Product Description

Stainless steel butterfly valve (also known as stainless steel flap valve) adopts three eccentric multi-layer metal hard seal structure, which is widely used in metallurgical, electric power, petrochemical, and industrial pipelines such as water supply and drainage and municipal construction with medium temperature ≤ 425 °C. For regulating flow and load fluid use. The valve adopts a three-eccentric structure, and the valve seat and the sealing surface of the disc are made of stainless steel with different hardness, which has good corrosion resistance and long service life.

Installation tips:

1. When installing, the disc should stop at the closed position.

2, the opening position should be determined according to the rotation angle of the disc.

3. Butterfly valve with bypass valve. Open the bypass valve before opening.

4, should be installed according to the manufacturer's installation instructions, the weight of the butterfly valve should be set a solid foundation.
