AUMA: GQB Series of Gearboxes

AUMA GQB SeriesAUMA has a new range of part-turn gearboxes, the GQB series. They have been specifically designed to meet the requirements for basic 90° applications with standard industrial valves such as butterfly and ball valves.

The housing incorporates a coaxial primary reduction gear as well as integral mounting flanges for the actuator, handwheel and valve. This considerably reduces the number of parts and the amount of material required, without compromising performance. End stops to limit the valve travel are accessible next to the output drive shaft. A patent-pending overload protection guarantees safety in case of excessive torque.

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 or dams.
