Electric triple eccentric hard seal butterfly valve

It adopts precision U-shaped elastic seal ring and three-eccentric multi-layer metal hard seal structure, which is widely used in metal pipes with medium temperature ≤425℃, electric power, petrochemical industry, municipal construction of water supply and drainage, etc., for regulating flow And cut off fluid use. The valve adopts a three-eccentric structure, the valve seat and the sealing surface of the butterfly plate are made of cast steel and stainless steel, which has good corrosion resistance and long service life.The valve has a two-way sealing function, and the product conforms to the national GB/T13927-92 valve Pressure test standard.

Features:

1. The valve adopts a three-eccentric structure, the valve seat and the valve plate have almost no wear, and the sealing function is tighter and tighter.

2. The sealing ring is made of stainless steel, which has the double advantages of elastic sealing of the metal seal box. It has excellent sealing performance under low and high pressure conditions, and has the characteristics of corrosion resistance and long service life.

3. The sealing surface of the butterfly plate adopts surfacing cobalt-based hard alloy, and the sealing surface is wear-resistant and has a long service life.

4. The valve has a two-way sealing function. It is not restricted by the flow direction of the medium during installation, nor is it affected by the position of the space. It can be installed in any direction. The driving device can be installed in multiple stations (rotation 90° or 180°), which is convenient for users.
