F316 Forged API Cryogenic Ball Valve
Cryogenic ball valve is suitable for service of working temperature down to -196ºC, such as LNG, LPG, and air separation industry. The cryogenic ball valves are produced by the most advanced technology. It is designed with LIP SEAL which can keep valves with excellent sealing performance in ultra-low temperature.
Main features of the cryogenic ball valve.
- Bonnet extended
- Low fugitive emission control
- Lip seal
- Cavity pressure self relief
- adopt import seat material of stable low temperature performance
- The seat and pressure relief structure can be adapt varies working condition
- Top entry structure is convenience to on-line maintenance

The applications of cryogenic ball valves.
Cryogenic ball valves have a wide range of applications, mainly including liquid transportation systems, liquefied gas storage tank systems, air conditioning and refrigeration equipment, and low-temperature water treatment systems. The use of cryogenic ball valves can ensure that the system has good sealing performance and corrosion resistance, and guarantee the safety and long-term stable operation of the system.
What is a cryogenic ball valve?
A cryogenic ball valve is a type of valve designed to operate in extremely low-temperature environments. It controls the flow of cryogenic fluids (such as liquefied gases) with good sealing and corrosion resistance, ensuring system safety and stable operation.
How to keep a ball valve from freezing?
Insulate the valve to prevent cold penetration. Use trace heating if needed. Ensure proper drainage to avoid trapped fluid. Choose cold-resistant materials for the valve.
