Background

A plug valve is a quick-opening and quick-closing straight-through valve which is also commonly used for media with suspended particles, since the movement between the rotary sealing surfaces has a wiping action, while contact with the flowing medium is completely prevented at full opening. Another important feature of a plug valve is that it is easily adaptable to a multi-channel configuration such that two, three, or even four different flow paths can be obtained for one valve. This simplifies the design of the piping system, reduces valve usage, and requires some connection fittings in the equipment.
