From LNG to liquid hydrogen, air separation to aerospace applications, these "cryogenic-resistant workhorse valves" deliver reliable performance under extreme cryogenic conditions ranging from -162°C down to -269°C.

🌡️ Five Core Medium Valves (Full Coverage of Extreme Cryogenic Temperatures)

▫️ LNG Valves | Rated for -162°C

Core equipment for natural gas liquefaction, dedicated to receiving terminals and storage tanks; featuring zero-leakage performance and high-pressure resistance.

▫️ Liquid Nitrogen (LN₂) Valves | Rated for -196°C

Primary solution for industrial cooling and food quick-freezing processes; anti-ice-block design with superior resistance to low-temperature thermal shock.

▫️ Liquid Oxygen (LOX) Valves | Rated for -183°C

Mandatory components for air separation units and aerospace oxidizer supply systems; static-discharge prevention, flame-retardant sealing for maximum operational safety.

▫️ Liquid Hydrogen (LH₂) Valves | Rated for -253°C

Critical hardware for commercial hydrogen energy deployment; engineered with hydrogen embrittlement mitigation and ultra-high tightness sealing, representing top-tier industry performance.

▫️ Liquid Helium (LHe) Valves | Rated for -269°C

Ultimate cryogenic solution for superconductivity equipment and scientific research; capable of stable long-term micro-flow regulation under superfluid helium conditions.

⚙️ Four Mainstream Valve Types (Full-Scenario Compatibility)

Ball Valves for LOX, LN₂ and LH₂

Rapid open/close actuation plus superior sealing performance; the preferred valve type for LNG plants and air separation facilities.

Butterfly Valves for LHe, LN₂, LOX and LH₂

Compact, lightweight footprint to save installation space, optimized for large-flow pipeline systems.

Control Valves for LN₂, LHe, LH₂ and LOX

Precise flow modulation capability, essential for laboratory research and fine chemical processing.

Globe Valves & Gate Valves

Globe valves compatible with LN₂, LHe, LH₂, LOX media; LN₂ service gate valves; deliver dependable shutoff function as safety isolation guardians for process pipelines.
