2.1Designdescripon
Pneumac actuators of the PRY series are designed for the automaon of rotary valves with a 90° rotaon angle.
They have a modular structure and, depending on the applicaon, consist of one or two pneumac modules, a
center module, a spring module and an oponal module for manual actuaon. In the single-acng version, the spring
module ensures closing or opening in the event of a control media failure (spring-closing or spring-opening).
Two characterisc torque proles are available for generang 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 oers a torque range of 1000 – 250.000 Nm (double-acng) and 300 – 150.000 Nm (single-
acng). The standard version of the actuators provides valve mounng interfaces according to ISO 5211 and an
accessory interface according to VDI/VDE 3845.
The maximum operang pressure of the pneumac Scotch-Yoke actuators of the PRY series is between 3 and 10 bar
depending on size and conguraon. The maximum operang pressure is specied on the typelabel of the respecve
actuator.

2.2 Intended use
Actuators of the PYR series are primarily used for the automaon of quarter-turn valves such as ball valves, buery
valves or plug valves, but can also be used for other applicaons. Contact our qualied personnel where required.
The specied operang and liming values for temperature, pressure, control medium, etc. must be observed.In
operaon of valves high kinec energies may arise, which are transmied 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 throle valves, which can be purchased from our sales department.
For valve types with high ywheel mass and low torque requirements the operang condions of the actuator must
be coordinated with us in advance.
The actuator may only be used:
• in perfect condion
• as spulated
• safety- and danger-conscious in consideraon of the operang instrucons
• if all safety devices are in place and funconing
Anyusenotpre-approvedbythemanufacturerisconsideredimproper!

3.2Installaoninstrucons
1. Ensure that the pneumac module is completely depressurized by venng it into the atmosphere and discon-
necng all power sources from the accessories.
2. Make sure that the valve and the actuator are aligned in the same posion (i.e. valve closed - actuator in the
closed posion or both open). In the case of actuators with spring return, align the valve to the safe posion of
the actuator. If a manual override is used, it must also be ensured that it corresponds to the valve and actuator
posion.
3. Posion the valve, aach the mounng bracket and then mount the coupling sha on the valve sha (when
using a mounng kit). Check the posion of the actuator and valve, align the valve sha (or sha coupling)
with the actuator sha and slide the actuator onto the mounng surface of the mounng bracket (or onto the
ISO ange of the valve if no mounng bracket is used).
4. When using an emergency manual gearbox between actuator and valve, the gearbox must rst be aached
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 mounng screws on the mounng 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 mounng bracket (or the ISO ange of the valve) being loaded by transverse forces. If necessary, turn the
drive a lile and/or adjust the adjusng screws of the drive. Fasten the actuator to the mounng bracket/on
the gearbox ange/on the head ange of the valve.
6. Before operang the actuator, the manual override (if available) must be disengaged.
7. Adjust the adjusng screws of the quarter turn actuator correctly for open and closed valve posions according
to the recommendaons of the valve manufacturer. The adjusng screws of the quarter turn actuator should
dene the end stops, not that of the gearbox.
8. Tighten the lock nuts on the stop screws aer adjusng 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 posion of the drive.
9. Make sure that the manual actuaon modules are unlocked before you start up the actuator.
10.Pneumacally operate the actuator several mes to check that it is operang correctly and smoothly. If the
actuator is equipped with a switch box or other accessories, set it now.

3.3Sengtheendposions
Sengtheendposionclockwise(CW):
1. Turn the actuator clockwise unl it reaches the end
stop and check the seng.
2. Loosen lock nut "X"
3. Vent the actuator and turn the adjusng screw
in the desired direcon (unscrewing expands the
swivel angle, screwing in reduces the swivel angle)
4. Vent the actuator and check the seng again.
5. Repeat the seng procedure (steps 2 to 4) if
necessary.
6. Tighten the lock nut again.
Sengtheendposioncounterclockwise(CCW):
1. Turn the actuator counterclockwise unl it reaches
the end stop and check the seng.
2. Loosen lock nut "Y"
3. Vent the actuator and turn the adjusng screw
in the desired direcon (unscrewing expands the
swivel angle, screwing in reduces the swivel angle)
4. Vent the actuator and check the seng again.
5. Repeat the seng procedure (steps 2 to 4) if
necessary.
6. Tighten the lock nut again.
Stop screws
By adjusng the stop screws, both end
posions can be adjusted by +/- 6° for
ne adjustment of the valve end posi-
on. The respecve seng posion is
secured by ghtening the lock nut.
