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.

Swivel joint ball plug is working together with hammer union seals, to seal the balls of high pressure elbows and grease.

In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.

DAS Compact Seal is a double-acting seal and guiding element comprising an elastomeric profile seal ring, two back-up rings and two guide rings.

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.
