WENG'S HUAJIAN CO.,LTD addition, according to the statistics of the photo gate, the annual turnover of the valve market in my country is as high as 50 billion yuan, and the market of more than 10 billion yuan is occupied by foreign valve companies. At present, my country's valve industry still has some indelible problems. For example, my country's valve companies mainly follow low-level, small-scale, family-owned enterprises. In terms of products, due to repeated investment and insufficient technology introduction, the guided products of my country's valve companies are still low-volume and large-scale products. At present, all kinds of valves produced by Chinese enterprises are full of false truths such as non-extinguishable external leakage, internal leakage, low external leakage, short life, poor operation, and failure of electric valve installation and pneumatic tee joint pipe tube pipe fittings installation.
