Auma manufactures electric actuators and secondary gearing sets for very large valves, in mines, water treatment, hydro electric, stored energy or power installations. All of the parts for the actuators and gearboxes are machined in house, without relying on third party vendors. The actuators may be combined with AC2 or ACV integral controls. The AC2 or ACV controls may be supplied with access to allow operation by digital signals, analogue signals or indeed any of the major 2 wire fieldbus systems. Generally the interfaces are already onboard and may be enabled by a software key. The allowance of both digital…
