Electric flange hard seal butterfly valve

1Electric flange hard seal butterfly valveProduct Description:

The three eccentric hard seal butterfly valve series products are long-life and energy-saving butterfly valves developed by our company in 1996. The product complies with the national standard JB/T8527-97 Metal Sealed Butterfly Valve, GB/T13927-92 General Valve Pressure Test Standard, and other relevant valve standards. This product consists of main components such as valve body, butterfly plate, sealing ring, and transmission mechanism. The structure adopts a three-dimensional eccentric principle design, and a new processing technology that is compatible with elastic sealing and hard soft multi-layer sealing, which reduces the torque force of the butterfly valve during operation, achieving the functions of labor-saving and energy saving. Thus ensuring the overall reliability of corrosion resistance, high temperature resistance, and abrasion resistance.

IIElectric flange hard seal butterfly valveProduct Overview:

On the basis of introducing advanced technology, Shanghai Tingyang adopts precision J-shaped elastic sealing rings and three eccentric multi-level metal hard sealing structures, which are widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction with medium temperatures ≤ 425 ℃, for regulating flow and carrying fluids. This valve adopts a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life. The valve has a two-way sealing function and meets the national GB/T13927-92 valve pressure test standard.

3、 Product features:

1. This valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as viewed.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperatures, corrosion resistance, and long service life.
3. The sealing surface of the disc plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life
4. The large-sized butterfly plate adopts a frame structure with high strength, large overcurrent area, and low flow resistance.
5. This valve has a bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction.
6. The drive device can be installed in multiple stations (rotated 90 ° or 180 °) for easy user use.
