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