API 623 Cast Steel Cryogenic Globe Valve – Features & Benefits
As a leading Velan Valve Supplier, Distributor, and Stockist, we provide premium API 623 Cryogenic Globe Valves engineered for extreme low-temperature applications. These valves combine Velan’s renowned forged steel globe valve design with specialized cryogenic enhancements for unmatched reliability in LNG, industrial gas, and sub-zero fluid systems.
Key Features & Benefits
1. Extended Bonnet Design
-
Gas column length (customer-specified) ensures stem packing remains functional by distancing it from cryogenic fluid.
-
Prevents freezing and maintains sealing integrity in -196°C (-320°F) conditions.
2. Anti-Galling Solid CoCr Alloy Wedges
-
NPS ½ – 2 (DN 15–50) valves feature cobalt-chromium (CoCr) wedges for galling-free operation in cryogenic service.
-
Ideal for LNG, oxygen, nitrogen, and argon applications.
3. Optional Kel-F Inserts for Globe Discs
-
Enhanced sealing performance with PTFE-alternative Kel-F for ultra-low-temperature resilience.
4. Ultra-Clean, Contamination-Free Assembly
-
Degreased & precision-cleaned internals per MSS SP-93 standards.
-
Sealed pipe ends prevent particulate ingress during storage/transport.
