SIPOS Aktorik have replaced conventional actuation technology at a major water system in Portugal with their electric actuators. Selected for their ability to prevent water hammer, the actuators feature variable speed control to prevent the generation of damaging hydraulic forces.

Following successful product testing by Empresa Portuguesa das Águas Livres, SA Ltd (EPAL), the first batch of 18 SIPOS 5 Flash actuators was purchased. More actuators will be ordered during 2012 to provide advanced actuation technology for a number of feeder lines.

At the Castelo de Bode reservoir scheme, SIPOS’ actuation solution provides valve automation technology for the supply of drinking water: the system extends over 2100km from its source to the city of Lisbon. SIPOS’ products with PROFIBUS interface integrate with a highly automated SCADA system which centralises the operation and control of over 170 installations, including pumping stations and treatment plants.

SIPOS reports that the project confirms the company’s integration capabilities and reflects a growing trend of conventional electric actuators being replaced by Variable Speed Actuators (VSAs).
