In these Operating and Installation Instructions dangers, risks and items of safety
information are highlighted to attract special attention.
Information marked with the above symbol and “ATTENTION ! ” describe practices, a
failure to comply with which can result in serious injury or danger of death for users or third
parties or in material damage to the system or the environment. It is vital to comply with
these practices and to monitor compliance.
All other information not specifically emphasised such as transport, installation, operating
and maintenance instructions as well as technical data (in the operating instructions,

Operating and installation instructions
Thrust actuator ARI-PREMIO
4.0 Description
4.1 Field of application
ARI-PREMIO linear thrust actuators are employed to actuate control or shut-off valves
requiring a nominal linear stroke distance of up to 80 mm and thrust from 2.2 kN to 15 kN.
The thrust actuators are set to the thrust forces specified in the technical data. If supplied
with the valve, the lift of the thrust actuator will be set to the stroke distance of the valve.
Selection of the proper actuator version in alignment with the corresponding fitting as well
as use of the thrust actuator in accordance with the specified technical data is the
responsibility of the systems engineer.
See data sheet for areas of application, application limits and potential.
Any use of the thrust actuator beyond the specified technical data or improper use of the
actuator is deemed to be not for the intended purpose.
The ambient conditions have to be conform to the actual electromagnetic compatibility
directives. Additional the compatibility to this directives has to be maintained in case of
expansion or other changing of the ambient conditions.
4.2 Method of functioning
The thrust actuator, fitted with a yoke or columns, is mounted to the valve.
Transfer of force is effected via a coupling safeguarded against torsion.
The torsion safeguarding feature also serves as a lift indicator.
The lift settings can be read off on a lift dial attached to the yoke or between the 2-ear
clamps mounted to the column.
The electrical components are accommodated separately from the gearbox underneath a
sealed hood, thus being protected against operating and environmental effects.
Following removal of the hood, easy access is provided to the switchgear and indicating
feature.
The rotary motion of the motor is transmitted to the spindle nut by means of spur gear.
The drive spindle, which is safeguarded against torsion, screws its way into the spindle nut
and thus performs a pull or push motion depending on the sense of rotation.
In the final positions of the valve, the spindle nut is pressed against a set of springs so as to
produce closing force.
The motor is switched off by means of two load-dependent switches and one stroke-
dependent switch. The load-dependent switches will also switch off the motor if foreign
bodies have lodged themselves between the valve seat and cone.
The load-dependent switches serve to protect the valve and thrust actuator against
damage.

5.0 Installation
5.1 General installation data
- In addition to general installation guidelines, the following points are required to be
observed:
- Planners / construction firms and operators are responsible for positioning and installing
the products.
Where relay points and electronic load relays are particularly sensitive a coil should be
connected in series additionally to each relay point.
- Contactors of 16A and upwards do not need a safety circuit.
- Check thrust actuator for damage prior to fitting.
Damaged parts must be replaced by original spares.
- Existing operating instructions for valve.
- Complete valve with crossarm.
- Valve cone approximately in mid lift position - on no account supported inside a seat!
- Electrical installation in accordance with current regional regulations.
- Conductor cross-section selected to correspond to the given drive power and existing line
length.
ATTENTION !
- Work on electrical systems or equipment must only be carried out by qualified
electricians or by trained individuals under the guidance and supervision of a
qualified electrician in compliance with regional electrical safety requirements
and regulations.
- Valve mountings such as drives, handwheels, hoods must not be used to take
external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
Non-compliance may lead to death, injury or damage to property due to
persons falling or parts being dropped.
- Actuator components which rotate or move during operation are coloured red.
Crushing and injury hazard!
ATTENTION !
- A voltage is induced in the thrust actuator motor. This induction voltage may be
higher than the operating voltage.
- For this reason relays and electronic load relays for thrust actuator control
require a protective circuit. The contacts of unprotected relays may stick after a
while.
- This may result in reversed directions of rotation or defective switch-off
Recommended safety circuit for relays and electronic load relays:
Connect a varistor or RC module parallel to each relay point.
Varistor S10K385 to S10K460
RC module 100 Ohm / 100nF
Recommended coil:
Toroidal coil 2mH / 2A

Operating and installation instructions
Thrust actuator ARI-PREMIO
- Mains fuse rating max. 6A.
- Circuit breakers in the plant to cut off the mains supply to the actuator.
- Conformity of technical data on thrust actuator with field conditions.
- Mains voltage in accordance with data specified on rating plate of thrust actuator.
- Thrust actuator complete with yoke or distance columns and coupling parts intended for
mounting to the corresponding valve.
- Ease of access to installation site.
- Adequate clearance space above the thrust actuator for removing the hood
(refer to point 4.5 Dimensions).
- Install where there is protection against high-energy heat radiation.
- The ambient temperature must be between -20°C and +70°C.
If installed outdoors, the thrust actuator must be provided with an additional cover to protect
against
- rain,
- direct insulation,
- dust.
In case of widely fluctuating ambient temperatures, high atmospheric humidity and
temperatures below the freezing point, your are recommended to install a heating resistor
to minimise condensation buildup in the actuator.
- Thrust actuator mountable in any position except in downward suspended position.
If installed with a horizontal connecting rod, the thrust actuator must be mounted so both
yoke legs or columns are on top of one another in the vertical plane (see Fig. 4 ).

5.2 Manual operation
5.2.1 ARI-PREMIO 2.2 - 5 kN
With the motor in the stationary state, the thrust actuator can be run in the retracted and
extended state with the handwheel firmly meshed with the gear.
Proceed as follows:
- Swing out lever (pos. 50.12.1) from handwheel (pos. 50.12).
- Turning in clockwise direction --> extending spindle.
- Turning in counter-clockwise direction --> retracting spindle.
Fig. 5
ATTENTION !
- The handwheel always rotates during motor-driven operation (running
indicator). Never activate manual operation while the motor is running.
Injury hazard!
- In the manual operating mode pay careful attention in the final positions that the
handwheel is only turned to the point where the torque switch trips (audible
click) as otherwise damage will be caused to the thrust actuator! Since the
handwheel always follows during motor-driven operation (running indication),
never operate by hand while the motor is running - potential injury hazards!

Thrust actuator ARI-PREMIO
5.2.2 ARI-PREMIO 12 - 15 kN
With the motor in the stationary state, the thrust actuator can be run in the retracted and
extended state with the engageable handwheel.
Proceed as follows:
- Fold the turning handle out of the handwheel (A)
- Turn the handwheel slightly and push in the engaging button for manual mode (B)
--> the button engages
- Turning in clockwise direction --> extending spindle
- Turning in counter-clockwise direction --> retracting spindle
The motor is no longer in mesh when the handwheel is engaged. The handwheel is
automatically disengaged when the motor starts and the motor is once more in mesh.
Fig. 6
ATTENTION !
- Do not attempt to engage manual operation until the motor has stopped.
Switching over while the motor is running may damage the thrust actuator.
- In the manual operating mode pay careful attention in the final positions that the
handwheel is only turned to the point where the torque switch trips (audible
click) as otherwise damage will be caused to the thrust actuator!
ATTENTION !
When changing the motor, it’s necessary to
observe for a correct function of the manual
operating device, that the head-cap screw
M4x18 is screwed in the right place.

5.3 Installation instructions for mounting to valves
5.3.1 Mounting for valve-lift up to 30 mm (yoke version)
Fig. 7
To mount the thrust actuator to a valve having a nominal lift of up to 30mm, proceed
as follows:
- Screw coupling (pos. 50.27) out of torsion safety feature (pos. 50.32) of thrust
actuator (not illustrated).
- Position valve cone approximately in mid lift position.
Fig. A: - Turn flat hexagon nut if not present on valve spindle.
Fig. A-B: - Slip coupling (pos. 50.27) over valve spindle.
- Screw threaded bush (pos. 50.87) matching the valve onto the valve spindle in
accordance with setting dimension (Y) and lock with hexagon nut.
- Setting dimension (Y) for fitting-projection (X) 60 and 83mm = 102mm.
Fig. C: - Place thrust actuator (pos. 50) on valve.
- Mount thrust actuator (pos. 50) on fitting with two T-head bolts (pos. 50.19), two
washers (pos. 50.20), two spring washers (pos. 50.21), two hexagon nuts
(pos. 50.22).
Fig. D/E: - Swing out handwheel lever (pos. 50.12.1) and use it to move out the thrust
actuator until the driving spindle (pos. 50.30) comes to rest on the threaded
bush (pos. 50.87).
ATTENTION !
Setting dimension (Y) and fitting-projection (X) are measured with
inserted valve spindle. This means for
- 2-way valves at closed valve,
- 3-way valves with mixing plug at closed way B,

5.3.2 Mounting for valve lift over 30 mm to 80 mm (column version)
Fig. 8
To mount the thrust actuator to a valve having a nominal lift of over 30mm to 50mm,
proceed as follows:
- Screw coupling (pos. 50.27) out of torsion safety feature (pos. 50.32) of thrust
actuator
(not illustrated).
- Position valve cone approximately in mid lift position.
Fig. A: - Turn flat hexagon nut if not present on valve spindle.
Fig. A-B: - Slip coupling (pos. 50.27) over valve spindle.
- Screw threaded bush (pos. 50.87) matching the valve onto the valve spindle in
accordance with setting dimension (Y) and lock with hexagon nut.
- Setting dimension (Y) for fitting-projection (X) 83mm = 102mm.
- Setting dimension (Y) for fitting-projection (X) 98mm = 116mm.
ATTENTION !
Setting dimension (Y) and fitting-projection (X) are measured with
inserted valve spindle. This means for
- 2-way valves at closed valve,
- 3-way valves with mixing plug at closed way B,
- 3-way valves with diverting plug at closed way A
After measuring put the valve plug back in the mid lift position!

Fig. C: - Slip 2-ear clamp (pos. 50.26) onto a distance column (pos. 50.24) press on
very lightly.
- Screw distance column with 2-ear clamps on opposite side of handwheel into
the flange in such a way that one of the 2-ear clamps is situated above the
torsion safety feature (pos. 50.32) and the other below.
- Screw the other distance column into the flange likewise.
- Place thrust actuator (pos. 50) with distance columns onto valve and fix into
position with two self-locking hexagon nuts (pos. 50.25).
Fig. D/E: - Fold out turning handle of handwheel (pos. 50.12.1), slightly turn the
handwheel and press in the engaging button for manual mode (only 12 - 15 kN)
(button engages). Having done this, move out the thrust actuator until driving
spindle (pos. 50.30) comes into contact with threaded bush (pos. 50.87).
Fig. F: - Screw coupling (pos. 50.27) firmly into torsion safety feature (pos. 50.32) and
secure using grub screw M6 (pos. 50.35).
- Move the valve to the lowest position.
- Press 2-ear clamps (pos. 50.26) into position according to the stroke so they
cannot slip, with the bottom clamp in the lowest valve position located directly
below torsion safety feature (pos. 50.32) and the top clamp in the highest valve
position located directly above the torsion safety feature.
- Move the valve to both travel positions and check that it reaches them reliably.
- Fold turning handle of handwheel (pos. 50.12.1) back in.
- Make the electrical connection (see point “5.4 Electrical connection”). The
engaging button for manual mode (only 12 - 15 kN) disengages when the
motor starts up.
- Set standard travel switch S3 (see point 5.5.3.2).
