Features and benefits
All basic design features of Velan cast steel gate valves are adapted to special service conditions at cryogenic temperatures.
ADDITIONAL DESIGN FEATURES:
● 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.
● Flexible wedges with CoCr alloy seating faces for cryogenic service.
● Cleaning: All cryogenic valves are thoroughly degreased and cleaned and pipe ends are sealed to prevent contamination.
