The butterfly valves BVA, BVG and BVH are designed for controlling volume flows of gas, cold and hot air, as well as flue gases in gas and air applications. These control valves are suitable for control ratios up to 10:1 and, equipped with an actuator, can be used for flow control in modulating or stage-controlled combustion processes.

For plug-and-play applications, these control valves are available as pre-assembled assemblies with IC servo motors under the type designations IBA, IBG and IBH.
