Spring energized ball valve seal

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 FHP series is  made of a helical wound spring and a polymer jacket, which is mainly used for piston.

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.

UNS UHS is a lip-seal which can be used for both piston and rod .

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions.   The chevron seal stack material could be PEEK, modified PTFE and spring.

Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.
