What is a fluorine-lined plug valve?

Since the movement between the sealing surfaces of the plug valve has a wiping effect, it can completely prevent contact with the flowing medium when it is fully opened, so it can usually also be used for medium with suspended particles. Another important feature of the plug valve is that it is easy to adapt to the multi-channel configuration, so that one valve can obtain two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valves, and some of the connection fittings required in the equipment.
