Features of ACTAIR EVO and DYNACTAIR EVO Series
KSB Group has launched a new generation of pneumatic 90° quarter-turn actuators. The double-acting and single-acting pneumatic actuators of the ACTAIR EVO and DYNACTAIR EVO type series are designed for actuating all types of part-turn valves, such as butterfly valves, ball valves, and plug valves.
Applications Across Various Industries
Applications covered by the actuators include water treatment, wastewater treatment, power generation, general industry, refinery engineering, and shipbuilding.
The double-piston actuators can be operated with compressed air to ISO 8573-1 from 3 to 8 bar. The maximum torque is 8000 Nm for the double-acting type series and 4000 Nm for the single-acting variant. The maximum ambient temperatures should be between -50 °C and +150 °C. With their IP68 enclosure, the actuators are suitable for use in a maritime environment. This means that – in the event of flooding – they will remain water-tight for about 169 hours at a depth of up to 30 meters.
The pneumatic connections comply with the NAMUR requirements.
As standard, the actuator is fitted with a position indicator and adjustable mechanical stops. The actuators are lubricated with silicone-free grease at the factory; their gear housings are made of anodized aluminum alloy. The actuators can be connected to higher-level process control systems with solenoid valves, positioners, and diverse digital and analog control units with their standardized interfaces.
