In 2021, a new counterweight assisted hydraulic actuating unit was installed at Klåvben HEPP to control the distributor. The counterweight unit is actuated by a hydraulic cylinder that raises and lowers the counterweight arm, which in turn provides a torque on the control shaft that opens and closes the distributor. In the event of a power failure, the counterweight ensures that the turbine shuts down quickly and in a controlled manner. The delivery also included a feedback transducer for the runner blade angle and wicket gate opening.
