In sewage treatment, valves play a very important role and are the key units for various types of sewage treatment control.

WESDOM always promises our clients high-quality products. That’s why WESDOM products are popular in the international market.

Flange butterfly valves are widely used in production pipelines in water conservancy projects, water treatment, petroleum, chemical industry, urban heating and other general industries.

The butterfly plate must be in the closed position during installation to ensure that the butterfly plate does not collide with the pipe flange.
