RECTANGULAR CHECK VALVE TYPE КОП

Check rectangular dampers for ventilation systems are designed to prevent air flow through the openings to the switched off fans (from the switched off fans) when the fans are connected to the manifolds.

The valve design consists of a body, inside which a blade is installed on the axle shafts. The axis of rotation of the blade is displaced relative to the axis of symmetry, due to which, when exposed to the air flow, a moment arises that turns the blade and sets the valve to the open position. When the air movement stops, the blade returns to its original position with the help of the counterbalancing lever with the load, thus closing the valve.                      The valves can be installed both in a vertical position with an air speed of at least 4 m / s, and in a horizontal position with an air speed of at least 6 m / s. Check valves can be operated at operating medium temperatures from -40 ° C to + 45 ° C. The environment and air must not contain aggressive gases and vapors that destroy the materials of the product. Check valves are manufactured in climatic versions for operation in regions with moderate У(moderate) and УХЛ (boreal) climates and location categories 1, 2, 3 and 4 according to GOST 15150 .
