The lug/ wafer-type metal hard-seal butterfly valve is based on the advanced foreign technology introduced by our company. It adopts a precision J-shaped elastic sealing ring and a three-eccentric multi-layer metal hard-seal structure. It is widely used in the control of medium temperature ≤ 425℃. It is used to regulate flow and load-break fluids in industrial pipelines such as electric power, petrochemical industry, water supply and drainage, and municipal construction. The valve adopts a triple eccentric structure. The valve seat and disc sealing surfaces are made of different hardnesses and stainless steel. It has good durability and long service life. This valve has a sealing function and the product complies with the national GB/T13927-92 valve. Pressure test standards.

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 you look.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent performance at both low and high temperatures.
3. Excellent sealing performance, corrosion resistance and long service life.
4. The sealing surface of the disc is made of cobalt-based hard alloy surfacing. The sealing surface is wear-resistant and has a long service life.
5. The large-sized butterfly plate adopts a quilted frame structure, which has high strength, large flow area and small flow resistance.
6. This valve has a two-way sealing function. It is not restricted by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction.
7. The moving device can be installed in multiple positions (rotated 90° or 180°), making it convenient for users to use.
