Frequently Asked Questions
  • Q
    What safety features does this cryogenic ball valve include?

    The valve is designed with anti-static protection, an anti-blowout stem, and a fire-safe construction to ensure safe and reliable operation in demanding cryogenic environments.

  • Q
    What is the advantage of a top entry construction?

    Top entry construction allows maintenance and inspection to be performed directly in-line, meaning the valve does not need to be removed from the pipeline — reducing downtime and labor costs significantly.

  • Q
    How does the extended stem design protect valve performance in cryogenic applications?

    The extended stem keeps the packing gland away from the extreme cold of the cryogenic medium, preventing packing material degradation and ensuring long-term sealing reliability even at very low temperatures.

  • Q
    What types of actuators are compatible with the ISO 5211 mounting pad?

    The ISO 5211 standard mounting pad is compatible with a wide range of actuators, including manual handwheels and levers, pneumatic actuators, electric actuators, and hydraulic actuators — offering maximum flexibility for your application.

  • Q
    Can the valve materials be customized for specific media or operating conditions?

    Yes. The valve body, ball, seat, and stem materials can all be tailored to meet specific process requirements, including compatibility with different media, pressure ratings, and temperature ranges.

  • Q
    How are cryogenic ball valves tested before delivery?

    Every cryogenic ball valve undergoes rigorous in-house cryogenic testing before shipment. This includes pressure testing and leak testing at cryogenic temperatures to verify bubble-tight shut-off and confirm that all sealing components perform reliably under actual operating conditions.
