Description
Dembla Cryogenic Ball Valves can withstand and operate effectively at extremely cold temperatures up to -196oC. 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.
Features
Height of the extended bonnet suitably designed to keep away stuffing box from cryogenic surfaces. This avoids the failure of seals due to low temperature effect.
