Product overview

Dd973 electric double clip multi-level metal hard seal butterfly valve adopts three eccentric structure. The valve seat and disc sealing surface are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has two-way sealing function. The product meets the national GB / T13927-92 valve pressure test standard. The electric double clip type metal hard seal butterfly valve adopts precise J-shaped elastic sealing ring and three eccentric multi-level metal hard sealing structure. It is widely used in gold treatment, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines with medium temperature ≤ 425 ℃It is used to regulate the flow rate and to regulate the flow rate on the industrial pipelines for gold treatment, electric power, petrochemical industry, water supply and drainage and municipal construction

Product features

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 3.service life under low and high temperature conditions.
4.The sealing surface of disc plate is made of hardfacing cobalt base cemented carbide, which is wear resistant and has long service life
5.Large size butterfly plate adopts quilting frame structure with high strength, large flow area and small flow resistance.
6.The valve has two-way sealing function. It is not limited by the flow direction of medium or affected by the space position. It can be installed in any direction.
The driving device can be installed in multiple positions (90 ° or 180 ° rotation), which is convenient for users.
