Rotork actuators chosen for water-supply upgrade

A Rotork Controls product story

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.

According to the company, the double-sealed IQ actuator offers environmental integrity, together with the simplicity of non-intrusive commissioning and the benefits of operational data logging for predictive maintenance.

It also provides responsive, positional accuracy, the 1,200-starts-per-hour duty rating of the Rotork IQM modulating actuator design and the flexibility for remote programming and monitoring facilitated by the IQ's control specification.
