Topper provides cryogenic ball valves that have the following features:
1. A cryogenic ball valve is a kind of valve that is mainly for ethylene, liquefied natural gas and other chemical devices. Cryogenic ball valves are mainly divided into cryogenic floating ball valves and cryogenic standing ball valves.
2. Long-necked structure is not usually applied for temperature above -50℃, and applied for temperature below -50℃. It aims to protect the stuffing box, locate stuffing box far away from low temperature, and guarantee sealing effect of the stuffin. Cold insulation materials can also be used to prevent loss of cold energy.
