The AUMA SAEx multi-turn actuators cover a torque range between 10 Nm and 16,000 Nm. In combination with GS part-turn gearboxes, torques up to 675,000 Nm can be achieved. This large torque range ensures that AUMA products are suitable to automate valves of various sizes and pressure levels within any plant. All actuators are integrated into the DCS using standardised control technology.

AUMA Generation .2 - New electric multi-turn actuators and actuator AUMA actuators and actuator controls are widely used in process plants throughout the world. Their highly developed technology and proven reliability guarantee accurate long-term performance in a wide variety of applications. Generation .2 represents a significant development for the increasing demands in process plants within the oil and gas industry. The modular structure provides the perfect combination of multi-turn actuators and appropriate actuator controls. Using standardised components, a customised solution can be developed...

controls Improved handling and operation The user friendliness for Generation .2 actuators was enhanced. ■ The improved AUMA handwheel activation allows single-handed handwheel operation and valve position adjustment by applying minimal force. Activation of manual operation can be signalled to the control room. ■ The AUMA motor plug/socket connection is now available throughout the complete Generation .2 series. ■ One single adjustable reduction gearing set within the control unit for all conventional stroke ranges Precision and control accuracy An improved mechanical structure and reduced mechanical...

The environmental conditions in the oil and gas industry are 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 has focussed on making AUMA devices resistant to the most unfavourable conditions and has adapted protective measures to the state-of-the-art technology. Enclosure protection IP 68 AUMA devices of Generation .2 are supplied with improved enclosure protection IP 68 in compliance with EN 60529. IP...

Corrosion protection AUMA corrosion protection is outstanding in the world of actuators. Based on chemical preliminary treatment with subsequent double-layer powder coating of individual parts, the standard corrosion protection already efficiently protects against corrosion even under the most unfavourable conditions while providing high mechanical resistance. 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...

Open-close and modulating duty Valves are subdivided in shut-off valves and modulating valves. ■ In general, shut-off valves are either open or closed. They are rarely operated; when operated, they cover the complete stroke. The interval between two travels can amount to minutes or even to months. They are controlled by means of the binary signals OPEN and CLOSE. This type of duty is classified as open-close duty. ■ Modulating valves are used to set a default variable being constantly verified and adjusted at short intervals. Control takes place by means of a continuous setpoint, e.g. a 0/4 –...

Switching off in the end positions Protective functions Irrespective of whether the actuator is operated in open-close or modulating duty, the device must automatically switch off when reaching an end position. Two different switch-off mechanisms are available and are applied depending on the type of valve. If an excessive torque is applied during travel, e.g. due to a trapped object or deposits within the valve, the controls switch off the actuator to protect the valve. ■ Thermal motor protection Limit seating As soon as the preset switching point in one end position is reached, the controls...

NORM AMExC ACExC L1 L2 [1] Power supply e.g. 400 V 3-phase AC current TSC TSO PE L3 RO LSC LSO RC M Basics - Controls concepts In principle, AUMA actuators may be integrated within any automation system. The state-of-the-art solution is to equip the actuator with integral controls to eliminate the time-consuming and costly engineering, installation and documentation for external controls. A further benefit in favour of integral controls is the easy commissioning. External controls For this controls concept, actuators contain no or only few electronic components. All actuator signals, limit switch...
