Product Description

Cryogenic Ball Valve

    Application

    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 -196ºC . 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 -50ºC, long neck design is seldom adopted. For valves with working temperature below-50ºC, the neck length T shall be 250mm, or shall be decided as per our own design and calculation.

     CHAODA valves group is specialized in manufacturing Stainless Steel Lift Plug 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.

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD. is a wholly owned subsidiary of CHAODA VALVES GROUP CO.,LTD.With  Chaoda valves group quality management and safety system(Get the approvals of ISO9001,ISO14001,OHSAS18001,API600,API6D,CE/PED,API607,API6FA,ISO15848-1, TS  certified),top level developing team(Provincial Key Enterprise research Institute,Provincial Key Enterprise Technology  Innovative Group, Provincial Enterprise Technology Center),advanced machining equipment, well chemical analyst and inspection equipment(Optical Spectrometer, Helium low emission tester, High & Low temperature performance equipment and etc)we could provide our clients with perfect products and satisfied service.

Cryogenic Ball Valve product description

 Cryogenic Ball Valves(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 CHAODA 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. 

    CHAODA GROUP WENZHOU E-BUSINESS CO.,LTD.is wholly owned subsidiary by Chaoda Group,Professional sales CHAODA group products,CHAODA valve products.CHAODA valves won the reputations of Zhejiang Famous Trademark,Zhejiang Famous Brand,Zhejiang Famous Exporting Brand and also enjoys prizes of 101 National Patent.
