New GQB compact gearbox type range

A new range of part-turn gearboxes, the GQB series, extends the gearbox portfolio of electric actuator manufacturer AUMA. Engineered and manufactured in Germany, GQB gearboxes have been specifically designed to meet the requirements for basic 90° applications with standard industrial valves such as butterfly and ball valves. All components within the power drive, like the worm wheel and worm shaft, are surface hardened to further increase wear resistance. In addition, all housing parts are powder-coated using AUMA’s extremely corrosion-resistant two-layer powder coating system. The housing incorporates a coaxial primary reduction gear as well as integral mounting flanges for the actuator, handwheel and valve. www.auma.com
