The axis of the valve stem deviates from both the center of the disc and the center of the body, and the rotation axis of the valve seat has a certain angle with the axis of the valve body channel. It is widely used in industrial pipelines such as power, petrochemicals, water supply and drainage, and municipal construction for regulating flow and carrying fluid.

• The butterfly plate sealing ring is a soft and hard laminated metal plate, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperature conditions.

• Adopting a three eccentric structure, the valve seat and valve plate have almost no friction and a sealing function that becomes tighter as they close.

• The sealing surface of the valve body is made of welded stainless steel and drill based hard alloy. The sealing surface is wear-resistant and has a long service life.

• Unique structure, flexible operation, labor-saving, convenient, not affected by high or low medium pressure, reliable sealing performance, and long service life.
