D373h double clip hard seal butterfly valve

Product overview

D373h double hard seal butterfly valve meets the requirements of national standards JB / t8527-97 (metal hard seal butterfly valve), FB / T13927-92 (general valve pressure test) standards and other relevant standards of the valve. Combined with the advanced technology at home and abroad, it adopts the three-dimensional eccentric principle design, and the sealing ring adopts the multi-level structure of both hard and soft sealing, which is suitable for metallurgy, power and stone with medium temperature ≤ 650 ℃ Oil and chemical industry, air, gas, water supply and drainage and other medium pipelines are used as regulating fluid and cut-off fluid, with reliable sealing performance. It is the extension and development of universal butterfly valve to the field of medium pressure and high pressure.

Application and characteristics

D373h double clip hard seal butterfly valve is suitable for food, medicine, petrochemical, power plant, steel plant, industrial environmental protection water treatment, high-rise building, water supply and drainage pipeline as the best device for regulating flow and cutting off fluid.

1. The valve adopts three eccentric sealing structure, the valve seat and butterfly plate almost have no wear, with the sealing function of more and more tight

2. The seal ring is made of stainless steel, which has the double advantages of metal hard seal and elastic seal. It has excellent sealing performance, corrosion resistance and long service life, no matter at low or high temperature

3. The sealing surface of the disc plate is made of hardfacing cobalt based cemented carbide, which is wear-resistant and has a long service life

4. Large size butterfly plate adopts quilting frame structure with high strength, large flow area and small flow resistance

5. The valve has two-way sealing function. It is not limited by the flow direction of medium and the influence of space position. It can be installed in any direction

6. The driving device can be installed in multiple positions (90 ° or 180 ° rotation), which is convenient for users
