How to properly store fluorine-lined valves?

The storage of fluorine-lined valves should first be done in a suitable environment. The room should be kept dry and clean, and cleaned regularly. At the same time, the valves should not be exposed to direct sunlight for a long time to avoid aging and deformation.
In addition, the sealing surfaces of the fluorine plastic flanges at both ends should have protective covers, and the sealing surfaces should not be scratched or subjected to pressure.
When entering the warehouse, the name, model, specification, number, quantity and date of entry of the fluorine-lined valves should be recorded to prevent confusion.
