The shape of the valve plug of the cast iron three-way plug valve can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the conical valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve light, but at the same time they also produce certain losses. The plug valve is most suitable for cutting off and connecting media and for diversion, but it can sometimes be used for throttling according to the applicable properties and the erosion resistance of the sealing surface. Since the movement between the sealing surfaces of the plug valve has a wiping effect and can completely prevent contact with the flowing medium when fully opened, it can also be generally used for media with suspended particles. Another important feature of the plug valve is that it is easy to adapt to multi-channel structures, so that one valve can obtain two, three, or even four different flow channels. This can simplify the design of the pipeline system, reduce the number of valves, and some connection accessories required in the equipment.
