50High pressure ball valve seat seal
The spring energized seal can select different spring forms and sealing lip designs according to the applications such as dynamic, static, internal and external pressure, resulting in impassable sealing force and compression deformation. The spring force will affect the performance, friction and wear performance of the jacket. The compressible stroke determines the compensation ability of the jacket for the wear of the sealing lip and the dimensional tolerance variation of the sealing groove.
Customized products can be developed according to customers' needs.

The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.
The spring energized seal is a high-performance Teflon seal with a special spring inside.
The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.
Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.
Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.
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.
Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.
