Cryogenic globe valve N310

Description

Material (Forged Valve):

• Body, Bonnet, and Disc: Forged Carbon Steel, Low Temperature Carbon Steel, or Stainless Steel (e.g., 316L, 316LN)
• Stem: 17-4PH Stainless Steel or other low-temperature compatible materials
• Packing: PTFE or other low-temperature compatible packing
• Gasket: Metal-to-metal or soft gasket suitable for cryogenic temperatures

Material (Casted Valve):

• Body, Bonnet, and Disc: Cast Carbon Steel, Low Temperature Carbon Steel, or Cast Stainless Steel (e.g., CF8M, CF8)
• Stem: 17-4PH Stainless Steel or other low-temperature compatible materials
• Packing: PTFE or other low-temperature compatible packing
• Gasket: Metal-to-metal or soft gasket suitable for cryogenic temperatures

Performance:

• Temperature Range: -196°C to 120°C (or lower, depending on specific design)
• Pressure Rating: Class 150, 300, 600, 900, or 1500 (or higher, depending on specific design)
• Leakage Class: Zero leakage or low leakage, depending on the specific application
• Cycle Life: High cycle life, suitable for frequent operation

Considerations:

• Low-Temperature Lubrication: Special low-temperature lubricants may be required for valve operation
• Thermal Shock Resistance: The valve is designed to resist thermal shock
• Corrosion Resistance: The valve is resistant to corrosion from the cryogenic fluid and any impurities it may contain.
• Cryogenic Fluid Compatibility: The valve materials and lubricants must be compatible with the specific cryogenic fluid being used.
