50API 6D ball valve piston seal
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.

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.
JST FHR series is made of a helical wound spring and a polymer jacket, which is mainly used for rod.
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a seat seal.
The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
ptfe wear strips can keep the piston centered as well as preventing metal-to-metal contact.
We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
