$1 - Concentric Butterfly Valve


The concentric butterfly valve is characterized by the stem center, disc center and body center in the same position. Such structures are simple to make. The common wafer rubber lined butterfly valves are of this type. The drawback is that the disc and seat are always in the extrusion, scraping state, large resistance, fast wear. In order to overcome squeeze, scratch, seal performance, seat basically uses rubber or polytetrafluoroethylene elastomeric material, but also because seal material is used on the limit of temperature, this is why traditionally people think the butterfly valve does not bear high-temperature reason.
