The three-way flanged ball valve and gate valve belong to the same type of valve, the difference is that their closing parts are a ball that rotates around the center line of the valve body to achieve opening and closing. The ball valve is mainly used in pipelines to cut off, distribute and change the direction of the flow of media.
● Reasonable Design: Compact structure, effectively reduce the installation space, so that the valve can be flexibly used in a variety of pipeline systems.
● Corrosion Resistance: The valve is made of high quality materials, with good wear resistance and long service life.
● Flange Connection: This connection mode makes the valve and pipeline tightly connected, not easy to leak, improve the sealing and safety of the system.
