The turbine butterfly valve complies with the national standards JB/T8527-97 (Metal Sealed Butterfly Valve), GB/T13927-92 (General Valve Pressure Test), and other relevant valve standards. This product consists of main components such as valve body, butterfly plate, sealing ring, and transmission mechanism. The structure of the D343H hard sealed butterfly valve adopts the three-dimensional eccentric principle design, and a new processing technology that is compatible with elastic sealing and hard soft multi-layer sealing reduces the torque force of the butterfly valve during operation, achieving labor-saving and energy-saving functions. Thus ensuring the overall reliability of corrosion resistance, high temperature resistance, and abrasion resistance.
The purpose and characteristics of turbine butterfly valve:
Turbine butterfly valves are suitable for regulating flow and cutting off fluid devices in food, medicine, petrochemicals, power plants, steel mills, industrial environmental water treatment, high-rise buildings, and water supply and drainage pipelines.
1. This turbine butterfly 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 turbine butterfly valve has 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.
