High-precision AUMA actuators for heating/cooling and m

AUMA’s compact electric actuator ranges offer highly precise, robust and reliable flow control solutions for chemical, food, and other industries. Applications include demanding temperature control systems, for example preheating and cooling systems as well as low-temperature processes, and fluid metering systems. AUMA offers two product families for these challenging applications that depend on precise and high-speed valve position control to ensure absolute reliability and homogeneous product quality: Basic Range and Smart Range actuators. Both ranges are designed for harsh industrial environments and offer outstanding precision, reliability and availability, even under difficult process conditions. Their compact design makes them ideally suitable for space constraints and small valves. A handwheel for emergency operation is included as standard.

The Basic Range comprises SBA linear actuators and ED/EQ part-turn actuators. They offer simple control and essential functions as well as feedback signals, paired with robust design. Operation commands and setpoints are implemented by means of binary or analogue voltage or current signals.

SBA linear actuators provide high positioning accuracy and are ideally suited for modulating applications. Covering a thrust range from 0.6 kN to 25 kN and a stroke range from 35 mm to 100 mm, they are often deployed in heating and cooling systems.

ED/EQ part-turn actuators are the perfect choice when precise opening, closing or control are required for shut-off butterfly and ball valves or venting and flue gas dampers. They cover a torque range from 24 Nm to 600 Nm and swing angles from 90° to 180°.

AUMA’s Smart Range includes SDL/SDG linear actuators, SVC globe valve actuators and SGC part-turn actuators. All these actuators are equipped with variable-speed motors that provide soft starts and stops, ensuring gentle treatment and long life for all mechanical components. Variable-speed operating profiles, meanwhile, help to avoid critical pressure surges and cavitation. Parameter setting via software is another key feature, and both Modbus RTU and Profibus DP interfaces are available.

SDL/SDG linear actuators provide thrusts from 4 kN to 15 kN, with strokes from 55 mm to 300 mm. They work over a wide range of input voltages, so they are insensitive to voltage fluctuations. Thanks to their extremely low power requirements, the devices can easily be supplied by self-sufficient power systems such as solar PV. SVC globe valve actuators offer torques between 10 Nm and 100 Nm, with strokes from 60 mm to 70 mm. SGC part-turn actuators provide torques between 25 Nm and 1,000 Nm and swing angles between 82° and 98°.
