The purpose of storage and maintenance is to prevent valve damage or reduce quality during storage. In fact, improper storage is one of the important reasons for valve damage.
Valve storage should be well-organized, with small valves placed on shelves and large valves neatly placed on the warehouse floor. They should not be piled up randomly and should not allow the flange connection surface to directly contact the ground. This is not only for aesthetics, but more importantly, to protect the valve from damage. Due to improper storage or handling, the handwheel may be broken, the valve stem may become crooked, and the fixing nut between the handwheel and the valve stem may become loose or lost. These unnecessary losses should be avoided.
For valves that are temporarily not in use in the short term, asbestos packing should be removed to avoid electrochemical corrosion and damage to the valve stem.
The inlet and outlet of the valve should be sealed with wax paper or plastic sheets to prevent dirt from entering and affecting the valve.
Valves that can rust in the atmosphere should be coated with anti rust oil for protection and to prevent rusting.
Valves placed outdoors must be covered with rainproof and dustproof items such as felt or tarpaulin. The warehouse storing valves should be kept clean and dry.
