Valves Air, iris, etc.

Air valves are used to regulate the volume of air flow passing through the duct or to completely stop its supply. The most widespread are in supply ventilation systems in rectangular ducts.

A 400, 500, 600, 700, 800, 900, 1000 and others .

Unified air dampers are used to control the volume of air in the ventilation system channel.

D 100, 125, 160, 200, 250, 315, 355, 400, 450 and others .

• The air dampers are unified. Technical description.

Smoke extraction valves are used in ventilation systems. They ensure the removal of smoke from the room in the place where the fire occurred. In addition, smoke extraction valves are used to supply fresh air to rooms protected from smoke.

Ah 250, 300, 350, 400, 450, 500, 550, 600, 700 et al .

Fire-retaining valves allow to prevent the spread of fire and ignition products through the duct system in the event of a fire in the building. The fire-retaining valve is a structure made of a galvanized housing, a flap, a drive that rotates the flap, and a temperature sensor.

D 200, 250, 315, 355, 400, 450, 500 and others .

• Fire-retaining valves. Technical description.

Iris valves regulate the amount of air passing through the ventilation system and allow measuring its flow. These functions are performed thanks to an iris diaphragm placed in a round valve body.

Models: IRIS 100, IRIS 125, IRIS 160, IRIS 200, IRIS 250, IRIS 315, IRIS 400, etc.

• Iris valves. Technical description.
