A flanged flap with eccentricity is the best solution for regulating fluid flow in pipelines.

The principle of its operation is that the mechanism inside the cylinder with a rotation of 90 ° blocks the flow completely, and when turning with a smaller angle it is able to reduce the force of the flow.

The body parts and disc are made of high-strength cast iron, the connecting parts are made of stainless steel, and the packing material  is elastomer. The gate has epoxy protection, which reliably prevents the occurrence of corrosion processes.
