Multi-turn actuators
The "small" electric globe valve actuator range with integral controls. All parameters are directly set at the actuator. The controls contain switchgear, power supply unit, interface to the DCS. The controls automatically switch the actuator off once the valve end position is reached, motor overheating is detected or a torque overload has occurred.
All housing components are made of bronze, all external screws are made of stainless steel. This ensures complete resistance against seawater even over a longer time period.
The SVM actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the SVMR actuators for modulating duty (class C) S4 - 40%.

Multi-turn actuators
The TIGRON is a multi-turn actuator with classic mission: Automation of gate valves with/without rising stem, of globe valves (double block and bleed valves) and in combination with part-turn gearbox of butterfly valves and ball valves.
Virtually unlimited stroke
Rising stems are led through the hollow shaft of the multi-turn actuator which drives the stem in combination with the output drive type A. The stem protection tube protects the stem from pollution and people from injuries.
Open-close duty, positioning duty and modulating duty
TIGRON actuator versions are available for all types of duty. Combinations with multi-turn gearboxes In combination with GK or GST gearboxes, torques up to 16,000 Nm can be reached.
Modular AUMA scheme
Six gearbox type ranges are part of AUMA’s product portfolio. They are ideally suited to complete and enhance TIGRON’s application range even to other valve designs. This includes numerous butterfly valves or the conventional ball valves of the oil and gas industry requiring a part-turn movement of mostly 90 degrees. In these cases, TIGRON is combined with AUMA part-turn gearboxes.
AUMA linear thrust units convert TIGRON’s multi-turn movement into a thrust movement which is required for globe valve automation.

Part-turn actuators
With the FQM fail safe unit, AUMA offers innovative and safe actuator solutions for automatic operation of valves in case of emergencies making use of stored mechanical energy.
Constant torque characteristics across the overall torque range.
The spring is not operated during standard operation. As a consequence, actuator sizing can be relatively small.
The end position switches are automatically set during the setting procedure of end positions OPEN and CLOSED and do not require separate adjustment.

Part-turn actuators
One solution for gate, butterfly, ball/plug and globe valves. Compact actuators with intelligent functions as platform concept for tailored automation solutions.
Each PROFOX is equipped with a centrally located LED: The FOX-EYE. It provides clearly visible information about both actuator and valve status. The FOX-EYE display scheme can be configured by the user as required.

Part-turn actuators
When combining SA multi-turn actuators with GS part-turn gearboxes, the combination acts as electric part-turn actuator fulfilling higher torque requirements.
Thus, these combinations represent a complement to the SQ part-turn actuators with their 2,400 Nm torque range limit.

Part-turn actuators
The "small" electric part-turn actuator range with separate MEC controls.
All parameters are directly set at the MEC controls. The controls contain switchgear, power supply unit, interface to the DCS. The controls automatically switch the actuator off once the valve end position is reached, motor overheating is detected or a torque overload has occurred.
All housing components of the actuator are made of bronze, all external screws are made of stainless steel. This ensures complete resistance against seawater even over a longer time period. The housing of MEC controls is made of aluminium provided with AUMA powder coating also achieving a premium corrosion resistance.
The actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the variant for modulating duty (class C) S4 - 40%.

The controls automatically switch the actuator off once the valve end position is reached, motor overheating is detected or a torque overload has occurred.
All housing parts are made of aluminium. For this reason, the actuators are very low in weight.
The SGC actuators are designed for open-close duty and positioning duty (classes A and B) / (short-time duty S2 - 15 min), the SGCR actuators for modulating duty (class C) S4 - 40%.

Part-turn actuators
Explosion-proof devices must be used in plants where potentially explosive atmospheres are likely to occur. These devices are designed so that they will not act as an ignition source. They neither generate ignition sparks, nor hot surface temperatures.
Certification is performed in close collaboration with national and international certification bodies.
