Working principle and purpose of the product:

The American standard convex ear bidirectional sealing butterfly valve plate is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When it rotates to 90 °, the valve is fully open. Not only has it been well applied in general industries such as petroleum, gas, chemical, and water treatment, but it has also been used in the cooling water system of thermal power plants.

Product Structure Features:

① The unique design of three-way eccentricity ensures frictionless transmission between the sealing surfaces, extending the service life of the valve.

② Elastic sealing is generated by torque.

③ The clever wedge-shaped design enables the valve to have an automatic sealing function that becomes tighter as it is closed, with compensatory and zero leakage between the sealing surfaces.

④ Small size, light weight, easy operation, and convenient installation.

⑤ Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control.

⑥ Changing the material of the parts can be applied to various media and can be used for lining anti-corrosion (lining F46, GXPP, PO, etc.).
