Main features: The closing component is composed of two main and auxiliary gate plates with interlocking inclined surfaces. When closed, under the action of the inclined surface, the main and auxiliary gate plates are stretched open, pressing tightly against the cover to seal the valve. Suitable for use as a closed-circuit device on pipelines with water and sewage as the medium, it is not allowed to be used for regulating flow and emptying
