Cryogenic Check Valve is specifically designed to prevent reverse flow in piping systems handling extremely low-temperature fluids, such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), and other cryogenic gases. These valves ensure reliable backflow prevention in cryogenic applications, maintaining system integrity and operational safety under sub-zero conditions. The valves are engineered with an extended bonnet to insulate the valve stem and reduce thermal losses, ensuring smooth, uninterrupted operation even at temperatures as low as -196°C.
Cryogenic check valves are widely used in industries such as oil & gas, petrochemical, and chemical processing, where the control of cryogenic fluids is critical. The valve operates automatically, allowing flow in one direction and closing to prevent reverse flow when the fluid changes direction.
Key Features:
- Extended Bonnet Design: Insulates the valve stem from low temperatures, ensuring smooth operation in cryogenic conditions.
- Automatic Backflow Prevention: The valve closes automatically when the flow reverses, preventing damage to equipment and ensuring system safety.
- Durable Construction: Built from high-quality materials to withstand both low temperatures and high pressures.
- Leak-Proof Sealing: Ensures zero leakage, maintaining the integrity of the cryogenic fluid system.
