Reliable Cryogenic Globe Valve
The Cryogenic Globe Valve is specially designed to control the flow of extremely cold gases and liquids, like those used in liquefied natural gas (LNG) applications. This valve has a unique extended stem that keeps the handle warm and prevents freezing, allowing easy control even at very low temperatures.
Inside, a disc moves up and down to regulate flow, making it perfect for precise adjustments. Built to withstand freezing conditions without damage, the Cryogenic Globe Valve is reliable and safe for use in industries where extremely cold materials are handled regularly.
Control de calidad
The PMI test checks the Cryogenic Globe Valve’s material composition to confirm it matches the required specifications. This helps maintain product reliability in cold environments.
Prueba PMI
During the sealing test, the Cryogenic Globe Valve is tested for leaks, verifying it holds pressure effectively under low-temperature conditions.
Prueba de estanquidad
The low emission test measures how much gas escapes from the Cryogenic Globe Valve. It helps maintain safe environmental standards during its operation.
Prueba de bajas emisiones
In the impact test, the Cryogenic Globe Valve is hit with force to check its durability. This proves its strength under extreme cold conditions.
Prueba de impacto
The dimension inspection verifies if the Cryogenic Globe Valve’s measurements are accurate. It confirms the valve fits perfectly with other system components.
Inspección dimensional
The painting thickness test checks if the Cryogenic Globe Valve’s protective coating is applied properly. This prevents corrosion and prolongs the valve’s life.
Prueba de espesor de pintura
The PT, or penetrant test, detects tiny surface cracks in the Cryogenic Globe Valve. This verifies there are no weaknesses that might lead to leaks.
PT
The material inspection examines the raw materials used in the Cryogenic Globe Valve. It confirms they are suitable for extreme cold and high-pressure environments.

Universal Characteristics
Body Material Selection
Brittleness occurs in common steel at low temperatures, so the body material must meet the requirements for the working conditions.
- Temperatura: -110°C to -196°C
- Recommended Materials: CF3, CF3M, CF8M, CF8, F316L, F304L, F316, F304, Dual Certified, etc. These materials are suitable for cryogenic service.
Stem Extension Structure (Not Applicable to Check Valve)
- Extending the valve bonnet keeps the packing at room temperature, supporting effective sealing performance.
- By default, extending the height of the valve bonnet meets the requirements of BS6364 and SPE 77/200, but it can also be customized based on customer needs.
- The lengthened valve bonnet facilitates easier winding of the insulation layer, helping to prevent cold energy loss.
End Connection
- BW
- RF
- RTJ
- etc.
Prevention of overpressure in the valve cavity
To avoid the risk of overpressure, consider the following designs:
- Self-relief seat
- Drilling holes in the ball
- Gate (upstream)
Fire-safe, Anti-static
NTVAL meets the requirements for fire and anti-static design. Corresponding qualification certificates are available.
Low Emission
All cryogenic valves are designed for low emissions and meet ISO 15848 and SHELL 77/312 requirements. Corresponding qualification certificates are available.
Note
- MDMT is as per ASME B31.3.
- Design standards reference SPE 77/200, BS 6364, ASME B16.34, and relevant API/ASME/ISO standards.
