Marine valve

Valves are produced with the production of fluid lines. Humans have used valves for nearly 4000 years. In ancient China, cork valves were used in bamboo pipelines when brine was sucked from salt wells to make salt. China's valve market price is relatively stable. Although it rises or falls slightly every year, the range is very small. The market prospect of the valve industry is still widely optimistic. 

It is worth noting that, at present, the competition in the valve industry is still not standardized, or has an impact on the development of the valve industry. The main problems include: 1. Some operators purchase valves without factory name and address, print famous brand names and certificates of well-known manufacturers, and cause serious damage to the reputation of qualified valve enterprises; 2. Refurbishment of valves. Some operators sold the old valves for the second time after repainting them, bringing serious potential safety hazards to the engineering quality. At present, there are many problems in the auto-control valve market. First, some operators are cheap and buy valves with no factory or name, bearing the nameplate and certificate of approval of famous manufacturers, causing great damage to the reputation of regular valve enterprises.
