Features and benefits

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

Available in piston bolted cover, ball type bolted cover, and swing check bolted cover.

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.
● Solid Stellite 6 wedges on NPS 1⁄2–2 (DN 15–50) valves operate with no galling in cryogenic service.
● Kel-F inserts (optional) for piston and swing check discs.
● Cleaning: All cryogenic valves are thoroughly degreased and cleaned and pipe ends are sealed to prevent contamination.
