Check valve for ventilation Vents KOM1 500x300 is used to block a channel with a cross-section of 500x300 mmin a duct ventilation system when the fan is not working. The closure of the channel occurs under the own weight of the valve flap. The valve opens due to the movement of air flow through the channel.
The housing and the turning plate are made of galvanized sheet steel. The valve handle is equipped with a counterweight, with which you can adjust the sensitivity of opening and closing the valve.
Installation
The check valve is designed for installation in rectangular ducts of ventilation systems with the long side in a horizontal position. The plate should close on its own under its own weight. When placing a valve in a ventilation system, the direction of air flow must be taken into account.
