AUMA actuators are used worldwide; in all climatic zones, in industrial plants of all kinds under special local ambient conditions. AUMA devices have to operate reliably and for a long time under any conditions without requiring major maintenance work. For this reason, AUMA have focussed on making AUMA devices resistant to the most unfavourable conditions and have adapted protective measures to the state-of-the-art technology. Enclosure protection Multi-turn actuator with mounted gearbox SA multi-turn actuator and GS worm gearbox combinations are supplied in enclosure protection IP 68-3...

Corrosion protection Efficient corrosion protection is a major factor to guarantee 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...

Modular concept AUMA's claim is to be able to offer automation solutions to suit any valve. The product range consisting of sophisticated components forms the basis for many combination options due to standard d interfaces. [2] [1] SA .2 multi-turn actuators They play a crucial role within the product range. The speed range comprises 4 – 180 rpm, their torque range covers 10 – 32,000 Nm. [2] Integral controls Actuators with integral controls AM or AC are immediately ready for use. The integral controls contain switchgear units, power supply unit, interface to the D0CS and the ability to...

[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...

It continuously f ll 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.

[7] Valve mounting flange In compliance with EN ISO 5211. [11] [10] [9] [8] Primary reduction gearing (option) The primary reduction gearings utilise planetary or spur gear stages to reduce the required input torque. [9] Flange for mounting a 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 gearboxes 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...
