Floating type Cryogenic Ball Valve Forging Split Body Anti - Static Device

Good quality Trunnion Ball Valve for sales
Good quality Trunnion Ball Valve for sales
Really good performance valves with completitive cost, I hope both parties will work for longer.

—— Rashid Lodhi

Good after sale service, I really appreciated that the each step maintenance instruction is very detailed and good for my end user even they do not know valves at all.


Wesley from Kelite Group was very perfessional on handling our FAT, 3.2 certification, 3rd party inspection and accompany my clients to aduit each supplier, also a good driver for lasts more than 12 hours driving to pick up my clients, impressive!

low temperature ball valve


cryogenic gate valve

Cryogenic valve of low temperature ball valves, casting and forging material


Forging split body, full bore/reduced bore, trunnion mounted, double block and bleed, single or double piston effect, anti-blow out stem, anti-static device, fire-safe certified to API-607/6FA/ISO 10497, spring loaded Seats, sealant injection, NACE MR-01-75, NYLON, DEVLON&PEEK seat inserts, designed and tested according to ASME B16.34, BS5351 and API-6D,API-6DSS, API 6A.



The cryogenic ball valve is applicable to different pipeline of Class150~Class1500, PN16~PN100, JIS10K~JIS20K.By adopting different materials, the cryogenic ball valve is applicable to different working temperature and medium.The minimum temperature for the ball valve is -196℃ . The operation of the ball valve can be manual operated, gear operated, pneumatic operated and motor operated. The end connection usually is flanged ends. However, the welded ends are also optional.


Product range

The cryogenic ball valve has two types: floating ball and trunnion mounted ball. For their range, face to face dimension and flange dimension, please refer to the corresponding data of common floating ball valve and trunnion mounted ball valve. For valves with working temperature above -50℃, long neck design is seldom adopted. For valves with working temperature below-50℃, the neck length T shall be 250mm, or shall be decided as per our own design and calculation.


Kelite is specialized in manufacturing cryogenic ball valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.


The cryogenic ball valve has two different types: Floating type cryogenic ball valve & Trunnion mounted type cryogenic ball valve. As the structure of cryogenic ball valve is very similar with plug valve, so it's also called by some people Ball shaped plug valve. The sealing element of Cryogenic ball valve is composed with one ball & two seat ring. PTFE is the most common material used for seat. Ball valve has been the valve with quickest development for its advantages of smallest flowing resistance, quick opening & closing, good sealing and etc.

Cryogenic Ball Valve product description

Cryogenic ball valve (Generally flanged connection, but butt-welding is optional) are suitable for use on various kinds of pipeline from Class150 To Class900, PN16 To PN100 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs.


The selection of material of valve for LNG medium is very important. Unqulified material may result in external leakage of body or internal leakage of seat; What's more, if the mechanical property, strength & stiffness of componet could meet the requirement, fracture may happen which would result in even explosion because of the leaking LNG. All the main components of Stainless steel Cryogenic Ball Valve developed by KELITE would be treated in cryogenic treatment medium for 2~8 hours to release the material stress after raw machining to ensure its stability under cryogenic condition. Precise manufacturing dimension should be guaranteed to ensure no leakage from the deformation caused by the temperature changing.


Cryogenic Ball Valve product features

Cryogenic ball valve is used for low temperature working condition, especially for some hazard media, such as liquidized natural gas. Our company has been experienced in the design, manufacturing, inspection and test of cryogenic ball valve.

Choose for material

Common steels are brittle in the cryogenic condition. So, the key point for the design and production of cryogenic ball is to select proper body material according to the minimum working temperature of the ball valve. To ensure the material suitability under the low temperature condition, the material adopted shall be impact tested according to the standard requirement. The packing, gasket, bolt and nut shall also adopt the materials suitable for low temperature condition.


Design and manufacturing features

Being required by the standard, the long neck design is usually adopted for the ball valve below -50℃. The long neck design can keep the heat at the packing position and ensure the reliable sealing performance of the valve packing. The length of the neck complies to the standard, but, can be also changed as per the customer's request in the contract.

For cryogenic ball valve, if the valve is at closed position, the cryogenic liquid stayed in the cavity of the valve will be gasified and expanded when the temperature gets rising. This will cause the unusual high pressure in the cavity, and maybe break the valve. To avoid such dangerous accident, our ball valve has self-relief function for the cavity pressure. When the pressure in the cavity unusually rises, the medium in the cavity will push the seat to relive the pressure by it's own force.Such design will endure the safety of the valve.

The ball valve can be cryogenic tested if it is specified in the contract. The operating torque, sealing performance and other data can be obtained and checked by the test.

The spare parts of the valve shall be cryogenically treated to ensure their dimensional stability under the cryogenic condition.


KELITE cryogenic ball valve has the features of Good sealing, reliable, safety and long life span.


Cryogenic Ball valves developed by Kelite have following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc.

  1. Pressure relief hole is set on the ball of Cryogenic ball valve.
  2. Ceramic filled material is used for gasket.
  3. Light weight and small dimension is adopted in order to reduce the heat loss especially under cryogenic condition.
  4. Long neck stem design is used to keep the heat at the packing position and ensure the reliable sealing performance. The length of extended neck is decided per design, calculation & testing.
