Rotork supplies flow control solutions to Wessex Water for multi-million upgrade project

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 actuators are ideally suited to water applications because of their water ingress protection; they are double sealed to IP66/68. Internal electrics are protected from the ambient environment for the full life of the actuator, even when the terminal cover is removed. Real time valve and actuator performance is viewable on the LCD display. Rotork application teams produced the designs and drawings for all the machined components that were required to carry out the valve automation. Rotork www.rotork.com

the water that is produced. 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

Intelligent electric actuators have been ordered by Wessex Water to support a £50mn project to reconstruct the Durleigh Water Treatment Centre, which provides drinking water to over 40,000 UK residents. This is part of a framework agreement between Rotork and Wessex Water. Durleigh Water Treatment Centre in Somerset is Wessex Water’s second largest surface water treatment works. It treats raw water from the Durleigh reservoir and Bridgewater and Taunton canal, but in recent years the condition of the site has deteriorated. This prompted a renewal project that will improve the treatment process and

Witt-Gasetechnik introduces new ‘smart’ dome pressure regulator with integrated sensors

on the regulator and is transmitted via a network connection. In this way, key people can be alerted quickly if action is required. This ensures maximum operational reliability and process precision. Witt dome-loaded pressure regulators offer accuracy of pressure control compared to competitor products which according to the company typically show pressure “droop” i.e. at higher flows the outlet pressure drops off. With Witt regulators, the pressure curve remains practically unchanged over the entire range of flows.

The newDome 747 and 767 LE/S SMART offer Kv values of 3.6 and 30; a Kv value of 15 was already previously offered by the 757 model. Both products also offer a choice of 1", 2" or 3" connection options, and these devices can easily be retrofitted into existing gas supply systems. The smart sensor technology of the dome-loaded pressure regulators measures the inlet and outlet pressures as well as the gas temperature without the need for external sensors and transmitters and the software in the controllers calculates the gas flow based on the recorded data. The data obtained from the SMART models is shown in real time on a small display

Manufacturer of manufacturer of gas related equipment, Witt-Gasetechnik has launched two more dome-loaded pressure regulators with integrated sensors. The 747 and 767 LE/S SMART have been designed to make the monitoring of pressures, temperatures and flows easier than ever before. Following the successful market launch of the 757 LE/S SMART, with which Witt opened the door to Industry 4.0 for pressure regulators, the company is now presenting two new models of “smart” dome pressure regulators, which ensure even more transparency and process reliability in gas supply systems.
