Rotork IQPro intelligent electric valve actuators have been specified for a drinking water supply upgrade project for the benefit of two million consumers in the Harz Region of northern Germany.

Rotork IQ isolating and IQM modulating actuators are being installed for the control of reservoir and dam valves at Ecker and Ederdam in a project undertaken by Harzwasserwerke.

The IQM actuators are operating specialised needle valves of German manufacture demanding highly accurate positioning and IP68 watertight and temporarily submersible environmental protection for long-term reliability.
