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.
Rotork’s order has been won on technical merit and competitive pricing in the face of fierce competition from European actuator manufacturers. Rotork’s German company successfully demonstrated to the valvemaker the environmental integrity of the double-sealed IQ actuator design, together with the simplicity of non-intrusive commissioning and the benefits of operational data logging for predictive maintenance.
The valvemaker was also impressed with the responsive, positional accuracy and the 1,200 starts per hour duty rating of the Rotork IQM modulating actuator design as well as the flexibility for remote programming and monitoring facilitated as standard by the IQ’s control specification.
