Two way flanged brass cock valve
Plug valve is the valve through a fast switch, because the rotary movement between the sealing surface with a clean, and in the fully open can completely prevent contact with the fluid medium, so it usually can also be used with suspended particles of the medium. Another important feature of the plug valve is that it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even different channels of the four. This simplifies the design of piping systems, reduces valve usage, and requires some connection fittings in the equipment.
