Rotork supply flow control solutions to Wessex Water for multi-million upgrade project
支持联合国可持续发展目标6，清洁的水和卫生，并使世界流动到后代。
Wessex Water命令智能电动执行器支持一个5000万英镑的项目，以重建Durleigh水处理中心，该中心为40,000多名英国居民提供饮用水。这是旋转和Wessex水之间的框架协议的一部分。
萨默塞特郡的Durleigh水处理中心是Wessex Water的第二大地表水处理厂。它可以从Durleigh水库和Bridgewater和Taunton运河中处理原始水，但是近年来该地点的状况恶化了。这促使一个更新项目将改善治疗过程和生产的水。
Over 200 Rotork IQ multi-turn and part-turn operated actuated valves (some with IW Mk2 gearboxes) have been installed on almost all processes on the site. IQ3 actuators operate a wide range of valves, including butterfly valves that control the flow of raw water through a new main treatment building, inlet valves as the water enters from the reservoir and applications within the main treatment building such as Dissolved Air Flotation, Rapid Gravity Filters and Granular Activated Carbon Filters. They also operate valves within the second building on site (known as the “Low Lift Pumping Area”), a building that treats wastewater from the process, and a chemical building where final processes (including ultraviolet treatment) are undergone. A small number of compact, electric ROM actuators were also installed to provide simple on/off control within the main treatment building. All the actuators operate on a Profibus control network, providing control and feedback data about the valve and actuator using DP-V0 cyclic communications. The scheme will be Wessex Water’s first that is delivered to BIM (Building Information Modelling) level two, with the aim to use digital technology to work in a faster, safer and more efficient way. It is anticipated that the new centre will have an output range of 5 and 30 megalitres per day.
IQ3执行器由于其防水保护而非常适合供水。它们是双密封到IP66/68的。即使去除末端盖，内部电气也可以保护执行器的全部寿命。实时阀门和执行器性能在LCD显示屏上可见。Rotork应用团队为执行阀自动化所需的所有加工组件制作了设计和图纸。
