– Observe labelling on the product.
– Prior to mounting, installation and maintenance work: Switch off compressed
air supply and secure it from being switched back on.
– Exhaust drive prior to assembly, installation and dismounting.
Operating medium
– Use compressed air only in accordance with the specifications
è14 Technical data.
– Use only unlubricated compressed air under normal conditions. Once the
product has been used with lubricated compressed air, it must continue to be
operated with lubricated compressed air only.
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 the handling of hazardous substances
and the transport of dangerous goods.
2.2 Intended use
The product is intended to actuate process valves, such as ball valves and butter-
fly valves, with a rotation angle from 0° (valve closed) to 90°. The product is suit-
able for control of media-flow process valves in fluid engineering systems.
NOTICE!
The operating torque of the drive must not be greater than the maximum permiss-
ible torque listed in ISO5211 in relation to the size of the mounting flange and of
the coupling.
2.3 Training of qualified personnel
Installation, commissioning, maintenance and disassembly should only be con-
ducted by qualified personnel.

5.2 Function
Fig. 2 Symbol - single-acting semi-rotary drive
The DFPD-HD-...-...S... is a single-acting semi-rotary drive. The piston is moved by
pressurising the pneumatic cylinder. The semi-rotary drive of type
DFPD-HD -...- RS closes clockwise, the type DFPD-HD -...- LScloses anti-clockwise.
The linear motion of the piston is converted into a swivel motion of the transmis-
sion shaft by a Scotch yoke system (Scotch-Yoke). The spring force returns the
process valve. The connected process valve records the reaction torque of the
semi-rotary drive.

6 Transport and storage
WARNING!
Danger of crushing.
Body parts can be crushed if the product falls.
• Use appropriate load handling equipment.
• Lift the semi-rotary drive using the transport lugs.
• Before transporting: detach the semi-rotary drive from the process valve.
NOTICE!
For variants with a hydraulic unit (DFPD-HD-...-HP): environmental damage due to
escaping oil.
• Store the product horizontally and avoid inclines.
– When dispatching used products: comply with all legal requirements for the
handling of hazardous substances and the transport of dangerous goods. For
return to Festo è 2.1 General safety instructions.
– Remove all attachments.
– Store the product in a cool, dry, UV-protected and corrosion-protected envir-
onment. Ensure that storage times are kept to a minimum.
– For long-term storage: test the function of the product regularly.
– Observe environmental and storage conditions è 14 Technical data.
– Seal pneumatic connections.
– Protect coupling parts with grease or protective oil.
– To prevent damage to the coupling flange, store the product on a level
wooden pallet.
7 Mounting and installation
NOTICE!
Semi-rotary drives of the series DFPD-HD are intended for installation parallel to
the line axis.
• If another installation position is necessary, consult your regional Festo con-
tact èwww.festo.com.
NOTICE!
Semi-rotary drives with a hydraulic manual override are designed for a horizontal
installation position only. In this position, the pump and reservoir are mounted
towards the top of the hydraulic cylinder.
7.1 Assembly
1. Clean the coupling flange.
2. Adjust the valve position according to the semi-rotary drive settings.
3. Lubricate the valve spindle.
4. Place the semi-rotary drive on the control shaft of the process valve.
5. Mount the semi-rotary drive on the connecting flange of the process valve
with 8 threaded pins.

7.2 Pneumatic installation
• Observe the operating instructions of the process valve.
• Test the correct function of the pneumatic control.
• Take precautions at the open port 4, which prevent the suction of harmful
substances, e.g.unfiltered outside air, humidity or water, into the product.

8.2 Commissioning the semi-rotary drive
1. Check operating conditions and critical limits è 14 Technical data.
2. Switch on the compressed air supply.
3. Check the semi-rotary drive for leakage.
4. First check the direction of rotation of the semi-rotary drive and reaction of
the process valve at a low travel speed.
