2 Safety
 Take into consideration the legal regulations for the respective destination.
 Observe product labelling.
 Before carrying out mounting, dismantling, installation and maintenance work,
switch off the compressed air supply and vent the drive. Secure compressed air
supply against accidental restarting.
Return to Festo
Hazardous substances can endanger the health and safety of personnel and cause
damage to the environment. To prevent hazards, the product should only be
returned upon explicit request by Festo.
 Consult your regional Festo contact.
 Complete the declaration of contamination and attach it to the outside of the
packaging.
 Comply with all legal requirements for handling hazardous substances and
transporting dangerous goods.
3 Use for intended purpose
The DFPD-HD quarter turn actuator is intended to activate process valves, such as
ball valves and butterfly shut-off valves with a rotation angle from 0° (valve closed)
to 90°. The quarter turn actuator is suitable for controlling media-flow process
valves in fluid engineering systems.
 The product may only be used in its original status without unauthorized
modifications.
 Only use the product if it is in perfect technical condition.
 Observe the specifications on the product labelling.
Note
The operating torque of the drive must not be higher than the maximum
permissible torque listed in ISO 5211, with reference to the size of the mounting
flange and of the coupling.
Operating medium
 Only use compressed air in accordance with the specifications
èTechnicaldata.
 Only use unlubricated compressed air under normal conditions. Once the
product has been used with lubricated compressed air, it must continue to be
operated with compressed air only.

6 Product overview
The product label can be found on the gear unit.
6.1 Function
The DFPD-HD-...-...S... is a single-acting quarter turn actuator.
The piston is moved by pressurising the pneumatic cylinder.
In the case of type DFPD-HD-...-RS, the quarter turn actuator is put in the “Valve
open” position, while type DFPD-HD-...-LS is put in the “Valve closed” position.
The linear motion of the piston is transformed using
aScotch yoke system into a swivel motion of the
transmission shaft. The return of the process valve is
implemented by spring force.
The connected process valve records the moment of reaction of the quarter turn
actuator.
Fig. 2 shows the mode of operation on the example of the DFPD-HD-...-RS:

7 Transport and storage
Warning
Danger of crushing!
The product without accessories weighs up to about 1500 kg, depending on the
product version.
Body parts can be crushed if the product falls.
 Use appropriate load handling equipment.
 Use the 3 transport lugs to life the quarter turn actuator (Fig. 3, 8).
 Loosen the quarter turn actuator before transporting the process valve.
Note
For variants with a hydraulic unit (DFPD-HD-...-HW): environmental damage due
to escaping oil.
 Store the product horizontally and avoid inclines.
 Observe environmental and storage conditions èTechnical data.
 To prevent contamination, close any pneumatic connections.
 Protect the coupling parts with grease or protective oil.
 To prevent damage to the coupling flange, store the quarter turn actuator on an
even wooden pallet.
 Store the product in a cool, dry, UV- and corrosion-protected environment.
 In case of long-term storage: regularly check the function of the quarter turn
actuator.
 When shipping used products: comply with all legal requirements for handling
hazardous substances and transporting dangerous goods.

8 Mounting and installation
Note
Installation should only be conducted by qualified specialized personnel.
Note
Quarter turn actuators of the series DFPD-HD are intended for installation in
parallel with the line axis.
 If another mounting position is necessary, consult your regional Festo contact
èwww.festo.com.
Note
Quarter turn actuators with a hydraulic manual override are designed for a
horizontal mounting position only. In this position, the pump and reservoir as
mounted towards the top of the hydraulic cylinder.
8.1 Mounting
1. Clean the coupling flange.
2. Adjust the valve position according to the quarter turn actuator settings.
3. Lubricate the valve stem.
4. Place the quarter turn actuator on the switching shaft of the process valve.
5. Fasten the quarter turn actuator to the connecting flange of the process valve
with 8 threaded pins.

9 Commissioning
Note
Commissioning should only be carried out by qualified personnel.
Prerequisites
– The drive is fully mounted and connected.
1. Check operating conditions and limit values èTechnical data.
2. Switch on the compressed air supply.
3. Check the quarter turn actuator for leakage.
4. First check the direction of rotation of the quarter turn actuator and reaction of
the process valve at a low travel speed.
9.1 Adjusting the end position – on the end flange of the pneumatic cylinder
The end position is adjusted using the adjusting screw on the end flange of the
pneumatic cylinder:

1. To relieve the stop bolt, pressurise the port (2) slightly.
2. Remove the cover of the stop bolt 1and sealing disc 2.
3. Loosen the stop nut 4together with the sealing disc 5.
4. To reduce the rotation angle, screw in the stop adjusting screw 3.
To increase the rotation angle, unscrew the stop adjusting screw 3.
5. Tighten the stop nut 4. Make sure that the sealing disc 5is centred on the
stop nut and lies in the recess of the flange.
6. To check the adjustment, run through a complete cycle.
7. Put the cover of the stop bolt 1and sealing disc 2into place again.

9.2 Adjusting the end position – on the spring package
