Abstract: A method for operating a control valve using an HVAC actuator is described, the method comprises a circuit of the HVAC actuator executing the steps of: monitoring (S1) a rotation angle (ϕ) associated with a drive torque (Mdrive) applied by the HVAC actuator for moving the valve member; detecting (S2) a blocking of the control valve, if the applied drive torque (Mdrive) effects a change of the rotation angle (Δϕ) which is smaller than a threshold angle (ϕth); upon detection of the blocking, controlling the HVAC actuator to repeatedly change the applied drive torque (Mdrive) between a first torque value (M1) and a second torque value (M2); and controlling the HVAC actuator to periodically modulate (S4) the first torque value (M1) between a third torque value and a fourth torque.
