulfils the requirements of DIN EN 14141. A combination of properties that make this special FKM compound something really unique.

The elastomer innovation Vi 840 meets central industry requirements of having a suitable level of low temperature flexibility, and conforms to the DIN EN 14141 standard. With a TR-10 value of -40.1 °C, COG’s world first is suitable for use at temperatures of right down to -46 °C, therefore fulfilling the important API 6A and 6D standards. Furthermore, these properties can be proven, and are documented to DIN EN 13787 standard. In short: the Vi 840 FKM compound is a real highlight for the valves sector and a top compound for the gas industry.

Vi 840’s properties

  • Excellent material for use in the natural gas industry
  • Certification tested according to DVGW requirements:
    • DIN EN 682 test (type GBL)
    • DIN EN 13787
  • Fulfils:
    • DIN EN 14141
    • API 6A and 6D standards
  • Extremely wide operating temperature range, from -46 °C to +200 °C Excellent low temperature flexibility: TR-10 value -40.1 °C
  • Very good low temperature compression set

Vi 840 – Best measurements when it comes to compression set

With the Vi 840 FKM compound, COG proves its materials expertise in stunning fashion: the Vi 840 compound performed excellently in the DIN EN 682 test (type GBL). It was clearly able to exceed the target values for compression set. When it comes to low temperature flexibility, this COG development sets new standards.

All components of this FKM material fulfil the DIN EN 682, DIN EN 14141 and DIN 13787 standards, as well as the valves and valve fittings industry’s API 6A and 6D standards. The innovative Vi 840 FKM compound is equally suitable for use in pig traps, gate valves, ballcocks and other regulating valves – a true all-rounder for applications in the oil and gas industries.
