Product Description
- The Festo DAPS series single-acting rotary actuator is ideal for applications in potentially explosive atmospheres where reliable reset of the valve in the event of a fault must be guaranteed.
- Typical areas of application are the chemical and petrochemical industries, water and wastewater technology, and process engineering plants.
- Thanks to its ATEX approval, high corrosion resistance (KBK 3) and operating temperature range down to -50 °C, the DAPS-2880 is ideal for outdoor use and extreme industrial environments.
- The Festo DAPS-2880 rotary actuator is a powerful, single-acting pneumatic actuator with yoke kinematics for precise control of rotary movements up to 90°.
- It has a return spring that ensures defined end positions – even in the event of pressure loss.
- Thanks to its compact design, high efficiency and suitability for ATEX zones (II 2G/2D), the actuator meets the highest safety standards and is designed for demanding industrial environments.
- It is standardised in accordance with ISO 5211 and NAMUR (VDI/VDE 3845) and meets SIL 2 Low Demand requirements.
