Product Description
- The rotary actuator is suitable for pneumatic control of valves in chemical, petrochemical and industrial plants where high safety, ATEX approval and reliable operation are required.
- The DAPS pneumatic rotary actuator is a double-acting rotary actuator with a swivel angle of 92°.
- It is characterised by its robust design with flange hole patterns in accordance with ISO 5211 and precise shaft connections (T17–T27).
- Thanks to its ATEX approval (gas: II 2G, dust: II 2D) and temperature resistance from -50 °C to +60 °C, the actuator is also suitable for use in potentially explosive areas and demanding environments.
- With an operating pressure range of 3 to 8.4 bar and different sizes, it offers versatile application possibilities in process and automation technology.
