Double eccentric flange type anti-corrosion butterfly valve

 

 

 

This series of anti-corrosion butterfly valve is a new type of anti-corrosion butterfly valve developed by our company on the basis of eccentric vermicular valve according to the current market demand. This type of valve is a new type of anti-corrosion butterfly valve with advanced structure, safe and reliable, and long service life.

 

Features

1, fruit with mature technology, stable performance, good sealing performance of our factory soft seal butterfly valve as the basis, valve body, valve plate by no mold vulcanization technology for anti-corrosion treatment, with vulcanization layer performance stability, long service life, good corrosion resistance and other characteristics.

2. The butterfly valve parts are treated with anti-corrosion technology, which effectively avoids the corrosion of the medium to the valve.

3. This series of butterfly valves continue the characteristics of our company's soft-sealed butterfly valves that are easy to repair and can replace the sealing ring online without disassembling the valve.

4. This series of butterfly valves are not restricted by the flow direction of the medium during installation and have a two-way sealing function.

 

Scope of adaptation

This series of anti-corrosion butterfly valves can be used in corrosive media conditions, such as seawater desalination, seawater power generation, chemical industry, etc.
