mechanical efficiency and corrosion-proof housing/external parts.
Design initiatives have also been made by AUMA for gearboxes and the GS 630.3 part-turn gearbox has been developed. The new product provides 675 000Nm which is virtually double the capability of AUMA’s existing high torque gearbox solution, the GS 500.
Multi-turn operation
Understood to be the highest production unit on the market, the new AUMA gearbox incorporates all the benefits of the company’s existing gearbox range, namely high end-stop strength and adjustable swing angle of 80°–100° or multi-turn operation without end stops. The GS 630.3 addresses the challenges

of increasing pressure on energy supply networks and the plant manager’s need to reduce operational costs. To satisfy these demands, supply plants and pipelines are operating at ever higher pressures with larger pipe diameters. This, in turn, means increasingly high torques are required to operate the butterfly and ball valves used in these applications. AUMA recognises the importance of supporting
industry sector specialists. One example of such a relationship is with Framo and AUMA’s actuation technology has been
incorporated into a Framo Multiport Selector Manifold (MSM). The product has been adopted in offshore projects at the CNOOC Bohai Bay in China and with ONGC in India.
The new combined production and test manifold has also been selected by PDO Oman for use in desert environments. Designed to reduce the size of the test and production manifold, the MSM features a number of integral inlets which simplifies control requirements. Rotating flow path capabilities enables
production testing of individual wells with a minimum number of valves. A key feature is unique enclosure
protection afforded by the actuators – with all components contained in one housing, the technology is capable of withstanding extreme environmental conditions.

R&D facility
With a dedicated R&D facility at its manufacturing facility in Muellheim, AUMA confirms that actuation solutions will continue to evolve both as generic solutions and in partnership with industry specialists, such as Framo, a leading manufacturer and supplier of submerged pumps for the world tanker and offshore markets. AUMA also has established a world-wide network of subsidiaries and representatives. As actuation technology innovators, AUMA will continue to address the specific needs of the oil and gas industries. o
