The set of dampers - special design diverters

Sets of two flap dampers with one drive in one body (diverters) are designed for redirecting gas streams (e.g. exhaust gas, air) to piping branches. These devices may be operated both in two-position mode (one flap damper closed, while the second is open and vice versa) and for smooth gas flow control in one or in the second channel.

Depending on the customer requirements, many types of seals may be used to achieve higher tightness of damper flaps, also execution with sealing air is possible with tandem blade.

Diverters in special design have for example variable duct diameter and different branching angles, rectangular section, one blade execution with offset shaft and etc.

The diverters may be driven by any type of actuators designed for valve drives.

The product is ideally suited for customised solutions. It was designed in response to the needs that other flap dampers could not satisfy.
