Retractable sealed check valves RSKT
The RSKT tight check valves are designed for circular air ducts and prevent air backflow. The butterfly valves are made of galvanized steel in a "butterfly" design. Installation of the check dampers is quick and easy - they are inserted into the ductwork. The dampers are fitted with a double-edged gasket to ensure a tight seal around the perimeter of the damper.
