Round single damper

Round single shut-off damper

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 shut-off 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 shut-off damper flaps.

Diverters are often used in co-generation systems at the output of the engine turbine for redirecting the exhaust gas to a stack or heat exchanger.

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