Spring energized ball valve seal


Spring energized seal:
JST FHR series is made of a helical wound spring and a polymer jacket, which is mainly used for rod.

The polymer jacket's material includes virgin PTFE, filled PTFE, UHMW-PE, PEEK, etc.

The helical wound spring's material includes Stainless Steel, Elgiloy, Hast Alloy, etc.


Considerations when determining whether to use standard polymer seals or spring energized seals include:

  • Temperature (possible maximum / minimum values of working and environment)
  • Working pressure (not necessarily the maximum pressure in the system)
  • Speed (moving speed)
  • Medium (chemical compatibility: especially important in case of corrosive medium)
  • Friction level and wear
  • Environment (e.g. grinding conditions)
  • Application and operation of equipment
  • Sealing cavity structure

Advantages:

1. Material compound passed API  6A FF/HH Immersion Testing;
2. High load helical wound spring with small deflection range;
3. valve lip seal With small amount of elastic deformation, suitable for some closed grooves;
4. Rounded lip profile for easy assembly;
5. Wide range of cross-sections and diameters available;
6. NACE approved energizers available for oil and gas use.
