The throttle valve for ventilation Vents KR 250 is designed for manually closing or adjusting a circular air duct with a diameter of 250 mm. Using the damper, you can adjust the amount of air passing through the duct. For adjustment, a damper is used with an attached handle and the position of the damper is secured with a bolt.
The housing and the turning plate are made of galvanized sheet steel. For a tight connection with the air ducts, the dampers are equipped with rubber seals.
Installation
The design of the valve allows it to be mounted on round air ducts using clamps. When installing dampers with a servo drive, it is necessary to leave space for control access to the drive.
