Cryogenic Valves
Cryogenic Ball Valve
Extended-bonnet cryogenic ball valves engineered to handle ultra-low temperature gases like LNG, liquid nitrogen, oxygen, and hydrogen.
OVERVIEW
What Are Cryogenic Valves?
Cryogenic valves operate below -50°C down to -196°C. They feature an extended bonnet column (gas column) to keep stem packing close to ambient temperature, preventing freezing and leakage.
Key Features
- ✔️ Designed for Cryogenic Service - Reliable operation in ultra-low temperature applications
- ✔️ Bubble-Tight Shut-Off - Quarter-turn ball design ensures secure, leak-free isolation
- ✔️ Extended Bonnet Design - Reduces heat transfer and protects stem sealing components
- ✔️ Low Torque Operation - Smooth quarter-turn actuation for fast and efficient valve control
- ✔️ Ideal for LNG & Industrial Gases - Suitable for LNG, LOX, LIN, LAR, LPG, and other cryogenic media
