ABSTRACT:
The invention concerns a regulator valve for stabilizing volume flow, especially in ventilation systems, with an adjustment flap (4) which is pivotable mounted in a flow conduit (2) and can be adjusted by a variable adjusting motor (12) and with a measuring probe (14) located in the flow conduit (1 resp. 2). In order that a reliable regulation and stabilization of the volume flow is possible independently of the arrangement and of the configuration of the conduit system upstream from the regulator valve, a turbulence grate (6) should be located upstream from the adjustment flap (4).
