DFPD-HD, the heavy-duty quarter turn actuator from Festo is flexible, powerful, robust, and offers exceptionally reliable control of high-volume media flows that include water and wastewater, among others.
Designed in accordance with the scotch-yoke principle and with three available solutions with torque ratings of 9,000, 18,000, and 32,000 Nm, it is also ideal for the automation of large ball valves, butterfly valves, and air dampers.
The DFPD-HD can also be used at any temperature ranging from -20 to 80 degrees Celsius, and its spring forces can be adapted for various applications by configuring the multiple spring cartridges. In the event of a power breakdown, the mechanical or hydraulic manual that provides additional safety also allows the DFPD-HD to be operated manually.
