According to statistics from related departments, Wenzhou Valve Industry, which is a valve industry vane, obtained 8672 batches of export valve products from January to June. The export value was 269 million US dollars and the export value increased 42.33% year-on-year. After a sustained increase of nearly half a year, since June, Yongjia County's valve exports have experienced a two-month decline in growth. The continued weakness in foreign markets, the continuous growth of cost advantages, and the high-valued RMB exchange rate all put pressure on Yongjia small and medium-sized valve companies.
From the above data we can know that the current situation in the valve industry is not optimistic, a lot of valve companies affected by weak domestic and foreign markets, the industry has a sharp decline in domestic and foreign orders, production tasks are clearly insufficient, sustained high growth for many years are falling, some Due to the sluggish production and sales of enterprises, there have been some problems in the turnover of funds. The development of the industry and enterprises have encountered difficulties in varying degrees. It is expected that such a weak and difficult situation will be maintained until the second half of 2012 and will affect the first half of next year. This round of new difficulties has affected the valve industry and is also the most difficult period for the valve industry since the financial crisis.
It is understood that: Suzhou, a large-scale valve foreign trade enterprises, the order is obviously insufficient in the second half of 2012, the company general manager said that to maintain the level of exports last year is already good, may have to decline by 10% over the same period last year; Shanghai has a company CEO said “The valve business of companies is getting harder and harder, the production costs are high, and the costs are skyrocketing. The domestic and foreign markets are sluggish. Under such circumstances, the plans for companies to develop new products are also being put on hold for the time being. Minimize costs and keep capital running.
In the face of such unfavorable situation, our valve industry should actively respond to eliminate the current domestic and international economic downturn, to the negative impact of the valve industry, on the basis of stability, and actively respond to difficulties, to achieve a good completion of production and sales.
Driven by the four forces of industrialization, urbanization, reform and globalization, China's valve equipment manufacturing industry has broad prospects. The future high-end valve industry, localization, modernization, and digitalization will be the main direction for the future development of the valve industry.
IPC believes that the entire domestic valve equipment manufacturing industry is facing a "pain period" of industrial restructuring. In this regard, industry insiders call for, on the one hand, the government should strengthen the guidance and support for industrial transformation and upgrading, on the other hand, companies themselves must also strive to adjust the direction of industrial development, accelerate the pace of transformation and upgrading, to meet the needs of market development.
