Product Detail

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.
