Section 1 Maintenance of the valve during transportation 

The valve hand wheel is damaged, the valve stem is bent, the bracket is broken, and the flange sealing surface is bumped and damaged, especially the damage of the gray cast iron valve. A considerable part of it occurs in the valve transportation process. The reason for the above-mentioned damage is mainly caused by the poor understanding of the basic common sense of the valve by the transportation personnel and the brutal loading and unloading operations.
