There are many domestic product developments, and the start time is relatively late. In the process of product research and development, the technical strength of the product is in a less stable stage. There are some products that differ from those produced by internationally renowned manufacturers in terms of quality. During the production and processing of domestic marine valves, has the technical level already reached the international advanced level? When the product is used, can it be guaranteed that it can meet the needs of the domestic shipbuilding industry during the use of the product?
