2025 10 Leading Plug Valve Manufacturers in China - Blog

Introduction to Plug Valve

A plug valve is a type of quarter - turn valve that uses a tapered or cylindrical plug to control the flow of fluid through a pipeline. The plug has one or more passages that can be aligned with the inlet and outlet ports of the valve body to permit flow or turned perpendicular to block the flow. Plug valves are known for their simple design, quick operation, and ability to provide a tight shut - off. They are widely used in various industries such as oil and gas, chemical, water treatment, and power generation due to their reliability and versatility in different media, including liquids, gases, and slurries.
