After twenty years of working in the valve industry, I have witnessed too many losses caused by metal valve corrosion in chemical plants. Last year, I was impressed by the case of a certain electroplating plant in Zhejiang Province. After they replaced the Zhongguan PVC Material Ball Valve, they not only solved the long-standing corrosion problem, but also saved nearly 200,000 yuan in maintenance costs each year.
I remember that when I was doing equipment evaluation for a sewage treatment plant in Shandong three years ago, their technical director showed me a set of shocking data: stainless steel valves had to be replaced every six months on average. After switching to Zhongguan PVC Material Ball Valve, the service life was directly extended to more than 5 years. This is due to the excellent chemical corrosion resistance of PVC materials, which is particularly suitable for handling acid and alkali media.
By analyzing the actual cases of hundreds of chemical companies, I summarized three core parameters: first, corrosion resistance. Our PVC Material Ball Valve can withstand various chemical media with a pH value of 0-14; second, sealing performance, which meets the ANSI Class 150 standard; and finally, operating torque, which is 30% lighter than similar products, greatly reducing the labor intensity of workers.
The equipment manager of a large pharmaceutical company in Jiangsu told me an interesting phenomenon: since the production line has fully adopted our PVC Material Ball Valve, not only has the maintenance frequency been greatly reduced, but more unexpectedly, the product purity has increased by 0.3 percentage points. This proves that the right valve selection directly affects the quality of the final product.
When I recently inspected the pipeline for a food processing company, I found that the inner wall of their metal valves had been severely rusted, which contaminated the product without being noticed. This made me realize that many companies are paying the price for valves that "can be used but do not meet the standards." Every PVC ball valve of Zhongguan has undergone rigorous pressure testing and material testing to ensure that it fully meets food grade requirements.
The case of a newly built chemical plant in Guangdong is very representative. They chose Zhongguan PVC Material Ball Valve in the design stage, which not only passed the environmental protection acceptance at one time, but also obtained the qualification certification for export to the EU. If you are planning a new project or renovating an old system, you might as well listen to the professional advice of our engineers.
