Katup Bola Kriogenik dengan Masuk Samping untuk Penggunaan LNG
Katup bola kriogenik WDL tipe masuk samping memberikan penutupan yang andal untuk LNG, nitrogen cair, oksigen cair, dan media bersuhu rendah lainnya hingga -196°C.
Deskripsi
control of low-temperature fluids in demanding industrial systems. They are suitable for
LNG, liquid nitrogen, liquid oxygen, liquid argon and other cryogenic media where
dependable sealing and material toughness are essential.
The valve uses an extended stem design to keep the packing area away from the cold zone,
helping reduce frost formation and protecting the stem sealing system. Low-temperature
materials, carefully selected seat options and a robust side entry body construction
support reliable performance in cryogenic pipeline service.
Fitur Utama
- Suitable for cryogenic service down to -196°C.
- Extended bonnet or extended stem design to reduce frost at the packing area.
- Side entry two-piece or three-piece body construction.
- Low-temperature stainless steel materials with good toughness.
- Reliable soft-seated sealing for low-leakage shut-off service.
- Metal-seated options available for specific pressure and temperature requirements.
- Elastic seat compensation helps maintain sealing performance during temperature changes.
- Manual, pneumatic and electric actuation options available.
- Fire-safe and anti-static designs available according to project requirements.
- Available in customized materials, sizes, pressure ratings and end connections.

Cryogenic Design Advantages
At very low temperatures, ordinary materials may lose toughness and become vulnerable to
brittle fracture. WDL Valve selects cryogenic-compatible stainless steel materials and
applies controlled manufacturing and testing procedures to support safe operation in
low-temperature conditions.
The extended stem configuration separates the stem packing from the cold fluid area.
This design helps limit ice accumulation around the operating mechanism and supports
smoother valve operation. Seat designs can also be selected to compensate for material
contraction caused by temperature changes.
