Cryogenic Gate Valves

2 to 24 50 mm to 600 mm asme class.
Cryogenic gate valves. Prevent stem unstable structure optional soft seal. They prevent leakages and excessive pressure build up even in extreme. 2 to 36 50 mm to 900 mm asme. Different types of cryogenic valves are designed to meet the specific arrangements and job environments.
Powell valves manufactures asme class 150 200 cryogenic valves in differing sizes types valve materials and trim materials. To 2 gate valve class 200 600. The gate valves are manufactured in stainless steel. Cryogenic valves are better transmitters when efficient heat transfer is required at a varied temperature range.
Why use cryogenic valves. 2 to 54 50 mm to 1350 mm asme class. All basic design features of velan cast steel gate valves are adapted to special service conditions at cryogenic temperatures. The cryogenic gate valves are available in sizes from dn25 to dn100 and secure pressures up to 50 bar at operating temperatures of 196 c to 120 c.

With herose cryogenic gate valves the flow rate is three to five times higher than with globe valves of comparable size. Cryogenic valves obtained their name from the branch of physics pertaining to materials. Cryogenic globe valves cryogenic gate valves nps 1 2 42 dn 15 1050 class 150 2500 pn 20 420 extended bonnet low emission packing stellite overlay on wedge and seat ring bleed hole between upstream and backseat to prevent the pressure increase of body cavity. 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.
Parker bestobell s cryogenic gate valves feature an innovative flexible wedge design with minimal leakage. The cryogenic gate valves are available in sizes from dn25 to dn100 and secure pressures up to 50 bar at operating temperatures of 196 c to 120 c. Please find your cryogenic gate valve in the product choice below. 150 to 600 design standards.
Designed to operate efficiently even at low valve pressure drops these valves are lightweight and suitable for industrial gas transportation. 2490 2467 1973.
