Hard metal seal butterfly valve，Hard seal butterfly valve，Butterfly valve

Product features:

The clamping butterfly valve is mainly composed of valve body, butterfly plate, valve shaft, valve body seal ring, shaft, self-lubricating bearing, drive device, etc., with the following characteristics:

1. Unique structure, small and light, easy to operate.

2. Adopt three-dimensional eccentric structure, the sealing surface of the butterfly plate and the seat has high processing accuracy. When the butterfly plate is opened, the sealing surface is detached. The butterfly plate is almost frictionless in the process of closing, and it is easy to close. With the function of self-locking, self-sealing performance, sealing performance is stable and reliable.

3. The sealing pair (butterfly seal ring - valve body seal ring) material is stainless steel, after special treatment, with metal hard seal and elastic seal double advantages, corrosion resistance, wear resistance, high temperature resistance, long service life.

4. The design of "radial dynamic balance sealing structure" is adopted, which makes the opening resistance of the butterfly plate very small and reliably realizes the two-way sealing zero leakage of the butterfly valve inlet and outlet. In the process of opening and closing, the sealing surface of the butterfly plate can be quickly completed along the 360° circumference, and the sealing action of automatically matching the close contact can be realized quickly and accurately.

5. The flow direction design of the butterfly plate has high strength, large flow area, small flow resistance and energy saving.

6. Reliable two-way sealing function, is the pipeline system requires two-way cutting products, installation is not limited by the flow of the medium, is not affected by the spatial position, can be installed in any scheme.

The metal sealed butterfly valve adopts a new type of "oblique elliptical butterfly plate radial dynamic balance sealing structure ", which reliably realizes the positive and negative sealing zero leakage of the metal hard sealed butterfly valve, especially suitable for the engineering with high reverse sealing requirements, and is truly a high-tech product with the international leading level. High performance bidirectional metal seal butterfly valve is widely used in metallurgy, hydropower, thermoelectric, heat, urban water supply and drainage, farmland drainage and irrigation industries, the use of medium for gas, steam, air, water, etc., in the pipeline system, for cutting or connecting media.
