Application Description
The medium is a hydrogen/methane mixture: operating temperature −162 ℃, design temperature −175℃, design pressure 4.5 MPa. It is flammable and explosive, highly volatile, with wide temperature and pressure fluctuations.
Application Focus
- Low medium temperature — risk of cold cracking and cold embrittlement;
- Flammable and explosive — external leakage must comply with TA-Luft;
- Highly volatile, with wide temperature and pressure swings — pressure relief capability required;
- Tight shutoff required: metal-seated Class VI or API 598;
- Fire-safe and anti-static;
- High control accuracy required.
Solution Overview
The H100 cryogenic control valve serves continuous process control, the VB100 cryogenic butterfly valve suits large-diameter, high-capacity isolation, and the R100 top-entry cryogenic ball valve delivers reliable isolation from small to large diameters.
- Three valve types — cryogenic control valves, butterfly valves and ball valves — allow flexible selection to match piping and functional requirements across a range of diameters and pressure ratings.
- All valve types use an extended-bonnet plus drip-plate cryogenic design that isolates the packing box from the cold medium and prevents frost and ice build-up; bodies and trim receive deep cryogenic treatment to eliminate deformation and stress risks from low-temperature phase change.
- Sealing meets international leakage classes and is fitted with an ISO 15848 fugitive-emission packing system; ball valves provide bidirectional sealing plus DBB/DIB function for safe cavity relief.
- Ball valves integrate anti-static and fire-safe features; flanged, welded and other connection options suit different tank farm and storage/transportation layouts.
Customer Value
- Mitigates failure risks from cold embrittlement and packing frost/ice, controls leakage and improves plant safety.
- The valve-type combination handles fluctuating temperature and pressure, reducing unplanned downtime and supporting stable process operation.
- Aligned with TA-Luft, ISO 15848, API 598 and other international standards, supporting compliance review on overseas projects.
- Top-entry design simplifies maintenance and multiple connection options suit site installation, cutting service work and product loss.
- An integrated product portfolio simplifies selection and interfacing, streamlining procurement and execution.
