Plug Valves: The Precision Flow Control Star in Industrial Production
27 Feb, 2026
Recently, industry study examining the compatibility between valve shape and operate condition were formal released. Plug valve have become a core choice for precision flow control in industrial production. Their unique conical valve core and adaptability to various environments have contributed to this. Related material and manufacturing process improvements, maintenance techniques, have attract widespread attention in the industry.
The research results clearly demonstrate that the conical valve core in plug valves is crucial for achieving precise control: in most cases, the flow rate changes almost linearly with the valve stem stroke. In other words, the greater the valve stem stroke, the greater the flow rate. This maximizes the stability of process parameters. This characteristic gives plug valves a unique advantage in high-precision applications, such as feed regulation in chemical reactors, flow ratio control in water treatment processes, and precise fluid control in various instruments. The inverted conical valve core is characterized by rapid opening and closing, while the plug valve offers precise regulation. Together, they fill a gap in the field of precision fluid management.
In addition, the research team developed a practical solution for maintaining plug valves. Sticking can occur when the valve is permanently open, and it can also stick when operating in the closed position. This solution addresses this problem. How does it work? The key is that lubricant can be supplemented using a dedicated grease injection device without stopping the equipment, ensure continuous and stable valve operation. This maintenance feature further enhance the suitability of plug valves for continuous production environment.
Industry experts point out that plug valves have many advantages, such as their conical valve core design, compatibility with different materials, and convenient maintenance. Therefore, plug valves have become the best product in the field of precision flow control. As industrial manufacture processes become more and more sophisticated, and laboratory equipment become more and more advanced, the application scenarios for plug valve will continue to expand. In different application scenarios, their technological advancement and adaptability will become important directions for industry innovation.
