1 Safety instructions and measures
Intended use
TheType3354GlobeValveisdesignedforon/offserviceinprocessengineeringandplants
with industrial requirements. The valve is suitable for liquids, vapors and gases at tempera-
turesfrom–10to+180°CandanominalpressureofPN16.Theglobevalveiscombined
with a pneumatic piston actuator.
Thecontrolvalveisdesignedtooperateunderexactlydenedconditions(e.g.operating
pressure, process medium, temperature). Therefore, operators must ensure that the control
valveisonlyusedinoperatingconditionsthatmeetthespecicationsusedforsizingthe
valve at the ordering stage. In case operators intend to use the control valve in applications
orconditionsotherthanthosespecied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefertothetechnicaldataandnameplateforlimitsandeldsofapplicationaswellas
possible uses.
Reasonably foreseeable misuse
The control valve is not suitable for the following applications:
− Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
− Useoutsidethelimitsdenedbythevalveaccessoriesconnectedtothevalve
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
Qualications of operating personnel
The control valve must be mounted, started up, serviced and repaired by fully trained and
qualiedpersonnelonly;theacceptedindustrycodesandpracticesmustbeobserved.Ac-
cording to these mounting and operating instructions, trained personnel refers to individuals
whoareabletojudgetheworktheyareassignedtoandrecognizepossiblehazardsdueto
theirspecializedtraining,theirknowledgeandexperienceaswellastheirknowledgeofthe
applicable standards.

Safety instructions and measures
Personal protective equipment
Werecommendcheckingthehazardsposedbytheprocessmediumbeingused(e.g.
uGESTIS(CLP)hazardoussubstancesdatabase).Dependingontheprocessmediumand/
or the activity, the protective equipment required includes:
− Protective clothing, gloves, eye protection and respiratory protection in applications with
hot,coldand/orcorrosivemedia
− Wear hearing protection when working near the valve
− Hard hat
− Safety harness when working at height
− Safety footwear, ESD (electrostatic discharge) footwear, if necessary
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAMSON.
Theyareperformedattheuser'sownriskandmayleadtosafetyhazards,forexample.Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety features
Upon supply air or control signal failure, the valve moves to a certain fail-safe position (see
'Design and principle of operation' section).
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
preventhazardsthatcouldbecausedinthecontrolvalvebytheprocessmedium,theoperat-
ing pressure, the signal pressure or by moving parts by taking appropriate precautions. Plant
operatorsandoperatingpersonnelmustobserveallhazardstatements,warningandcaution
notes in these mounting and operating instructions.
Hazardsresultingfromthespecialworkingconditionsattheinstallationsiteofthevalvemust
beidentiedinariskassessmentandpreventedthroughthecorrespondingsafetyinstruc-
tions drawn up by the operator.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.

EB 8140 EN 1-3
Safety instructions and measures
Operatorsareadditionallyresponsibleforensuringthatthelimitsfortheproductdenedin
the technical data are observed. This also applies to the start-up and shutdown procedures.
Start-up and shutdown procedures fall within the scope of the operator's duties and, as such,
are not part of these mounting and operating instructions. SAMSON is unable to make any
statements about these procedures since the operative details (e.g. differential pressures and
temperatures) vary in each individual case and are only known to the operator.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthereferenceddocumentsandobservethespeciedhazardstatements,warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards, directives and regulations
The control valves comply with the requirements of the European Pressure Equipment Direc-
tive 2014/68/EU and the Machinery Directive 2006/42/EC. Valves with a CE marking
have a declaration of conformity which includes information about the applied conformity
assessmentprocedure.The'Certicates'sectioncontainsthisdeclarationofconformity.
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
− Mounting and operating instructions for mounted valve accessories (positioner, solenoid
valve etc.), for example uEB8357forType4740LimitSwitch

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equipment. Impermissible pressure or improper open-
ing can lead to valve components bursting.
ÎObserve the maximum permissible pressure for valve and plant.
ÎBeforestartinganyworkonthecontrolvalve,depressurizeallplantsectionsaffect-
ed as well as the valve.
ÎDrain the process medium from all the plant sections concerned as well as the valve.
1.2 Notes on possible personal injury
WARNING
!
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, valve components and pipelines may get very hot
or cold and cause burn injuries.
ÎAllow components and pipelines to cool down or warm up to the ambient tempera-
ture.
ÎWear protective clothing and safety gloves.
Risk of hearing loss or deafness due to loud noise.
The noise emissions depend on the valve version, plant facilities and process medium.
ÎWear hearing protection when working near the valve.
Risk of personal injury due to exhaust air being vented.
While the valve is operating, air is vented from the actuator, for example, during
closed-loop operation or when the valve opens or closes.
ÎInstall the control valve in such a way that vent openings are not located at eye level
and the actuator does not vent at eye level in the work position.
ÎUse suitable silencers and vent plugs.
ÎWear eye protection when working in close proximity to the control valve.

EB 8140 EN 1-5
Safety instructions and measures
WARNING
!
Risk of personal injury due to preloaded springs.
Controlvalvesttedwithpreloadedspringsareundertension.
ÎOnlyopenthevalvebody/actuatorfollowingtheinstructionsinthisdocument(see
the 'Servicing' section > 'Replacing the gaskets' or 'Replacing the packing').
Risk of personal injury due to residual process medium in the valve.
Whileworkingonthevalve,residualmediumcanowoutofthevalveand,depending
on its properties, cause personal injury, e.g. (chemical) burns.
ÎIf possible, drain the process medium from all the plant sections affected and the
valve.
ÎWear protective clothing, safety gloves, respiratory protection and eye protection.
Exposure to hazardous substances poses a serious risk to health.
Certainlubricantsandcleaningagentsareclassiedashazardoussubstances.These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.
ÎMakesurethatanMSDSisavailableforanyhazardoussubstanceused.Ifneces-
sary, contact the manufacturer to obtain an MSDS.
ÎInformyourselfaboutthehazardoussubstancesandtheircorrecthandling.
Risk of personal injury through incorrect operation, use or installation as a result of
information on the valve being illegible.
Over time, markings, labels and nameplates on the valve may become covered with dirt
orbecomeillegibleinsomeotherway.Asaresult,hazardsmaygounnoticedandthe
necessary instructions not followed. There is a risk of personal injury.
ÎKeep all relevant markings and inscriptions on the device in a constantly legible
state.
ÎImmediately renew damaged, missing or incorrect nameplates or labels.

1.3 Notes on possible property damage
NOTICE
!
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
ÎFlush the pipelines before start-up.
Risk of valve damage due to unsuitable medium properties.
Thevalveisdesignedforaprocessmediumwithdenedproperties.
ÎOnlyusetheprocessmediumspeciedforsizingtheequipment.
Risk of leakage and valve damage due to excessively high or low tightening torques.
Observethespeciedtorqueswhentighteningcontrolvalvecomponents.Excessive
tightening torques lead to parts wearing out more quickly. Parts that are too loose may
cause leakage.
ÎObservethespeciedtighteningtorques(seethe'Tighteningtorques'sectioninAn-
nex).
Risk of valve damage due to the use of unsuitable tools.
Certain tools are required to work on the valve.
ÎOnly use tools approved by SAMSON.
Risk of valve damage due to the use of unsuitable lubricants.
The lubricants to be used depend on the valve material. Unsuitable lubricants may cor-
rode and damage surfaces.
ÎOnly use lubricants approved by SAMSON.

Design and principle of operation
3 Design and principle of oper-
ation
The pneumatic control valve consists of a
globe (T-pattern) valve with a soft-seated
plug and a pneumatic piston actuator.
Themediumowsthroughthevalveinthe
direction indicated by the arrow. The signal
pressure applied to the piston actuator deter-
mines the position of the plug and thus the
cross-sectionalareaofowbetweentheseat
and plug.
Theplug/actuatorstem(2)issealedbya
self-adjusting PTFE V-ring packing (4.4) at
the valve and by a radial shaft seal (4.1) at
the actuator.

Design and principle of operation
3.1 Fail-safe action
The fail-safe position of the valve upon sup-
ply air (signal pressure) failure is determined
by how the piston and actuator spring are
arranged in the pneumatic actuator.
Fail-close(FA/NC)
The actuator spring closes the valve upon air
supply failure. The valve opens when the sig-
nal pressure increases.
Fail-open (FE/NO)
The actuator spring opens the valve upon air
supply failure. The valve closes when the sig-
nal pressure increases.

id particles in the process medium from
damaging the valve.
Bypass and shut-off valves
We recommend installing a shut-off valve
both upstream of the strainer and down-
stream of the valve and installing a bypass
line. The bypass ensures that the plant does
not need to be shut down for service and re-
pair work on the valve.
3.5 Technical data
The nameplates on the valve and actuator
provide information on the control valve ver-
sion. See the 'Markings on the device' sec-
tion.
More information is available in Data Sheet
uT8140.
Noise emissions
SAMSON is unable to make general state-
ments about noise emissions. The noise emis-
sions depend on the valve version, plant fa-
cilities and process medium.
