Frequently Asked Questions
The valve incorporates an anti-static design, an anti-blowout stem, and a fire-safe construction. These features collectively ensure safe, reliable operation even in demanding cryogenic and high-risk environments.
Yes. The top entry construction allows for complete in-line maintenance and inspection without disconnecting the valve from the pipeline, significantly reducing downtime and maintenance costs.
The extended stem keeps the packing assembly away from the extremely cold medium, preventing thermal degradation and ensuring long-term sealing reliability in cryogenic applications such as LNG, liquid nitrogen, or liquid oxygen service.
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 — providing maximum flexibility for automated or manual control systems.
Absolutely. The body, ball, seat, and stem materials can all be tailored to meet specific process requirements, including compatibility with corrosive media or extreme temperature ranges. Custom configurations are available upon request.
Every valve undergoes rigorous in-house cryogenic testing prior to shipment. This testing verifies bubble-tight shut-off performance, structural integrity, and sealing reliability under actual cryogenic conditions, ensuring quality and safety compliance before the valve reaches the customer.
