Cryogenic Valve
As a leading Cryogenic Valve Supplier in Dubai, UAE Valves provides engineered solutions that withstand temperatures down to –196°C for LNG, petrochemical, and industrial gas applications. Built to international standards, our cryogenic valves deliver safe, leak-tight, and reliable performance in processes where precision and safety are non-negotiable.
How Cryogenic Valves Work
Cryogenic valves are specifically designed to handle fluids at extremely low temperatures. They feature extended bonnets that keep stem packing insulated from cryogenic liquids, preventing frost damage and ensuring smooth operation. Carefully selected trims, seals, and body materials minimize contraction stress and guarantee tight shutoff even under demanding conditions.
Cryogenic Valve Benefits
- Ensures safe, leak-tight service at cryogenic temperatures.
- Extended bonnet design prevents stem freezing.
- Maintains reliable sealing under thermal contraction.
- Smooth actuation with low torque requirement.
- Qualified and tested to international cryogenic standards.
