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 .
2. Switch off the compressed air supply.
3. Remove the cover of the stop bolt
2 and sealing disc 3 .
4. Loosen the stop nut 5 together with the sealing disc 6 .
5. To reduce the rotation angle, screw in the stop adjusting screw 4 .
To increase the rotation angle, unscrew the stop adjusting screw 4 .
6. Tighten the stop nut 5 . Make sure that the sealing disc 6 is centred on the
stop nut and lies in the recess of the flange.
7. Switch on the compressed air supply.
8. To check the adjustment, run through a complete cycle.
9. Put the cover of the stop bolt
2 and sealing disc 3 into place again.
8.4 Adjusting the end position – “Valve open” position
The “Valve open” position is set using the adjusting screw on the end flange of
the gear unit.

9 Operation
• Comply with operating conditions.
• Observe the permitted limit values.
NOTICE!
For continuous operation under extreme conditions: Use lubricated compressed
air. The oil must be chemically inert and must not carbonise. Once the product has
been used with lubricated compressed air, it must continue to be operated with
lubricated compressed air only.
