Cryogenic service triple offsets butterfly valve

 

  

>> Basic information:

Class  150Lb-900Lb  End  RF, BW  Structure  Triple Offsets  Actuator  Worm, Electrical, Pneumatic  Related standards  Design  API 609, BS6364  Test  API 598  End  B16.5/B16.25  Top flange  ISO 5211  Medium: Special Cryogenic service medium


>> Introduction:

  1. Cryogenic service butterfly valve structure is triple offsets, working temperature can be-46℃,-101℃,-196

  2. As per cryogenic service butterfly valve service requirement, we use complete different design theory, optimize design solution about different material extend rating in low temperature scope, and keep seal effort is well.

  3. Valve body has to be passed RT test before into produce process, RT test is Class II as least; all the welding on the body has to be followed by ASME IX requirement, and be traced in files.

  4. Butterfly valve is working in cryogenic condition, all valve wet part will be pass deep low temperature heat treatment, and it is protected during producing.

  5. The extend stem length dimension is as per real working temperature condition, and target is outside temperature can’t effect pipeline working.

  6. All cryogenic service butterfly valve’s testing & inspection is strict as per quality control procedure, so it’s delivery time is slow than normal triple offsets butterfly valve delivery days.
