Cryogenic Trunnion Mounted Ball Valve - Series 8200
Series - 8200
Dembla cryogenic ball valves can withstand and operate effectively at extremely cold temperatures up to -196°C. Cryogenic ball valves are bi-directional, tight shut-off used in low-temperature applications with hazardous and non-hazardous environments. The unique bonnet design allows only a thin layer of flow between extension ID and stem OD, resulting in minimum energy loss along the extension.
