Forged Steel Cryogenic Globe Valves by EATHU: Reliable Solutions for Low-Temperature Applications

June 20, 2025

 Engineered for Cryogenic Performance


EATHU's cryogenic globe valves are purpose-built for systems handling liquefied gases such as LNG, liquid oxygen, nitrogen, and other cryogenic media. These valves are widely used in:

  • Cryogenic storage tanks and pipelines

  • LNG transportation systems

  • Petrochemical and chemical plants

  • Aerospace and industrial gas facilities

Unlike conventional globe valves, which typically operate from -40°C to +500°C, EATHU cryogenic valves are optimized for ultra-low temperature operation between -196°C and -150°C.

EATHU cryogenic globe valves

 Key Features


  • Flexible Operation: Smooth on/off control even at extreme temperatures

  • Reliable Sealing: Engineered for zero-leakage performance

  • Low Heat Transfer Design: Prevents internal pressure build-up caused by vaporization

  • Extended Bonnet Structure: Keeps the packing area close to ambient temperature to maintain seal integrity

  • Fire-Safe & Explosion-Proof Components: For added safety in hazardous environments


 Cryogenic-Specific Design Advantages


Cryogenic applications require more than just cold tolerance. EATHU's valve design ensures:

  • Continuous long-term performance under low-temperature and low-pressure conditions

  • Prevention of frost damage and thermal shock

  • Minimization of external heat ingress to preserve media stability

  • Surface-treated valve stems to prevent galling and leakage


 Premium Material Selection


The right materials are essential for safe and efficient cryogenic valve performance. EATHU uses carefully selected alloys and treatments for all major components:


Main Body:

  • Austenitic stainless steel for -100°C and below

  • Ferritic steel for -20°C to -100°C

  • Aluminum & copper alloys for small-diameter, low-pressure applications


Stem & Bolts:

  • Nickel-based alloys or Cr-Mo steel with special surface treatments (hard chrome plating, nitriding)

  • Mo or Ni nuts with molybdenum disulfide coating to prevent thread seizure


Seals & Gaskets:

  • Optimized materials with low shrinkage at cryogenic temperatures

  • Long-neck bonnet design to keep the sealing elements away from extreme cold
