Large torque range 5 Solutions for a world in motion This brochure will provide both the beginner and the expert with an overview of the functions and applications of multi-turn actuator/part-turn gearbox SAEx/GS combinations. It can be used as the basis to determine the suitability of a device for the chosen application. This brochure deals mainly with the device characteristics arising from the combination of both devices. For detailed information on SAEx multi-turn actuators refer to brochure: ■ Product description Electric multi-turn actuators with ntegral controls for applications in...

The environmental conditions in the oil and gas industry are mostly extreme. Salt-laden air in offshore applications, aggressive atmospheres in refineries or rough operation AUMA devices must operate reliably over many years without major maintenance requirements under all conditions. For this reason, AUMA have focussed on making their devices resistant to the most unfavourable conditions and have adapted protective measures to the state-of-the-art technology. Ambient temperatures AUMA actuators are used in both hot and cold environments. Adapted versions with large temperature ranges are...

Corrosion protection Efficient corrosion protection is a major factor in the guarantee of a long service life. The AUMA corrosion protection system is based on double-layer coating. In compliance with the corrosivity categories according to EN ISO 12944-2, various AUMA corrosion protection levels are provided to suit the different applications. Colour The standard colour is silver-grey (similar to RAL 7037). Other colours are possible on request. Gearboxes in size 160.3 and larger are equipped with primer coating; factory finish coating is available as an option. AUMA Classification of...

[6] GS part-turn gearbox variants Four variants enhance options for optimum adaptation. This is due to the arrangement between worm shaft and worm wheel and the direction of rotation at output drive, with reference to a clockwise rotating input shaft. ■ LL: Worm shaft left from worm wheel, counterclockwise rotation at output drive (red arrow) ■ LR: Worm shaft left from worm wheel, clockwise rotation at output drive (blue arrow) ■ RL: Worm shaft right from worm wheel, counterclockwise rotation at output drive (red arrow) ■ RR: Worm shaft right from worm wheel, clockwise rotation at output...

Design principle [5] Pointer cover Th l i id i f i The large pointer cover provides information on the valve position. It continuously follows the valve movement and consequently serves the purpose of running indication. In case of high enclosure protection requirements, AUMA recommend replacing the pointer cover by a protection cover [5a]. The protection cover is required for buried service. [6] Coupling Th li bl i i The separate coupling enables easier mounting of the gearbox to the valve. Upon request, the coupling is supplied with a suitable hole for the valve shaft. The coupling with...

[9] Flange for mounting the multi-turn actuator In compliance with EN ISO 5210 or DIN 3210 As an alternative, a handwheel shaft can be fitted to mount a handweel when dealing with a manually operated valve. | 12

[1] GS part-turn gearbox Size GS 200.3 with primary reduction gearing is shown. [2] Gearbox housing The housing is made of cast iron. If extreme loads from outside have to be considered, AUMA recommend using spheroidal cast iron housings. [3] Worm wheel and worm shaft They form the core components of the gearbox. The design allows high reduction within one gear and has an important self-locking effect thus preventing valve position displacement in case external forces act upon the closing element. As standard, the worm wheel is made of spheroidal cast iron. Certain applications require the...
