After two decades in the valve industry, I've seen plants waste millions on oversized gate valves and high-maintenance ball valves when a simple Butterfly Valve would have done the job better. The ZHONGGUAN VALVE team has helped hundreds of facilities cut costs by switching to our engineered Butterfly Valves - but what exactly makes them the smart choice for flow control?

​In the world of valves, two key valves with "ball" in their names—ball valves and float valves—are often confused. Although both have the "ball" in their names, their functions, applications, and operating principles are completely different. Choosing the wrong valve can lead to equipment failure or even safety accidents. As core components of fluid control systems, the differences between the two directly impact industrial safety and domestic water stability.

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.
