Valve custody, should be in perfect order, small valve on the shelf, large valve can be arranged neatly on the floor of the warehouse, can not be disorderly pile pile pile, do not let flange connection surface contact the ground. This is not only for aesthetics, but mainly to protect the valve from damage.

 

Unnecessary losses due to improper storage and handling, broken handwheel, bent stem, loose and missing fixed nut between handwheel and stem, etc., should be avoided.

 

For valves that are not in use for a short time, remove the asbestos packing to avoid electrochemical corrosion and damage to the stem. The valve that just entered the warehouse should be checked, such as in the process of transportation into rain or dirt, wipe clean, and then storage.

Valve inlet and outlet should be sealed with wax paper or plastic sheet to prevent dirty things. Can rust in the atmosphere of the valve processing surface to coating rustproof oil, to protect.

Outdoor valves must be covered with tarpaulin or tarpaulin to prevent rain and dust. Keep valve storage area clean and dry.
