This check valve is designed for an absolutely precise installation in round ventilation ducts; the check valve is pushed into the pipe and does not get installed between the pipes, as it is common with other systems. On one side the check valve is provided with a circular, precise rubber seal ring, which ensures that the check valve closes tightly.

A check valve (or a backwater valve) is needed to prevent the reversal of airflow. At the same time, it also prevents insects or rodents from entering the ventilation system.

The installation is very easy: just push the internal check valve at a straight angle into the desired ventilation pipe.

External diameter (rubber seal): 125 mm
