| Model Number | DJ61F DJ61W | Place of Origin | CHINA |
Our DJ61 Series Long-Stem Cryogenic Globe Valves are engineered for the safe and efficient handling of liquefied gases down to -196°C (-321°F). The defining feature is our purposeful extended bonnet and stem design. This crucial Long-Stem architecture isolates the extreme cold of the process fluid from the valve packing and operating mechanism, preventing external icing, ensuring smooth operation, and guaranteeing reliable sealing in ultra-cold environments.
The series offers two primary sealing solutions to meet diverse operational demands:
| Feature | DJ61F (Soft-Seated) | DJ61W (Hard-Seated) |
|---|---|---|
| Seat Type | PTFE (Polytetrafluoroethylene) Soft Seal | Metal-to-Metal Hard Seal |
| Key Advantage | Bubble-tight sealing, achieving near-zero leakage. Low operating torque. | Excellent abrasion and erosion resistance. Long service life, wider temperature adaptability. |
| Temp. Range | -196°C to +80°C | -196°C to +200°C |
| Typical Media | Clean cryogenic liquids: LNG, Liquid Oxygen, Liquid Nitrogen, Liquid Argon. | Cryogenic gases with potential particles, refrigeration systems, pipelines requiring higher wear resistance. |
| Design Std. | BS6364, GB/T 24925, API 602 | BS6364, GB/T 24925, API 602 |
Superior Cryogenic Performance
All parts exposed to cryogenic media undergo strict deep-cryogenic treatment to stabilize the material structure and prevent thermal contraction.
Materials like ASTM A351 CF8/CF8M (304/316 SS) or Duplex Steel are used, validated by -196°C Charpy Impact Tests for guaranteed low-temperature toughness.
Reliable Long-Stem Design & Sealing
The extended stem design is the hallmark of this Long-Stem Cryogenic Globe Valve, creating a thermal barrier to protect the packing box.
Features an anti-blowout stem design and is packed with cryogenic-grade materials (e.g., flexible graphite) for operational safety and long-term sealing integrity.
Rigorous Quality Assurance
Every valve is 100% tested with Helium Mass Spectrometry Leak Detection for performance far exceeding standard hydrostatic/pneumatic tests.
Our comprehensive quality system holds ISO 9001 and CE certifications, with SIL compliance support available.
Size Range: DN15 ~ DN200 (½" ~ 8")
Pressure Rating: PN16 ~ PN100 (Class 150 ~ 600)
End Connections: Butt-weld, Socket-weld, or Flanged
Actuation: Manual, Pneumatic, or Electric Actuators
