Features and benefits

All basic design features of Velan small forged steel gate valves are adapted to special service conditions at cryogenic temperatures.

● 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.
● Cleaning: All cryogenic valves are thoroughly degreased and cleaned and pipe ends are sealed to prevent contamination.
