ELECTRICAL ACTUATORS FOR HYDRAULIC STEEL STRUCTURES AND HYDROPOWER BENEFITS OF ELECTRIC ACTUATORS AUMA supplies electric actuators solutions for automating shut-off and controls valves such as gate valves, butterfly valves, sluice gates, weirs and sluices. Easy installation, low operating and maintenance costs, as well as comprehensive functions of the integral actuators controls – these are only a small selection of the benefits of electric actuator technology as compelling automation solutions in hydraulic engineering installations. EASY TO INSTALL They just require power supply and a signal...

FREE OF OIL AND ENVIRONMENTALLY SOUND AUMA actuators consume little energy and are extremely low in maintenance requirements. This significantly contributes to their low Life-Cycle-Cost (LCC). Another asset: The actuators are free of oil and thus environmentfriendly since there is no risk of contamination by leaking oil. Furthermore, they are particularly suited for drinking water applications. ROBUST AND RELIABLE Thanks to their high-level IP68 enclosure protection and their excellent corrosion protection system, AUMA actuators withstand any weather impact. They excel in their reliable and safe...

APPLICATIONS FOR HYDRAULIC STEEL STRUCTURES AND HYDROPOWER Reliability and long product life are the prime requirements for operating weirs and sluices in hydropower engineering installations. The major requirement in actuator technology is withstanding the harshest climatic conditions even after decades and warranting perfect function on demand. AUMA offers individual electric actuator solutions for any application thanks to their comprehensive product portfolio of actuators, integral actuator controls and gearboxes. CIVIL ENGINEERING CONSTRUCTIONS FOR WATER APPLICATIONS For decades, AUMA actuators...

AUMA: YOUR COMPETENT PARTNER Hydroelectric power stations are in the spotlight for two trends: on the one hand the desire to harness the energy potential of running water as a clean source of energy, on the other hand the increasingly stringent severe environmental specifications. AUMA’s efficient and clean electric actuator technology importantly contributes to economical and ecological utilization of hydropower. We at AUMA are convinced by the trend-setting potential of the electro-mechanical actuation technology. We are extremely committed to find innovative solutions for all new applications...

WEIRS, DAMS AND LOCKS Weirs are installed for water level control of different water bodies and to ensure navigability of rivers and channels. Demands on reliability are, therefore, extremely high. Actual level control is executed by positioning the weir penstocks. As a general rule, electric actuators are used for their automation. Large strokes, long or fast operating times and virtually constant and elevated torque requirements across the complete travel are typical actuators requirements in this market segment. The situation is similar for locks since they have to ensure permanent availability...

SIMPLE FAIL SAFE SOLUTIONS SYNCHRONOUS OPERATION It is fairly easy to perform safety-related functions by means of electric actuators. Non self-locking actuator gearbox combinations can be installed: In case of power failure or an emergency signal, they automatically either close a weir thanks to gravity or open the gate in the case of fishbelly flap gates. Large sluice weirs are often driven from two sides. The selected actuator solution must secure that both sides move simultaneously during opening and closing thus avoiding gate panel jamming. AUMA offers various solutions for synchronous operation:...
