摘要

The valve (1) has a valve housing (2) and two flow regulating bodies (40, 50) that are arranged in an area of flow openings (2.5, 2.6) and are adjusted by a common operating mechanism. An auxiliary regulating device is integrated in the operating mechanism such that the regulating body (50) is operated for changing a flow rate by the regulating device and the auxiliary regulating device. The flow rate of the flow regulating body (40) is unchanged by using the auxiliary regulating device during regulation.
