PTFE guide and wear strip

V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.

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.

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 stem seal.

The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a seat seal.

JST FHR series is  made of a helical wound spring and a polymer jacket, which is mainly used for rod.

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.

The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.
