1.1Markingofsafetyinstrucons
1.2 Safety fundamentals
The installaon, assembly, commissioning, maintenance and any other work on pneumac actuators must be
performed by qualied personnel.
This manual is part of the device and must be available for the operang personnel at all mes. This manual must
be read and understood before operaon.
The device may only be operated in perfect condion. No safety devices are removed or deacvated. A rebuilding
or modicaon of the device is strictly prohibited.
1.3 Transport, storage and packaging
The devices must be carefully handled, transported and stored.
The devices should be transported to the end desnaon in their original packaging and unpacked immediately
before installaon.
The actuators are to be stored in a clean, dry storage, which is neither exposed to excessive vibraon nor to rapid
temperature changes.
Prevent ingress of dirt or moisture into the actuator. Close or ghten both air connecons.
Proper disposal of packaging is the customer´s responsibility.

• Type code
2.1Designdescripon
Pneumac actuators of the PRY series are designed for the automaon of rotary valves with a 90° rotaon angle.
They have a modular structure and, depending on the applicaon, consist of one or two pneumac modules, a
center module, a spring module and an oponal module for manual actuaon. In the single-acng version, the spring
module ensures closing or opening in the event of a control media failure (spring-closing or spring-opening).
Two characterisc torque proles are available for generang a drive torque that is adapted to the valve torque.
These are created using either a symmetrical or a canted yoke.
The PRY actuator series oers a torque range of 1000 – 250.000 Nm (double-acng) and 300 – 150.000 Nm (single-
acng). The standard version of the actuators provides valve mounng interfaces according to ISO 5211 and an
accessory interface according to VDI/VDE 3845.
The maximum operang pressure of the pneumac Scotch-Yoke actuators of the PRY series is between 3 and 10 bar
depending on size and conguraon. The maximum operang pressure is specied on the typelabel of the respecve
actuator.

2.2 Intended use
Actuators of the PYR series are primarily used for the automaon of quarter-turn valves such as ball valves, buery
valves or plug valves, but can also be used for other applicaons. Contact our qualied personnel where required.
The specied operang and liming values for temperature, pressure, control medium, etc. must be observed.In
operaon of valves high kinec energies may arise, which are transmied to the actuator. Make sure that the drive
is protected from damage by complying with the minimum travel mes safely. Control speed can be reduced by the
use of throle valves, which can be purchased from our sales department.
For valve types with high ywheel mass and low torque requirements the operang condions of the actuator must
be coordinated with us in advance.
The actuator may only be used:
• in perfect condion
• as spulated
• safety- and danger-conscious in consideraon of the operang instrucons
• if all safety devices are in place and funconing

3.2Installaoninstrucons
1. Ensure that the pneumac module is completely depressurized by venng it into the atmosphere and discon-
necng all power sources from the accessories.
2. Make sure that the valve and the actuator are aligned in the same posion (i.e. valve closed - actuator in the
closed posion or both open). In the case of actuators with spring return, align the valve to the safe posion of
the actuator. If a manual override is used, it must also be ensured that it corresponds to the valve and actuator
posion.
3. Posion the valve, aach the mounng bracket and then mount the coupling sha on the valve sha (when
using a mounng kit). Check the posion of the actuator and valve, align the valve sha (or sha coupling)
with the actuator sha and slide the actuator onto the mounng surface of the mounng bracket (or onto the
ISO ange of the valve if no mounng bracket is used).
4. When using an emergency manual gearbox between actuator and valve, the gearbox must rst be aached
and fastened to the valve according to the prescribed procedure. Then turn back the stop screws on the gear-
box. Mount the actuator with the coupling sha on the gearbox and x the actuator on the gearbox ange.
5. To align the screw holes, the valve mounng screws on the mounng bracket may need to be loosened slightly.
The actuator xing screws should be easy to screw into the threaded holes of the actuator interface without
the mounng bracket (or the ISO ange of the valve) being loaded by transverse forces. If necessary, turn the
drive a lile and/or adjust the adjusng screws of the drive. Fasten the actuator to the mounng bracket/on
the gearbox ange/on the head ange of the valve.
6. Before operang the actuator, the manual override (if available) must be disengaged.
7. Adjust the adjusng screws of the quarter turn actuator correctly for open and closed valve posions according
to the recommendaons of the valve manufacturer. The adjusng screws of the quarter turn actuator should
dene the end stops, not that of the gearbox.
8. Tighten the lock nuts on the stop screws aer adjusng the stop screws. Make sure that the screws on the
gearbox (if present) are now set and locked so that they are slightly behind the end posion of the drive.
9. Make sure that the manual actuaon modules are unlocked before you start up the actuator.
10.Pneumacally operate the actuator several mes to check that it is operang correctly and smoothly. If the
actuator is equipped with a switch box or other accessories, set it now.

3.3Sengtheendposions
Sengtheendposionclockwise(CW):
1. Turn the actuator clockwise unl it reaches the end
stop and check the seng.
2. Loosen lock nut "X"
3. Vent the actuator and turn the adjusng screw
in the desired direcon (unscrewing expands the
swivel angle, screwing in reduces the swivel angle)
4. Vent the actuator and check the seng again.
5. Repeat the seng procedure (steps 2 to 4) if
necessary.
6. Tighten the lock nut again.
Sengtheendposioncounterclockwise(CCW):
1. Turn the actuator counterclockwise unl it reaches
the end stop and check the seng.
2. Loosen lock nut "Y"
3. Vent the actuator and turn the adjusng screw
in the desired direcon (unscrewing expands the
swivel angle, screwing in reduces the swivel angle)
4. Vent the actuator and check the seng again.
5. Repeat the seng procedure (steps 2 to 4) if
necessary.
6. Tighten the lock nut again.
Stop screws
By adjusng the stop screws, both end
posions can be adjusted by +/- 6° for
ne adjustment of the valve end posi-
on. The respecve seng posion is
secured by ghtening the lock nut.
