In the 50 years since it was founded Rotork has become the name for excellence in the field of valve, sluice gate and damper actuation products for the oil, gas, power, water and waste treatment industries-worldwide.

Rotork has the experience, know-how and product range to deliver virtually any actuation solution from compact, manually operated gearboxes, to large, highly specified actuators for use in extreme temperature and hazardous environments.


Electric actuators operating gate, globe, ball and butterfly valves determine the rhythm of flow. They are integrated into control systems and respond to signals. Actuators are linked to control or monitoring consoles, or they rely on their own intelligent electronics.

Where there is flow there is AUMA.


Servovalve is a company specialized in design and production of hydraulic and pneumatic actuators for industrial valves. The company was established in 1976 and, since its birth, has designed and produced standard and special actuators for every kind of valve, for severe and heavy duty service and for every environmental conditions.

Servovalve actuators are used in the most advanced fields, such as nuclear, geothermal and conventional power units, offshore or onshore oil and gas, chemical industries and refineries. Servovalve design full control systems and complete units for special applications in on-off or modulating executions equipped with pneumatic, hydraulic and electric equipment, hydraulic power units, emergency accumulators, fail safe circuits.


EMG Automation GmbH was created in 1946 as a subsidiary of Nationale Automobilgesellschaft (NAG),a wholly owned subsidiary of AEG. at Wenden.

Wherever liquid, gaseous or powdery medium is flowing through pipe-work, several kinds of valves are used to shut off or to regulate the rate of flow.

For reliable remote operation of these valves which may be globe, gate, ball or butterfly valves, DREHMO electromechanical valve actuators are globally successfully on service for several decades.

Power generation, water treatment, oil and gas production and distribution as well as the chemical and the petrochemical industry are fields of application for DREHMO valve actuators
