Extended bonnets with sufficient gas column length, usually specified by customer, are supplied for all valves to keep stem packing at sufficient distance away from the cold fluid to remain functional.
Solid CoCr alloy wedges on NPS 1⁄2 – 2 (DN 15–50) valves operate with no galling in cryogenic service.
