Detail Information

Cryogenic Butterfly Valve

The Cryogenic Butterfly valve is suitable for service of working temperature down to -196℃, such as LNG, LPG industry. Three eccentric laminate hard seal flange butterfly valve is a long-life, energy-saving butterfly valve. Its structure adopts the three-dimensional core principle design, the valve seat adopts the laminate stainless steel with graphite structure of hard and soft sealing compatibility, with exquisite processing and advanced technology. This product is composed of valve body, butterfly disc, laminate seal as valve seat, valve stem, transmission mechanism and other main components. It is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage pipeline.

Cryogenic Butterfly Valve-Features

There is three eccentric (offset), the first eccentric, the shaft deviated from the centerline of sealing face; The second eccentric, the shaft deviated from the centerline of pipe and valve; The third eccentric the distinctive included angle between oblique taper angle of eccentric seat and centerline of pipe, thus making seat completely disengaged from the sealing ring during the whole process of open and close. This structure not only uses cam effect, but also eliminates the possibility of abrasion and leakage.


Cryogenic Butterfly Valve


1. Elastic property of composite metal sealing ring to perform zero leakage.
2. Torque seal to ensure two -way zero leakage.
3. STL one piece hard surface seat may adapt to many working conditions, which is featured by long service life and easy maintenance.
4. One piece cast body, face to face dimensions conforming to ISO 5752, ASME B16.10 and API 609,replacement to high performance butterfly valves and other types of valves, easy and flexible installation.
5. The extension bonnet provides efficient cold insulation, minimizing heat conduction and transfer from cryogenic flow, while preventing the exposure of valve packing to cryogenic media and providing a secure seal.
