ApplicationsAUMA GSI part-turn gearboxes are used in nuclear

power plants for the automation of part-turn valves. For

this purpose they are combined with an AUMA SAN or SAI

actuator or with any other multi-turn actuator which has

been qualified accordingly. Part-turn valves include, for

example, butterfly valves or ball valves.

The gearboxes are certified according to

IEEE 382-1996. They are qualified for use in outside

and inside containment applications.

Due to their wide torque range, their modular design

and potential for use with electric multi-turn actuators, the

gearboxes can be used for the most varied applications.

This brochure will provide both the beginner and the

expert with an overview of the functions and applications

of AUMA GSI part-turn gearboxes. It can be used as the

basis to determine whether a device is suitable for the

chosen application.

For detailed product selection refer to the separate data

sheets, dimension sheets and price lists. The quotation

specialists in our Muellheim headquarters can help you

find the correct device for the application.

Since the mid-1970s, AUMA has been producing

devices for the use in nuclear power plants which have

provided long-term operational reliability in this field.

GSI part-turn gearboxes are based on the GS part-turn

gearbox whose first generation was introduced to the

market as early as 1967. Ever since the gearboxes have

been continuously improved; two features, however,

remain unchanged:

■ a simple and robust design principle

■ high end stop strength.

A long lifetime with very low maintenance, even under

high loads, are the benefits of this sophisticated gearbox

range.

The latest detailed information on the GSI part-turn

gearboxes can be found on the Internet under

www.auma.com. All documents, including dimensional

drawings, and final inspection records for supplied gear-

boxes are available on the Internet in digital form.

Modular design/versions

Modular concept – different applicationsValves in nuclear power plants are used in areas with dif-

ferent safety relevance (outside containment and inside con-

tainment), but also in conventional areas. They are available

in many designs and different sizes. Butterfly valves, ball

valves or dampers with diameters ranging from a few centi-

metres to several metres are to be opened or closed and

controlled electrically.

AUMA meets the various requirements with their modular

product range. GS and GSI part-turn gearboxes are central

elements of this product range. The GS range is suitable for

use in conventional applications and is described in a sepa-

rate brochure.

The GSI range is qualified for inside containment and

therefore also for outside containment. It can be adapted to

various valve requirements. Due to the possible combinations

with AUMA SAN or SAI actuators, available in a number of

sizes and versions, various solutions for the automation of

part-turn valves can be found. A multi-turn actuator and

part-turn gearbox form a part-turn actuator. Combinations

with multi-turn actuators from the SAN range are approved

for outside containment, combinations with SAI multi-turn

actuators are for inside containment.

Part-turn valves within a nuclear power plant can be auto-

mated using these combinations. The largest combinations

provide torques up to 24,000 Nm.

For information on the SAN and SAI multi-turn actuators

Shutting off, positioning, controlling

The duty type is an important selection criteria for gear-

boxes used in combination with a multi-turn actuator. Is the

valve to be used as shut-off device (open-close duty), is the

valve to be positioned in mid-travel (positioning mode) or is

the valve a control valve where the valve position is to be

changed at short interval, i.e. to control the flow through a

pipeline (modulating duty)? These are essential factors for siz-

ing the valve but also the actuator and the gearbox as the

load may vary considerably depending on the operation

mode.

AUMA part-turn gearboxes are suitable for open-close and

positioning duty, up to size GSI 160.3 also for modulating

duty.

Versions

There are clockwise and counterclockwise closing valves;

both versions can be used within a single plant. However, a

uniform closing direction within the entire power plant is

required. For this reason GSI gearboxes are available as clock-

wise closing and counterclockwise closing versions. For exam-

ple, you close a counterclockwise closing valve with a clock-

wise rotation at the gearbox input.

To be able to consider the different mounting positions in

your installation, we offer gearboxes with input shafts either

on the left side or the right side.

In total, there are four versions.

Torques up to 24,000 Nm.The combination of an SAI multi-turn actua-

tor [1] with a GSI worm gearbox or of an SANmulti-turn actuator [2] with a GSI worm gear-box form a part-turn actuator. The gearbox in-put of the worm gearbox includes a mountingflange for the actuator. The multi-turn actuatoris mounted with a screw connection to thegearbox which can easily be removed for main-tenance purposes. The flange connection be-tween multi-turn actuator meets the require-ments of EN ISO 5210 or DIN 3210 as an alter-native.Combinations of SAI and GSI are qualified forinside containment, SAN and GSI for outsidecontainment.

[3] Worm gearbox versions

The first letter in the version designation in-dicates the position of the input shaft with re-gard to the worm wheel, the second letter thedirection of rotation of the gearbox output forclockwise rotation at the gearbox input.RR, for example, means an input shaft on theright, the direction of rotation at the output isthe same as at the gearbox input.LL, on the other hand, means an input shaft onthe left, the direction of rotation at the input isreversed at the gearbox output.

[4] Worm gearbox with primary reductiongearing

The primary reduction gearing is mountedat the gearbox input to further reduce the re-quired input torques. Therefore, a rather smalland more cost-effective multi-turn actuator canbe combined with a large worm gearbox. It hasto be verified whether the increased operatingtime caused by the additional reduction isacceptable.

[4]

[5]

[6] Primary reduction gearing

The primary reduction gearing utilises plane-tary gears to reduce the required input torque.

[7] Flange for mounting the multi-turnactuator

This flange is used for the mechanical con-nection between the SAN or SAI multi-turn ac-tuator and the gearbox. The flange sizes are ac-cording to EN ISO 5210(optional DIN 3210).

[8] Pointer cover

The pointer cover follows the travel, contin-uously showing the valve position and can alsobe used as running indication.

[8]

Valve attachmentThe valve attachment is designed according

to EN ISO 5211.The gearbox can be positioned on the valve atevery 90°.

[2][7]

[6]

[7]

HousingThe housing is made of spheroidal cast iron

GJS-400-15. This material is resistant to extremevibrations caused e.g. by an earthquake or anairplane crash.

CouplingThe separate coupling enables easier mount-

ing of the gearbox to the valve. On request,the coupling is supplied with a suitable hole.The coupling with bore is placed on the valveshaft and secured against axial movement.Then, the gearbox is fitted onto the valveflange (refer also to page 14).

End stopsThe internal end stops limit the swing angle.

The significant advantage of the AUMA designis that only the comparatively low input torqueacts on the end stops, not the high outputtorque. Thereby a high level of safety againstdamage due to overload is assured (refer alsoto page 9).

Service conditions

Devices for use in nuclear power plants have to remain

fully operable, not only under normal operation, but also

under DBE conditions.

During comprehensive testing the devices have to with-

stand the most extreme loads and conditions.

Corrosion protection/ColourCorrosion protection KI

This corrosion protection was specially developed for

AUMA devices used in nuclear power plants.

All outside parts as well as the coatings are free from alu-

minium. Housing parts are sandblasted before painting. A

primer coating and two intermediate coats are applied to this

surface before finish coating.

A decontaminable two-component paint is used for finish

coating.

The total film thickness is at least 280 μm.

Colour

The standard colour of the finish coating is silver-grey

(RAL 7001). Other colours are available on request.

Ambient temperaturesThe specified values are also valid for high humidity

(> 95 %).

Normal operation■ – 25 °C to + 80 °C

DBE conditions■ up to + 185 °C for a short period

Enclosure protectionIP 68-6-D

According to EN 60 529, the conditions to fulfil enclosure

protection IP 68 are not defined. For enclosure protection

IP 68-6-D, AUMA has agreed the following with the users:

The gearboxes are dust and water tight up to a maximum

of 6 m head of water.

Functions

The basic function of the GSI part-turn gearboxes is to

decrease the input torque required at the valve by means of

a reduction ratio.

The demands on the device are high and clearly stipulated

in the corresponding standards, e.g. IEEE 382. The gearboxes

have to operate reliably over the entire planned operation

time of the power plant and even under DBE conditions.

Furthermore installation and commissioning should be easy

and the maintenance requirements low. Revision work and

inspections can be quickly and easily performed and therefore

standstill times are considerably reduced.

The high demands on availability and ease of maintenance

can only be met by a sophisticated design. The GSI gearbox

range is an excellent example of this.

Limitation of the swing angleThe actuator is equipped with a limit switching which trips

the actuator when reaching the end position. During commis-

sioning the end stops have to be set shortly after the switch-

ing points of the limit switching; contact is not made with

them during motor operation. They are used for safety rea-

sons if the limit switching fails.

When operating such a valve via the actuator handwheel,

e.g. during commissioning or in emergency mode, the valve

can only be positioned precisely in the end position if the end

stops have been set. This is particularly important if the posi-

tion indication on the valve or the gearbox is not visible.

In general the end stops limit the swing angle within the

valve. However there are valves without internal end stops,

e.g. ball valves. The end stops within the gearbox will then

assume this function.

Swing angle ranges

Most part-turn valves require a 90° movement for covering

the travel from OPEN to CLOSED. Some valves require other

swing angles. For this reason, the GSI part-turn gearboxes

have different swing angle ranges. The swing angle can be

set within the ranges indicated in the table.

Gearboxes Swing angle ranges

GSI 160.3 – GSI 250.3 Standard80° – 100°Options20° – 40°, 40° – 60°, 60° – 80°

| 11

High safety against fractureDue to the special AUMA design, the gearboxes have a

high end stop strength, which is several times the maximum

input torque. The end stops therefore provide a high degree

of protection against passing the end positions, if, for exam-

ple, an end stop breaks within the valve or the limit seating

fails.

End stops for sizes GSI 160.3 – GSI 250.3.

[1] End stop OPEN (yellow)

[2] End stop CLOSED (violet)[3] Travelling nut (blue)

The travelling nut moves back and forth on a thread between thetwo end stops. Only the comparatively low input torque acts on the endstops, not the high output torque. The forces are contained in the endstop and the worm shaft, the housing is not affected. Should an endstop break due to extreme overload, the housing is not damaged and thegearbox can be repaired.

[1]

[2][3]

Simple and precise setting of the endpositionsSetting an end position

The swing angle of the gearbox is generally set in the fac-

tory to the swing angle required on site, i.e. the swing angle

between valve position OPEN and CLOSED may not be

changed. During commissioning, only one end stop has to

be set; the other end stop will automatically be set via the

preset swing angle.

Changing the swing angle

Only if the swing angle set in the factory is not correct

and has to be adjusted, have the two end positions to be set

separately.

Functions

Protection against accidental changing of the valve positionGravity, vibrations or forces acting upon the medium

within a pipeline may lead to accidental changes in the valve

position. This has to be prevented.

Self-locking

Due to their design, the valve gearboxes counteract

torques acting upon the output side with a load. If the load

prevents the valve position from being changed from stand-

still, this is called self-locking.

The gearboxes are self-locking when at standstill under

normal service conditions. This is enhanced by the self-locking

effect of the actuator. Strong vibrations may cancel the

self-locking effect. In this case, special measures have to be

taken.

The self-locking effect of the SAI [2] or SAN [3] multi-turn actuator addsto the self-locking effect of the gearbox.

Signals/indication

The feedback signals required for the process are provided

by the multi-turn actuator mounted to the gearbox. This

includes end position and torque signals or a continuous

position feedback signal.

In addition to the DCS, the operator on site also has to

know the valve position for target-oriented operation. Highly

visible display elements are therefore required.

Local indicationIn the basic version, the gearboxes are equipped with a

pointer cover, providing the following information:

Valve end position

The end position symbols indicate that an end position has

been reached.

Valve position

Via the pointer position you may estimate the valve posi-

tion.

Valve is running

The pointer cover is coupled directly to the worm wheel

and therefore to the valve shaft. Any valve operation is reli-

ably indicated.

14 |

Valve attachment

The gearbox is mounted to the valve using a mounting

flange standardised according to EN ISO 5211.

The torque is transmitted to the valve shaft via a separate

coupling. In the basic version, the coupling is unbored; it may

also be provided with the bores shown below.

In case of special valve designs with a low valve stem or if an

intermediate flange is required between gearbox and valve,

the coupling might be too short. For such cases, the coupling

is also available in an extended version.

If the coupling is bored, it is supplied with agrub screw to fasten the coupling to the valveshaft.

[1] Bore with keyways

The bore according to EN ISO 5211 can besupplied with one or two keyways. Thekeyways conform to DIN 6885 P1. For keywayswith other dimensions please contact AUMA.

[2] Square bore

according to EN ISO 5211 or with special di-ameter.

[3] Bore with two-flats

according to EN ISO 5211 or with special di-ameter.

LifetimeWithin the framework of the qualification (see page 8) the

gearboxes were subject to extensive lifetime tests.

Open-close duty■ 5,000 operating cycles (OPEN - CLOSE - OPEN) according

to IEEE 382-1996

For the entire lifetime, 50% of the nominal torque was

operated for 80° and 120% of the nominal torque for the

residual angle of 10°. For larger swing angles, the lifetime is

reduced accordingly by the factor “set swing angle divided by

90°”.

Modulating duty■ min. 2.5 million modulating steps

During the test, control steps of approx. 1° were operated

within a range of 20° – 60° at the max. modulating torque

at the drive shaft.

Quality is not just a matter of trust

Quality is not just a matter of trustActuators must be reliable and dependable. They deter-

mine the cycle of accurately defined work processes.

But reliability does not begin during commissioning. It

begins with a well thought out design and careful selection

of materials. This continues with conscientious production

using ultra-modern machinery in clearly controlled and super-

vised steps, while keeping in mind the environment.

At AUMA, quality management is monitored on a daily

basis. Numerous customer and independent audits, backed

by ISO 9001 and ISO 14001 certification confirm these high

standards.
