The concentricbutterfly valveis characterized by the stem center, disc center and body center in the same position. Such structures are simple to make. The common wafer rubber linedbutterfly valvesare 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.

Therefore, the centralbutterfly valveis basically under the condition of temperature below 60 degrees and pressure below 25 kilograms. The simple structure of thecentric butterfly valvefocuses on the sealing of the rubber seat and the sealing between the rubber seat and the stem. Every middle linebutterfly valvedelivered by ZhengFeng will not give up the strength and pressure test process of each one because of its simplicity, thus ensuring the perfection of this kind of valve. Due to its simple structure, ZhengFeng also pays special attention to its appearance.
