AUMA has been developing and building electric actuators and valve gearboxes for 50 years and is one of the leading manufacturers in the industry.
Energy sector, water industry, petro-chemical industry and users from the most diverse industries worldwide rely on technologically sophisticated products by AUMA.
AUMA electric actuators are capable of operating all types of quarter-turn valves (butterfly, ball and plug) and multi-turn valves (gate, globe, sluice gate and pinch). AUMA actuators are also widely used to operate dampers (louver, guillotine and diverter). Actuators can be furnished for both open/close and modulating service. Integral motor controls and control accessories are available to interface with a wide variety of plant control systems.
AUMA Actuators, Inc. is headquartered near Pittsburgh, PA. AUMA’s Quality System is in compliance with the requirements of ISO 9001. A complete network of sales and service support is available throughout North America. Regional offices are located in the Northeast, Southeast, Midwest, Gulf Coast and West Coast. Representatives and distributors are located throughout the United States, Canada and Mexico.
In process technology plants, liquids, gases, vapors, and granulate need to pass through pipelines. Industrial valves are used to inhibit or release medium flow as well as to control the resulting flow rate by opening or closing the valves. AUMA actuators are remotely controlled from the control room to operate valves.
Electric multi-turn actuators by AUMA are used e.g. for the automation of gate valves or globe valves. They are the most versatile products within the AUMA family.
Electric part-turn actuators by AUMA are used where an automatic, electrically operated movement at a swing angle of less than 360 ° has to be implemented as it is the case for valves like butterfly and ball valves.
To perform linear movements, e. g. in case of globe valves, the multi-turn actuator SA … can be combined with the linear thrust unit LE, forming an electric linear actuator. In case a lever arrangement has to be operated, the linear thrust unit can be mounted on a base.
Multi-turn gearboxes can be formed by combining multi-turn actuators SA … with AUMA spur and bevel gearboxes to increase the torque or to reposition the output shaft. The gearboxes can of course also be used on manually operated valves.
Product selection in favor of actuators with integral controls saves time-consuming project planning, installation, and additional documentation which is required when selecting external controls.
Parallel control, field bus, or both for reasons of redundancy? When opting for field bus, which protocol to use? Irrespective of your decision on the interface, AUMA actuators can be equipped with the suitable interface to match all systems established within process control engineering.
