packaging.
– Comply with all legal requirements for the handling of hazardous substances
and the transport of dangerous goods.
2.2 Intended use
The semi-rotary drive DFPD-HR is intended to actuate process valves, such as ball
valves and butterfly valves, with a rotation angle from 0° (valve closed) to 90°.
The semi-rotary drive is suitable 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 skilled personnel
Installation, commissioning, maintenance and disassembly should only be con-
ducted by qualified personnel.

5.2 Function
Fig. 2
The DFPD-HD-...-RD is a double-acting semi-rotary drive. The piston is moved by
pressurizing and exhausting the pneumatic cylinder.
The linear motion of the piston is transformed using a Scotch yoke system into a
swivel motion of the transmission shaft. 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-...-HW): 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.
– Store the product in a cool, dry, UV-protected and corrosion-protected envir-
onment. Ensure that storage times are kept to a minimum.
– In case of long-term storage: regularly check the function of the semi-rotary
drive.
– Observe environmental and storage conditions è 14 Technical 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 semi-rotary drive on a
level wooden pallet.
7 Assembly 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 stem.
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
using 8 threaded pins.
6. Tighten the nuts of the threaded pin crosswise.

8 Commissioning
8.1 Requirements
– The drive is fully mounted and connected.
8.2 Commissioning the semi-rotary drive
1. Check operating conditions and limit values 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.
8.3 Adjusting the end position – “Valve closed” position
The “Valve closed” position is set using the adjusting screw on the end flange of
the pneumatic cylinder.
Fig. 4
1. Set the semi-rotary drive to the “Valve closed” position1.
