Our Cryo extension bonnet is specially designed to reduce heat exchange between the fluid and the environment and to keep the packing chamber temperature to a maximum. The Cryo bonnet adds dead space in which boiled-off vapors collect, further insulating the top of the valve from the fluid.
Valvero offers two types of extension bonnets (short and long) which are available to better locate the gland packing closer to the ambient temperature zone. This will protect it from freeze damage caused by low-temperature fluid.

- An extended bonnet to the cryogenic ball valve can make the packing gland in the valve and the actuator further away from the cold process so the valve can open and close properly, protecting it from freeze damage caused by low-temperature fluid.
- Low operating torque for smoother operations.
- Excellent seat and seal design minimizes leakage.
- Fire-safe design.
- Rigid body construction minimizes thermal shrinkage.
- By adopting different materials, the cryogenic ball valve is applicable to different working temperatures and mediums. The minimum temperature for the ball valve is -196ÂşC.Â
- Cryogenic ball valves are used in applications that require handling fluids at very low temperatures, such as in the aerospace and petrochemical industries
- Liquefied natural gas (LNG)
- Liquefied petroleum gas (LPG)
- Liquefied oxygen
- Liquefied hydrogen
- Air separation industry
