Check valve for ventilation Vents KOM 150 type 'butterfly' made of galvanized steel, valve blades made of aluminum. The valve has two spring-loaded petals, which open under the influence of air flow; when the air supply stops, the spring closes the cross-section of the air duct. Such valves are used in supply and exhaust ventilation systems.
Installation
The design of the valve allows it to be mounted on round air ducts using clamps. The rotation axis of the valve petals must be vertical. When placing a valve in a ventilation system, the direction of air flow must be taken into account. The Vents check valve, which will be used in supply ventilation, must be insulated to avoid the formation of condensation on it.
