Product Description
- The Festo DAPS series single-acting rotary actuator is ideal for applications in the chemical, water, power plant and process industries, for example.
- Thanks to its ATEX approval, wide temperature range and high corrosion resistance, the rotary actuator can also be used in extreme environmental conditions and potentially explosive areas.
- The Festo DAPS-1440 is a single-acting pneumatic rotary actuator with yoke kinematics, which ensures reliable end position return in the event of pressure loss via an integrated return spring.
- Its robust design, T46 shaft connection, G3/8 pneumatic connections and standard flange connection in accordance with ISO 5211 make it the ideal choice for demanding industrial applications.
- The actuator complies with ATEX guidelines and is approved for use in safety-related control chains up to SIL 2.
