PROCESS. The renowned German magazine PROCESS has recognised AUMA GQB part-turn gearboxes as a top product of 2018. The AUMA innovation is rated second out of the top ten products in the valves category. The ranking is based on visitor responses on the magazine’s online portals www.process.de and www.process-worldwide.com.
Launched in 2017 for simple 90° applications with standard butterfly and ball valves, GQB gearboxes combine compact design with exceptional value for money. In 2018, the gearbox range was extended and now covers torques from 3,000 Nm to 84,000 Nm.
Engineered and manufactured in Germany, GQB gearboxes feature high manufacturing quality, overload protection and maintenance-free operation. The integral primary reduction gear and integral mounting flanges considerably reduce the parts count without compromising performance. The compact units are protected from corrosion by a high-quality powder coating including both input and output flanges. Inside, all drive components are hardened for long life.
The GQB gearboxes are used in combination with AUMA SA multi-turn actuators. They are ATEX-approved for use in potentially explosive atmospheres.
The GQB range complements AUMA’s proven GS part-turn gearboxes, which will continue to be used for demanding applications with special valves and for special requirements, for example in hydropower plants, weirs and dams.
