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 5827 Electric Actuator orType 3374 Electric Actuator) is designed to regulate the flow rate, pressure or temperature ofliquids, gases or vapors. The valve with its actuator is designed to operate under exactly defined 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 specifications used for sizing the valve at the ordering stage. In case operators intend to use thecontrol valve in applications or conditions other than those specified, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the device for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.
Reasonably foreseeable misuse
The control valve is not suitable for the following applications:− Use outside the limits defined during sizing and by the technical data
− Use outside the limits defined 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
Qualifications of operating personnel
The control valve must be mounted, started up, serviced and repaired by fully trained andqualified personnel only; the accepted industry codes and practices must 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 totheir specialized training, their knowledge and experience as well as their knowledge of theapplicable standards.
Work on electrical installations is to be performed only by certified electricians and in compliance with all safety requirements.

Safety instructions and measures

Personal protective equipment
SAMSON recommends 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 withhot, cold and/or corrosive media− Wear hearing protection when working near the valve− Hard hat− Safety harness, e.g. when working at height− Safety footwear, if applicable ESD (electrostatic discharge) footwear
Î Check with the plant operator for details on further protective equipment.
Revisions and other modifications
Revisions, conversions or other modifications 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. Furthermore, 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 (seethe 'Design and principle of operation' chapter) 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 specified 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. Plant
operators and operating personnel must observe all hazard statements, warnings and caution notes in these mounting and operating instructions.

1-2

EB 8111/8112 EN

Safety instructions and measures

Hazards resulting from the special working conditions at the installation site of the valve mustbe identified in a risk assessment and prevented through the corresponding safety instructions drawn up by the operator.
Responsibilities of the operator
Operators are responsible for proper use 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, operators must ensure that operating personnel or third parties are not exposed toany danger.
Operators are additionally responsible for ensuring that the limits for the product defined 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 andtemperatures) 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 aswell as the referenced documents and observe the specified hazard statements, warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicablehealth, 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 Directive 2014/68/EU, Machinery Directive 2006/42/EC, Directive 2016 No. 1105 Pressure
Equipment (Safety) Regulations 2016 and Directive 2008 No. 1597 Supply of Machinery(Safety) Regulations 2008. Valves with a CE marking and/or UKCA marking have a declaration of conformity, which includes information about the applied conformity assessment
procedure. The 'Certificates' chapter contains this declaration of conformity.
According to the ignition hazard assessment performed in accordance with Clause 5.2 of
ISO 80079-36, 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 thescope of Directive 2014/34/EU.
Î For connection to the equipotential bonding system, observe the requirements specified in
Clause 6.4 of EN 60079-14 (VDE 0165-1).

Design and principle of operation

3 Design and principle of operation
The Type 3321 Valve is a single-seatedglobe valve. This valve is preferably to be
combined with the following SAMSON actuators:− Type 3371 Pneumatic Actuator− Type 3372 Electropneumatic Actuator− Type 3374 Electric Actuatorconnected to the actuator stem (A3/A7) by astem connector (A30/A31) and sealed by
the spring-loaded packing (15).
The process medium flows through the valve
in the direction indicated by the arrow in theflow-to-open direction. The plug position determines the cross-sectional area between
the seat and plug.
The position of the plug is changed by thecontrol signal acting on the actuator.

Design and principle of operation

3.1 Fail-safe action

3.2 Versions

The fail-safe position of the control valve upon air supply or control signal failure depends on the actuator used (see associatedactuator documentation). The fail-safe actionof SAMSON actuators is specified on the actuator nameplate.

With insulating section

Upon supply voltage failure, the Type 3374
Electric Actuator (version with fail-safe actiononly) 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, thevalve has one of the following fail-safe positions:
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.
Tip
The direction of action of the electric andelectropneumatic actuators is determined by
the actuator version.
The direction of action of the Type 3371
Pneumatic Actuator can be reversed, if required. See the mounting and operating instructions u EB 8317.

EB 8111/8112 EN

The modular design allows an insulating section to be fitted to the standard valve version.
Actuators
In these instructions, the preferable combination with one of the following SAMSON actuators is described.
− Type 5827 Electric Actuator− Type 3374 Electric Actuator− Type 3372 Electropneumatic Actuator− Type 3371 Pneumatic Actuator

3.3

Additional fittings

Strainers
We recommend installing a SAMSON
strainer upstream of the valve. It prevents solid particles in the process medium fromdamaging the valve.
Bypass and shut-off valves
We recommend installing a shut-off valve
both upstream of the strainer and downstream of the valve and installing a bypass
line. The bypass ensures that the plant does
not need to be shut down for service and repair work on the valve.
Insulation
Control valves can be insulated to reduceheat energy transfer. Refer to the instructionsin the 'Installation' chapter.

3-3

Design and principle of operation

Safety guard

Temperature range

For operating conditions that require increased safety (e.g. in cases where the valve
is freely accessible to untrained staff), a safety guard must be installed to rule out a crush
hazard arising from moving parts (actuatorand plug stem). Plant operators are responsible for deciding whether a guard is to be
used. The decision is based on the risk posedby the plant and its operating conditions.

Depending on the version, the control valve
is designed for a temperature range from–10 to +220 °C (14 to 430 °F).

Noise reduction
Trims with flow dividers can be used to reduce noise emission (u T 8081).

3.4 Valve accessories
Information Sheet u T 8350

3.5 Technical data
The nameplates on the valve and actuator
provide information on the control valve version. See the 'Markings on the device' chapter.
Note
More information is available in Data Sheetsu T 8111 and u T 8112.

The use of an insulating section can extend
the temperature range to +300 °C (+572 °F)
depending on the properties of the materials
used.

Installation

Plant operators must ensure that, after installation of the device, the operating personnel
can perform all necessary work safely andeasily access the device from the work position.
Pipeline routing
The inlet and outlet lengths (see Table 5-1)
vary depending on several variables andprocess conditions and are intended as recommendations. Contact SAMSON if thelengths are significantly shorter than the recommended lengths.
To ensure that the valve functions properly,
proceed as follows:Î Observe the recommended inlet andoutlet lengths (see Table 5-1). Contact
SAMSON if the valve conditions or statesof the medium process deviate.
Î Install the valve free of stress and with theleast amount of vibrations as possible.
Read information under “Mounting position” and “Fail-safe position with pneumatic actuators with integrated springs”
in this chapter.
Î Install the valve allowing sufficient space
to remove the actuator and valve or toperform service and repair work on
them.
Mounting position
Generally, SAMSON recommends installingthe valve with the actuator upright and on
top of the valve.

Support or suspension
Note
The plant engineering company is responsible for selecting and implementing a suitablesupport or suspension of the installed control
valve and the pipeline.
Depending on the valve version and mounting position, the valve, actuator and pipeline
must be supported or suspended.
Valves, which are not installed in the pipeline in the upright position with the actuatoron top, must be supported or suspended.
Valve accessoriesÎ During connection of valve accessories,
make sure that they are easily accessible
and can be operated safely from thework position.
Vent plugs
Vent plugs are screwed into the exhaust air
ports of pneumatic and electropneumatic devices. They ensure that any exhaust air that
forms can be vented to the atmosphere (toavoid excess pressure in the device). Furthermore, the vent plugs allow air intake to prevent a vacuum from forming in the device.
Î Locate the vent plug on the opposite side
to the work position of operating personnel.

Î Contact SAMSON if the mounting position is not as specified above.

u EB 5827-X for Type 5827 Actuator
u EB 8331-X for Type 3374 Actuator− u AB 0100 for tools, tightening torques
and lubricant! DANGER
Risk of bursting due to incorrect opening ofpressurized equipment or components.
Valves and pipelines are pressure equipmentthat may burst when handled incorrectly.
Flying projectile fragments or the release ofprocess medium under pressure can cause
serious injury or even death.
Before working on the control valve:Î Depressurize all plant sections affected
and the valve (including the actuator).
Release any stored energy.
Î Drain the process medium from the plant
sections affected as well as from thevalve.

EB 8111/8112 EN! WARNING
Risk of burn injuries due to hot or cold components and pipeline.
Valve components and the pipeline may become very hot or cold. Risk of burn injuries.
Î Allow components and pipelines to cool
down or warm up to the ambient temperature.
Î Wear protective clothing and safety
gloves.
! WARNING
Risk of hearing loss or deafness due to loudnoise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by theprocess medium and the operating
conditions. Additionally, a loud noise may
briefly occur through the sudden venting of
the pneumatic actuator or pneumatic valve
accessories not fitted with noise-reducing
fittings. Both can damage hearing.
Î Wear hearing protection when working
near the valve.
! WARNING
Crush hazard arising from actuator andplug stem moving.
Î Do not insert hands or finger into theyoke while the air supply or voltage supply is connected to the actuator.
Î Before working on the control valve,

supply and the control signal or

9-1Servicing

disconnect the supply voltage and protect
it against unintentional reconnection.
Î Do not impede the movement of the actuator and plug stem by inserting objects
into the yoke.
Î Before unblocking the actuator and plug
stem after they have become blocked(e.g. due to seizing up after remaining inthe same position for a long time), release any stored energy in the actuator(e.g. spring compression). See associated actuator documentation.
! WARNING
Risk of personal injury due to exhaust air
being vented from pneumatically operated
components.
While the valve is operating, air is vented
from the actuator, e.g. during closed-loop
operation or when the valve opens or closes.
Î Wear eye protection when working inclose proximity to the control valve.
! WARNING
Risk of personal injury due to preloaded
springs in pneumatic actuators.
Actuators with preloaded springs are under
tension. They can be identified by the longbolts protruding from the bottom of the actuator.
Î Before starting any work on the actuator,
relieve the compression from the preloaded springs (see associated actuator
documentation).

9-2! WARNING
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual medium can flow out of the valve and, depending on its properties, cause personal injury,
e.g. (chemical) burns.
Î Wear protective clothing, safety gloves,
respiratory protection and eye protection.
! NOTICE
Risk of control valve damage due to overor under-torquing.
Observe the specified torques when tightening control valve components. Excessive
tightening torques lead to parts wearing out
more quickly. Parts that are too loose may
cause leakage.
Î Observe the specified tightening torques(u AB 0100.).
! NOTICE
Risk of valve damage due to the use of unsuitable tools.
Î Only use tools approved by SAMSON(u AB 0100).

SAMSON recommends the following inspections and tests:
Inspection and testing

Recommended action to be taken in the event of a negative
resultCheck the markings, labels andnameplates on the valve for theirreadability and completeness.

Immediately renew damaged, missing or incorrect
nameplates or labels.

Check the valve for external damage
that could impair the proper
functioning of the control valve oreven its safe operation.

Repair any damage immediately. If necessary, put the control
valve out of operation (see the 'Decommissioning' chapter).

Check the valve accessories to ensure
they are mounted properly.

Tighten the connections of the valve accessories.

Seat leakage (without testing to checkthat the leakage class requirements
are met)Shut off the section of the pipeline and flush the valve to
remove any dirt and/or deposited foreign particles between
the seat and plug.

External leakage (fugitive emissions):
Inspect the control valve at thepossible points of leakage to ensure
there is no leakage.

Check flanged joints (tightening torques).

Clean any inscriptions that are covered with dirt and are
illegible.

Replace the gaskets at the flanged joints. For this purpose, put
the control valve out of operation (see the 'Decommissioning'
chapter).
Replace the packing. For this purpose, put the control valve
out of operation (see the 'Decommissioning' chapter).

Check to ensure that the actuator andplug stem move smoothly.

If the actuator and plug stem is blocked, put the control valve
out of operation (see the 'Decommissioning' chapter) andremove the blockage.
WARNING! A blocked actuator or plug stem (e.g. due toseizing up after remaining in the same position for a longtime) can suddenly start to move uncontrollably. Injury tohands or fingers is possible if they are inserted into theactuator or valve.
Before trying to unblock the actuator or plug stem, disconnect
and lock the pneumatic air supply as well as the control
signal or disconnect the supply voltage and protect it against
unintentional reconnection. Before unblocking the actuator,
release any stored energy in the actuator (e.g. spring
compression). See associated actuator documentation.

If possible, check the valve's fail-safe
position by briefly interrupting the air
supply.
