Heavy-duty quarter turn actuator DFPD-HDFesto’s quarter-turn actuator DFPD-HD system offers powerful solutions for various applications in process automation. Available in three versions of max. 9,000, 18,000 and 32,000 Nm respectively, the quarter-turn actuator DFPD-HD fits flexibly to applications. The single actuator’s standard clockwise rotating direction provides a high level of safety by ensuring that the media flow is interrupted automatically in case of a malfunction. Rotating direction can also be configured in anticlockwise, in which case the DFPD-HD will release the media flow if a malfunction occurs. This new DFPD-HD is also available in a double-acting version for even greater flexibility. This quarter-turn actuator can be used in applications, where the Safety Integrity Level up to SIL3 is required. The DFPD-HD can be used  at any ambient temperature between -20 and 80°C. Its spring force can be adapted for different applications by configuring various spring cartridges. A mechanical or hydraulic manual override provides additional safety. This allows the actuators to be operated manually in the case of a power breakdown.
