1 Safety instructions and measures
Intended use
TheSAMSONType3321GlobeValveincombinationwithanactuator(e.g.Type3371
PneumaticActuator,Type3372ElectropneumaticActuator,Type5824ElectricActuatoror
Type3374ElectricActuator)isdesignedtoregulatetheowrate,pressureortemperatureof
liquids, gases or vapors. The valve with its actuator 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otherapplicationsorconditionsthan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 in these instructions
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aretobeobserved.
According 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.
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:

1-2 EB 8111/8112 EN
Safety instructions and measures
−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
The fail-safe position of the control valve upon air supply or control signal failure depends on
the actuator used (see associated actuator documentation). When the valve is combined with
one of the following SAMSON actuators, the valve moves to a certain fail-safe position (see
the 'Design and principle of operation' section) upon supply air or control signal failure.
−Type3371PneumaticActuator
−Type3372ElectropneumaticActuator
−Type3374ElectricActuator(versionwithfail-safeactiononly)
Thefail-safeactionoftheactuatoristhesameasitsdirectionofactionandisspeciedon
the nameplate of SAMSON actuators.
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
operating pressure, the signal pressure or by moving parts by taking appropriate
precautions.They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.

EB 8111/8112 EN 1-3
Safety instructions and measures
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, the operator must ensure that operating personnel or third persons are not ex-
posed to any danger.
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, the operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards and regulations
The control valves comply with the requirements of the European Pressure Equipment
Directive2014/68/EU.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.
AccordingtotheignitionriskassessmentperformedinaccordancewithEN13463-1:2009,
section 5.2, the non-electrical control valves do not have their own potential ignition source
even in the rare incident of an operating fault. As a result, they do not fall within the scope of
Directive 2014/34/EU.
ÎForconnectiontotheequipotentialbondingsystem,observetherequirementsspeciedin
section6.4ofEN60079-14(VDE0165-1).

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
opening 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.
Risk of electric shock.
ÎDo not remove any covers to perform adjustment work on live parts.
ÎBeforeperforminganyworkonthedeviceandbeforeopeningthedevice,discon-
nect the supply voltage and protect it against unintentional reconnection.
ÎOnly use power interruption devices that are protected against unintentional recon-
nection of the power supply.
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 heat up.
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.

EB 8111/8112 EN 1-5
Safety instructions and measures
WARNING
!
Risk of personal injury due to exhaust air being vented from pneumatically operated
components.
While the valve is operating, the pneumatic actuator may vent during closed-loop con-
trol or when the valve opens or closes.
ÎInstall the control valve in such a way that vent holes 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.
Risk of personal injury due to preloaded springs.
Valves in combination with pneumatic actuators with preloaded springs are under ten-
sion.ThesecontrolvalveswithSAMSONpneumaticactuatorscanbeidentiedbythe
long bolts protruding from the bottom of the actuator.
ÎBeforestartinganyworkontheactuator,relievethecompressionfromthepreload-
ed springs (see associated actuator documentation).
Crush hazard arising from moving parts.
The control valve contains moving parts (actuator and plug stem), which can injure
handsorngersifinsertedintothevalve.
ÎDonotinserthandsorngerintotheyokewhilethevalveisinoperation.
ÎBeforeworkingonthecontrolvalve,disconnectandlockthepneumaticairsupply
as well as the control signal.
ÎDisconnect the supply voltage before performing any work on the control valve.
ÎDo not impede the movement of the actuator and plug stem by inserting objects into
the yoke.
ÎBeforeunblockingtheactuatorandplugstemaftertheyhavebecomeblocked(e.g.
duetoseizingupafterremaininginthesamepositionforalongtime),releaseany
stored energy in the actuator (e.g. spring compression). See associated actuator
documentation.

1-6 EB 8111/8112 EN
Safety instructions and measures
WARNING
!
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual process medium can escape and, depending on
its properties, may lead to 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.
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 damage to the electric control valve due to the power supply exceeding the
permissible tolerances.
The electric control valves are designed for use according to regulations for low-voltage
installations.
ÎObserve the permissible tolerances of the power supply. See associated actuator
documentation.
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.

EB 8111/8112 EN 1-7
Safety instructions and measures
NOTICE
!
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.
Risk of leakage and valve damage due to excessively high or low tightening torques.
Observethespeciedtorquesontighteningcontrolvalvecomponents.Excessivelytight-
ened torques lead to parts wearing out quicker. Parts that are too loose may cause leak-
age.
ÎObservethespeciedtighteningtorques(uAB0100).
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 (uAB0100).
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 the surface.
ÎOnly use lubricants approved by SAMSON (uAB0100).
Risk of contamination of the process medium through the use of unsuitable lubricants
and/or contaminated tools and components.
ÎIf necessary, keep the valve and the tools used free from solvents and grease.
ÎMake sure that only suitable lubricants are used.

Design and principle of operation
3 Design and principle of oper-
ation
TheType3321Valveisasingle-seated
globe valve. This valve is preferably to be
combined with the following SAMSON actu-
ators:
−Type 3371 Pneumatic Actuator
−Type3372ElectropneumaticActuator
−Type3374ElectricActuator
−Type5824ElectricActuator
The seat (4) and plug with plug stem (5) are
installed in the body (1). The plug stem is
connectedtotheactuatorstem(A3/A7)bya
stemconnector(A30/A31)andsealedby
the spring-loaded packing (15).
Theprocessmediumowsthroughthevalve
in the direction indicated by the arrow in the
ow-to-opendirection.Theplugpositionde-
termines the cross-sectional area between
the seat and plug.
The position of the plug is changed by the
control signal acting on the actuator.

Design and principle of operation
3.1 Fail-safe action
The fail-safe position of the control valve up-
on air supply or control signal failure de-
pends on the actuator used (see associated
actuator documentation). The fail-safe action
ofSAMSONactuatorsisspeciedontheac-
tuator nameplate.
Uponsupplyvoltagefailure,theType3374
Electric Actuator (version with fail-safe action
only) causes the valve to move to a certain
fail-safe position.
Depending on how the compression springs
arearrangedintheSAMSONType3271
andType3277PneumaticActuator,the
valve has one of the following fail-safe posi-
tions:
Actuator stem extends (FA)
Upon supply voltage or air supply failure,
the actuator stem extends causing the valve
to close.
Actuator stem retracts (FE)
Upon supply voltage or air supply failure,
the actuator stem extends causing the valve
to open.
The direction of action of the electric and
electropneumatic actuators is determined by
the actuator version.
The direction of action of the Type3371
Pneumatic Actuator can be reversed, if re-
quired. See the mounting and operating in-
structions uEB8317.
3.2 Versions
With insulating section
The modular design allows an insulating sec-
tiontobettedtothestandardvalveversion.
Actuators
In these instructions, the preferable combina-
tion with one of the following SAMSON ac-
tuators is described.
−Type5824ElectricActuator
−Type3374ElectricActuator
−Type3372ElectropneumaticActuator
−Type3371PneumaticActuator
3.3 Additionalttings
Strainers
We recommend installing a SAMSON
strainer upstream of the valve. It prevents sol-
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.
Insulation
Controlvalvescanbeinsulatedtoreduce
heat energy transfer. Refer to the instructions
in the 'Installation' section.
Tip

3-4 EB 8111/8112 EN
Design and principle of operation
Safety guard
For operating conditions that require in-
creased safety (e.g. in cases where the valve
is freely accessible to untrained staff), a safe-
ty guard must be installed to rule out a crush
hazardarisingfrommovingparts(actuator
and plug stem). Plant operators are responsi-
ble for deciding whether a guard is to be
used. The decision is based on the risk posed
by the plant and its operating conditions.
Noise reduction
Trimswithowdividerscanbeusedtore-
duce noise emission (uT8081).

is designed for a temperature range from
–10to+220°C(14to430°F).
The use of an insulating section can extend
thetemperaturerangeto+300°C(+572°F)
depending on the properties of the materials
used.
Leakage class
Depending on the version, the following
leakage class applies:
Seal (12 on nameplate) ME,
ST
ME,
ST PT, PK
Leakage class (according
toIEC60534-4or
ANSI/FCI70-2)

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.
Dimensions and weights
The dimensions and weights for the DIN ver-
sions are listed in Table 3-1.
The dimensions and weights for the ANSI
versions are listed in Table 3-2.
