Rapid Gas Decompression O ring

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.

KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.

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

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.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.

JST's ESU series stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance.

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

OD Face Seals for gate valves are spring-loaded, pressure-energized lip seal that improve gate and seat service life.
