The three-way flanged ball valve and the gate valve are both types of valves, but they differ in that the ball valve uses a ball that rotates on its central axis to open and close. The ball valve is primarily utilized in pipelines to shut off, distribute, and redirect the flow of media.
● Reasonable Design: A compact structure that effectively reduces installation space, allowing the valve to be flexibly utilized in various pipeline systems.
● Corrosion Resistance: Manufactured from high-quality materials, the valve offers excellent wear resistance and a long service life.
● Flange Connection: This connection method ensures a tight bond between the valve and the pipeline, reducing the likelihood of leaks and enhancing the system's sealing and safety.
