This type of KVK dampers is used to shut off the air channels, as well as to regulate the air flow. The damper and valve body are made of galvanized steel sheet. The damper blade KVK-… M has a rubber seal, which ensures tight shut-off of the channel; damper KVK-… R is not intended for shutting off the valve. It is truncated from the sides, due to which a linearized dependence of the air flow through the valve is obtained in accordance with the angle of rotation of the damper. The valve body has rubber seals required for connection to air ducts or other ventilation system components.
The air dampers can be operated manually using a handle that allows the damper to be fixed in the desired position, as well as by means of an actuator.
The valves do not lose their functionality and continue to function in any spatial orientation.

KVK-M and KVK-R dampers for round air ducts:
Air dampers KVK- ... M are designed to regulate the air flow or shut off the air ducts. The valve body and flap are made of galvanized steel sheet. The damper blade is fitted with a silicone seal.Air dampers KVK -... R are designed to regulate the air flow, like a throttle-valve. The valve body and flap are made of galvanized steel sheet. The damper damper is made truncated from the sides, this design makes it possible to obtain a linearized dependence of the air flow through the damper depending on the damper rotation angle.
The casing is equipped on both sides with rubber seals for connecting air ducts or other components of the ventilation system.
The KBK air dampers are controlled using a manual or electric drive. To adjust the position of the damper manually, the valve is equipped with a handle with the ability to fix its position. The damper shaft is mounted on polyamide bushings.
Accessories: electric drive stand, electric drive.
