APPLICATIONS WATER  Sewage treatment plants Water treatment plants Drinking water distribution Sewage disposal Seawater desalination Steel constructions for water systems Drinking water abstraction and distribution, as well as sewage disposal and purification are basic prerequisites for infrastructure development. Security of suppliy is crucial for modern water industry. Piping of different lengths and nominal diameters must be automated with a multitude of valve types. AUMA actuators are widely used in civil engineering constructions for water applications to operate weirs and sluice...

Tank farms Platforms Pipelines Refineries Pumping stations Oil & gas are crucial energy sources for the industry. They are extracted, processed, and distributed using most sophisticated technologies and procedures. Due to the high potential hazards for people and environment, strict sets of regulations must be observed within the oil & gas sector. AUMA are renowned in this industry on an international level, complying with the increasing market demands for vendor list approvals and explosion protection certificates. AUMA actuators fully meet the requirements of the oil & gas industry with...

WHAT IS AN ELECTRIC ACTUATOR? In process technology plants, liquids, gases, vapours, 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. Automating industrial valves Modern industrial applications are based on a high level of valve automation. This is the requirement for managing complex processes. The actuator positions the valve in compliance with operation commands issued by...

Requirement for diversity Process engineering plants with pipe systems and valve automation are required all around the globe. Not only types of plants and valves are crucial factors for electric actuators but also the climatic conditions in which they are operated. AUMA actuators guarantee reliable and safe service under most extreme environmental conditions. Requirement for reliability Process engineering plants are only efficient, economically viable and safe if all components involved provide reliable service during the entire lifetime. Many plants are scheduled for lifetimes of several...

SA MULTI-TURN ACTUATORS AND SQ PART-TURN ACTUATORS The actuation mode is considered a significant distinction factor between the different valve types. A typical example of multi-turn valves are gate valves. They require a defined number of turns at valve input for a complete valve stroke from CLOSED to OPEN and vice versa. Butterfly valves or ball valves are typically used if part-turn movements up to 90° are required for the entire travel. Globe valves are normally operated via linear movement. Furthermore, certain valves are operated via lever arrangements. In this case, we are talking...

SA multi-turn actuators In compliance with EN ISO 5210, a multi-turn actuator is capable of withstanding thrust applied to the valve and transmits torque to the valve for at least one revolution. In general, multi-turn actuators are required to perform more than one revolution. Consequently, gate valves are often equipped with rising valve stems. They are operated on the basis of several revolutions performed by the multi-turn actuator. Therefore, the multi-turn actuator is equipped with a hollow shaft housing the gate valve stem for these applications. SQ part-turn actuators In compliance...
