Introduction
Cryogenic piping systems require valve components capable of operating reliably under extremely low-temperature conditions while maintaining correct flow direction and system integrity.
The Kyoei Valve Cryogenic Check Valve: SW Type Lift Check Valve / BB Type is a Japanese industrial check valve designed for cryogenic service involving liquefied gases.
Manufactured in Japan by Kyoei Valve Industry Co., Ltd., this valve is intended for demanding low-temperature applications where material selection, pressure class and operating temperature must be carefully evaluated.

Cryogenic Flow Protection
Lift check valves allow flow in the required direction while helping prevent reverse flow within a piping system.
For cryogenic applications, valve selection should consider more than nominal size alone.
Key parameters include:
Operating Temperature · Fluid · Material · Pressure Rating · Connection · Installation Conditions
The selected configuration should therefore be confirmed against the actual operating requirements of the system.
Typical Cryogenic Applications
The SW Type Lift Check Valve can be considered for systems handling cryogenic and low-temperature industrial media such as:
Liquid Nitrogen (LN₂)Liquid Oxygen (LOX)Liquid Argon (LAr)Carbon Dioxide
Potential applications include:
Industrial gas facilities
Cryogenic processing systems
Storage and transfer systems
Low-temperature process piping
Specialized industrial installations

For additional product information and Japan-side sourcing:
Sourcing Kyoei Valve Products from Japan
Nichiboku supports international industrial users requiring Kyoei Valve cryogenic valves, replacement equipment and related Japanese industrial components from Japan.
For quotation evaluation, provide whenever available:
Valve Type · Size · Pressure Class · Material · Operating Fluid · Operating Temperature · Quantity · Delivery Country
Where the valve is intended as a replacement for existing equipment, the original model, nameplate or technical drawing should also be reviewed before procurement.
Technical Selection Note
Cryogenic valve selection should be based on the complete application specification.
Similar valve size or appearance does not necessarily establish technical interchangeability.
Final technical suitability and approval remain with the responsible end user or engineering authority.
