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.

Therefore, the central butterfly valve is basically under the condition of temperature below 60 degrees and pressure below 25 kilograms. The simple structure of the centric butterfly valve focuses on the sealing of the rubber seat and the sealing between the rubber seat and the stem. Every middle line butterfly valve delivered 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. The ductile iron butterfly valve adopts advanced casting process of inner and outer coating sand, which ensures that every casting mark on the valve body and even the handwriting on the small 2-inch valve body is clearly visible.Awwa c504 butterfly valve manufacturersin China are abundant on the pursuit of higher quality, on the one hand, is to let the customer can get free maintenance rate in terms of use of convenient and simple relieved, on the one hand is to hope that in the long term is abundant brand can be set up in the field of global water butterfly valves, so we would like the attitude of benchmarking to establish the brand, to make our products.
