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.
