Q: What are the key valve enterprises in China? Mainly in those areas?: Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
