Electric part-turn actuators with integral controls for applications in the oil and gas industry Product description

The actuator specialist AUMA are one of the leading manufacturers of electric actuators, actuator controls and valve gearboxes for the automation of industrial valves in the oil and gas industry. AUMA have more than 45 years of experience in research & development and manufacture of electric multi-turn and part-turn actuators. AUMA manufacture their products in the two German plants, Muellheim and Ostfildern. Three service centers, respectively in Cologne, Magdeburg and Munich, have been set up to offer service support. 2,200 employees belong to the AUMA group worldwide. AUMA automate...

SGExC part-turn actuator with ACExC controls GS part-turn gearbox with SAEx .2 multi-turn actuator AUMA actuators for the oil and gas industry AUMA part-turn actuators are used wherever the automation of a valve requires a part-turn movement, e.g. when using butterfly valves or ball valves. For a part-turn movement, less than one rotation at valve input is required for a complete travel. A typical requirement is a swing angle of 90°. AUMA SGExC part-turn actuators AUMA SGExC part-turn actuators are designed to meet the special requirements in the oil and gas sector. They are approved...

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 AUMA corrosion protection is one of a kind in the world of actuators. Based on chemical preliminary wet treatment with subsequent double 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)....

OPEN-CLOSE duty and positioning duty AUMA SGExC actuators are suitable for open-close duty and positioning mode. Positioning duty Actuators for open - close duty are appropriate for automating shut-off valves. They are rarely operated; when operated, they cover the complete swing angle. The time difference between two travels can amount to minutes or even to months. One or several predefined intermediate positions are used to set the required flow rate through a pipeline for example. For this type of application, the intervals between two operations are generally considerably shorter than...

Switching off in the end positions One of the key actuator functions is the automatic cut-off once an end position is reached. Two different mechanisms are available for SGExC part-turn actuators and are applied depending on the type of valve. Limit seating Switching points for end positions are set in the actuator. As soon as the set switching point is reached, controls automatically switch off the actuator. Torque seating This type of seating is used if the valve has to be moved to end position CLOSED at a defined torque to ensure correct seating. As soon as the preset torque is applied...

Power supply, e.g. 400 V 3-ph AC current AUMA NORM With AMExC integral controls With ACExC integral controls TSC TSO 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...

Integral controls Actuators with integral controls are immediately ready for use. The controls are perfectly adapted to the actuator. As soon as the power supply has been established, the actuator can be operated via the operation elements on the local controls. The actuator can be completely set on site, without requiring direct connection to the DCS. Only operation commands and feedback signals are still exchanged between the control system and the actuator. Motor switching is performed within the device and without delay. The actuators can be equipped with AMExC or ACExC integral...
