Cryogenic Gate Valve
Cryogenic gate valve for service down to -196°C with extended bonnet, suitable for LNG and LPG storage/transport.
Inquire NowProduct Overview
The cryogenic gate valve is designed for full-bore isolation in LNG, LPG, and other low-temperature service. Its extended bonnet keeps the packing area above the chilled zone, and the rigid wedge maintains tight shutoff across thermal cycles.
The valve is impact-tested per BS 6364 / EN 1626 and meets the requirements for cryogenic service as used in LNG carriers, receiving terminals, and storage tanks.
Key Features
- -196°C Service: Proven in LNG, LPG, LH₂, LIN applications
- Extended Bonnet: Long neck isolates packing from chilled zone
- Full-Bore Design: Matches pipe ID for pigging and full flow
- Cryogenic-Tested: Every valve impact-tested at -196°C
- Multiple Seat Options: Metal or PTFE seat depending on service
Technical Highlights
Typical Applications
LNG receiving terminals, LNG carriers, LPG storage tanks, air separation plants, ethylene transport.
