Cryogenic butterfly valve refers to the butterfly valve that can be used under cryogenic temperature conditions. Usually, the butterfly valve whose working temperature is lower than -40℃ is called the cryogenic temperature butterfly valve, and the butterfly valve that reaches -101℃ and below is called the ultra-low temperature butterfly valve. Especially this kind of butterfly valve with triple offset structure, because of its extremely stable design structure, reliable material selection and excellent performance, it is mostly selected and used in ultra-low temperature environment. The Triple Offset Butterfly Valve’s design also meets the most stringent international standards and can also meet the leakage rate required by users.

FEATURE:
1.Reinforced stainless steel shaft bearings for highly cycles and smooth operation at very cryogenic temperature.
2.High reliability: Safety integrity level requirements according to IEC 61508.
3.Triple offset disc rotation: provides bubble tight sealing without rubbing or galling.
4.Internal blow-out protection for prevents the shaft from blowing out under pressure.
5.Inherent fire safe function: stainless steel construction and metal seal provide inherent fire safe function.
6.The operating torque is small, the valve seat is easy to replace, and there is no need to set a limit structure.
