Bidirectional high-pressure ball valve seat seal
In recent years, with the continuous development of petrochemicals and shale gas, and the widespread application in the air separation industry, liquefied petroleum gas, low-temperature ethylene industry, especially natural gas projects, the demand for ball valves in engineering projects has been increasing, which has also led to an increasing demand for ball valve seals. At present, ball valve sealing with unidirectional sealing is the majority used in the market. JST has developed a high-pressure bidirectional sealing component, which can provide you with feasible bidirectional sealing solutions for ball valve high-pressure equipment.
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.
The product fully meets the pressure working conditions requirements of the current 6D ball valve, ranging from 0 to 47MPa, with good sealing performance, and the sealing element will not extrude and deform. After use, the product maintains a good structure. Under bidirectional pressure (high pressure) ambient temperature, there is no leakage at each stage, and the product has a service life of over 1 year.
Application：
1. 6D ball valve bi-directional seat and extension can be used for other bi-directional pressure sealing
2. Bi-directional pressure bearing piston or rod sealing to reduce product deformation and ensure sealing effect

The FHB seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange internal face seal.
The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.
JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.
The ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.
The BVR series is made of a canted level spring and a polymer jacket, which is mainly used as a stem seal.
