Quarter turn actuator DFPD Flexible in use! Highlights • Single-acting or doubleacting • Very compact • Highly modular • End position adjustable at both ends • Optimised spring setting design • For extreme temperatures: -50 … +150 °C • Mounting plate for pilot valve in EU (G) and US version (NPT) DFPD is the new benchmark for quarter turn actuators. It can be used as an individual actuator or as part of a complete automated process valve system from Festo. With a torque range from 10 to 2.300 Nm, a rotation angle up to 180° and corrosion-resistant versions, the single- or double-acting DFPD is suitable for ball valves, butterfly valves or air dampers in the chemical, pharmaceutical and beverage industries, as well as for water treatment. Compact and modular The compact rack-and-pinion combination – especially in the single-acting version – is easy to install even when space is at a premium. Its range of variants, the standardised hole patterns to NAMUR VDI/VDE 3845 for pilot valves as well as the many compatible peripheral devices mean that it can be operated in a large variety of applications. In addition, both the end stop positions can be adjusted and the direction of rotation of the singleand double-acting DFPD can be selected. Optimised spring cartridge design for simple torque adaptation Thanks to the spring design the pressure range can be optimally set for the task in hand. This allows pressures from 2 to 6 bar to be easily set in steps of 0.5 bar. For large temperature ranges The DFPD operates reliably at extreme temperatures, with the breadth of low and highemperature versions ranging from -50 … +1

Quarter turn actuator DFPD Completely automated process valves from a single supplier When combined with a sensor box, a pilot valve or a positioner, the quarter turn actuator DFPD can be expanded into a complete automated process valve system.
