API 6D ball valve piston seal


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

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


The chemical and heat resistance of the above materials is better than rubber. They can be used in most chemical fluids, solvents, hydraulic oils and lubricating oils. Their expansibility is very small, so they can give good sealing performance for a long time.


The spring energized seal mainly use helical springs to overcome the elastic problems of PTFE, UPE, PEEK, and develops seals that can replace most of the static or dynamic (reciprocating or rotating) seals. The service temperature range can be from -196℃ to 300℃, the pressure from vacuum to ultra-high pressure 70MPa, and the moving speed can be as high as 20m / s. The spring can be used according to different service environments, springs of different materials are selected, so they can be applied to the occasion of high-temperature corrosive fluid.


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

When the pressure is more than 900LBS, an anti-extrusion ring is required.

Advantages:

1. Material compound passed API  6A FF/HH Immersion Testing;
2. High load helical wound spring with small deflection range;
3. With small amount of elastic deformation, suitable for some closed grooves;
4. Rigid spring acts as energizer to resist low-temperature shrinkage;
5. NACE approved energizers available for oil and gas use.
