How to Select the Right Cryogenic Valve for LNG Service
Correct valve selection depends on operating duty, not only size and pressure class. Use the guide below as a starting point, then confirm with our engineering team.
Fast Shut-Off
Choose a cryogenic ball valve for frequent cycling, loading/unloading, pump isolation, and ESD duties requiring rapid quarter-turn shut-off.
Large-Bore Isolation
Choose a cryogenic gate valve for tank-bottom and main transfer lines where full-bore flow and low pressure drop are priorities.
Flow Regulation
Choose a cryogenic globe valve for BOG, compressor, and bypass lines where stable throttling and controlled flow are required.
Confirm Key Parameters
Verify temperature, pressure class, valve size, operating frequency, actuation, insulation, shut-off speed, and certification requirements.

Send Us Your P&IDCryogenic Valve Design for Reliable Operation Down to -196°C
Reliability at cryogenic temperature comes from four design fundamentals, standard on every Gowin cryogenic valve.
Extended Bonnet
Keeps packing away from the cold zone to reduce freezing, leakage, and stem seizure in direct LNG service.
Cryogenic Sealing
Lip seal or hard-faced sealing surfaces maintain shut-off reliability, while low-emission packing supports ISO 15848 leakage control.
Pressure Relief
Self-relieving or upstream relief designs prevent cavity overpressure caused by LNG vaporization during temperature rise.
Stem & Safety
Blow-out-proof stems, anti-static features, fire-safe sealing, and optional fail-safe actuation improve critical isolation safety.

Material and actuation selection is matched to environment — marine, arctic, or corrosive/sour service — not applied as a single default.
Marine & High-Salt
Duplex F51, Super Duplex F53, Inconel, and Monel, with corrosion-resistant coatings. Suits LNG carriers, offshore facilities, and marine terminals; consider BV Marine & Offshore and fire-safe requirements.
Extremely Cold Regions
LCB and LC3 low-temperature carbon steel for gate/globe valves; CF8, CF8M, CF3, CF3M for ball valves. Low-temperature impact testing verifies toughness; heat numbers stay fully traceable.
Corrosive / Sour Service
Duplex, Super Duplex, and Hastelloy options, compliant with NACE MR0175 / ISO 15156. HIC and SSC testing available when required by the project spec.
Actuation Options
Manual, pneumatic, electric, or gas-over-oil / hydraulic. Fail-Open/Fail-Close and spring-return pneumatic actuators for ESD; standardized interfaces support future automation upgrades.
Cryogenic Valve Testing, Standards and Quality Control
Every cryogenic valve is verified in-house before it reaches a customs port, backed by full material traceability and optional third-party witnessing.
Cryogenic & Leakage Testing
In-house cryogenic testing capability covers service conditions down to -196°C, for valves up to NPS 24. Seat sealing, stem sealing, and overall valve performance are verified alongside body strength (1.5× rated pressure) and seat leakage (1.1× rated pressure) tests.
Material & NDE Testing
Chemical composition analysis, mechanical property testing, low-temperature impact testing, hardness testing, metallographic analysis, RT/UT/MT/PT, and HIC/SSC testing — all traceable from raw material to finished valve.
Applicable Standards & Certifications
Third-Party Inspection
Witnessing can be arranged with SGS, BV, Lloyd's Register, Intertek, or TÜV for material inspection, dimensional inspection, pressure testing, NDE, and cryogenic testing according to the project ITP.

Contact Our Engineering TeamCryogenic Valves for LNG — Frequently Asked Questions
Which cryogenic valve is suitable for LNG storage tanks?
Selection depends on the valve location and duty. A cryogenic ball valve is preferred for rapid isolation, a gate valve suits large-bore tank-bottom lines, and a cryogenic globe valve is recommended for BOG and flow-control duties.
What is the difference between a cryogenic ball valve, gate valve, and cryogenic globe valve?
Cryogenic ball valves are designed for rapid shut-off and frequent operation. Gate valves suit large-bore, low-resistance isolation, while cryogenic globe valves are intended for BOG and process flow regulation.
Why does a cryogenic valve require an extended bonnet?
An extended bonnet keeps the packing area away from the extremely cold process zone, reducing packing freezing, loss of elasticity, stem seizure, and external leakage.
How does a cryogenic valve prevent abnormal cavity overpressure?
Ball valves use a cavity self-relieving design, while gate and globe valves use an upstream pressure-relief arrangement to manage pressure caused by trapped LNG vaporization.
How are cryogenic valves tested at -196°C?
Seat sealing, stem sealing, and overall valve performance are verified under cryogenic conditions, together with body strength, seat leakage, gas leakage, and material impact testing.
Which materials are suitable for marine LNG cryogenic valve applications?
Depending on salt exposure, seawater corrosion, and process media, Duplex F51, Super Duplex F53, Inconel, and Monel can be selected with appropriate corrosion-resistant coatings.
Can a cryogenic valve manufacturer customize valves according to our P&ID or datasheet?
Yes. Our engineering team reviews your P&ID, datasheet, media, temperature, pressure, and size to determine the valve type, material, sealing system, pressure class, and actuation.
What certifications and technical documents can Gowin provide for cryogenic valve projects?
Depending on project requirements, we can provide MTRs, pressure test certificates, cryogenic test reports, NDE reports, dimensional inspection reports, as-built drawings, IOM manuals, and applicable API, ISO, CE/PED, BV, and related certification documents.
