The cryogenic ball valve is used to cut off or connect the media in various pipelines of Class150--Class1500.the valves made of different materials are suitable for various media and different temperature.the lowest working temperature is -196℃。The driving modes include manual operation,worm and worm gear transmission,pneumatic operation and electric operation.The connection ends can be flange or welding.
Cryogenic ball valve,Size:1"~12"(DN25~DN300),Class:150~1500,Material:LCB,CF8,CF8M,304,316,Alloy steel Temperture ℃ -46~-196,Applied standard:GB /T12237,API 6D,API 608,API 598,ANSI B16.34,ANSI B16.10,Flange teyp:RF,BW,Structure:two pieces,three pieces,Operation:Manual(worm gear),Pneumatic,Suitable Medium:Propylene,Ethene,LNG.
The cryogenic ball valves are classified into cryogenic floating ball valves and cryogenic trunnion ball valves refer to the data of floating ball valve and trunnion ball valve for the product range,face-to-face dimensions,connection flange dimensions and etc.For the ball valves with temperture higher than -50℃，the long neck structure is not designed.For the ball valves with temperature lower than -50℃，the neck length is generally designed according to standard requirements or according to user requirements.
Self-relieving seat structure:In case of abnormal rise of pressure in the body cavity,automatic pressure relief of valve cavity will be effected by the relieving qualities of the flexible seat design,thus guaranteeing the safety of valve.
