Cryogenic Emergency Shut-Off Valves & Safety Valves for LNG and Cryogenic Applications

At Guard Europe BV, we understand that cryogenic applications such as LNG (Liquefied Natural Gas) and LC₂H₄ impose exceptional demands on safety and reliability. That’s why we offer a comprehensive range of cryogenic emergency shut-off valves and safety valves, specifically engineered to operate under extreme temperatures ranging from -196°C to +80°C, and in harsh conditions such as transportation and storage.

Cryogenic Emergency Shut-Off Valve – Automatic Protection at Elevated Temperature

The cryogenic emergency shut-off valve is an essential safety device for cryogenic storage tanks and tank trucks. When the ambient temperature rises above 70 ± 5°C, the valve closes automatically. This immediately cuts off the medium and keeps the installation protected.

Key features:

• Automatic closure at elevated temperature

• Protects cryogenic tanks and tank trucks

• Suitable for LNG and LC₂H₄

• Medium flow direction: from the high- to the low-pressure side of the valve body
