1 Safety instructions and measures
Intended use
The SAMSON Type3241 Globe Valve in combination with an actuator (e.g. Type3271 or Type3277 Pneumatic 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 applications 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, SAMSON must be contacted.
SAMSON does not assume any liability for damage resulting from the failure to use the valve 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 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 in the technical data
− Use outside the limits dened by the valve accessories mounted on the control 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.

Safety instructions and measures
Personal protective equipment
We recommend wearing the following protective equipment depending on the process medi­um:
− Protective clothing, gloves and eyewear in applications with hot, cold, and/or corrosive media
− Wear hearing protection when working near the valve.
Î Check with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications to 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 devices
Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec­tion3.1). 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 (see actuator documentation).
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, especially for installation, start-up, and maintenance.
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 to the operating personnel and to instruct them in proper operation. Furthermore, operators must ensure that operating personnel or third persons are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as well as the specied hazard statements, warning, and caution notes. Furthermore, the oper­ating personnel must be familiar with the applicable health, safety and accident prevention regulations and comply with them.
Page 7
EB 8012 EN 7
Safety instructions and measures
Referenced standards and regulations
The control valves comply with the requirements of the European Pressure Equipment Direc­tive 97/23/EC. Valves with a CE marking have a declaration of conformity which includes information about the applied conformity assessment procedure. This declaration of confor­mity is included in the Appendix of these instructions (see section10.2).
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 94/9/EC.
Î For connection to the equipotential bonding system, observe the requirements specied in
section 6.3 of EN60079-14:2014-10 (VDE0165 Part 1).

Safety instructions and measures
1.2 Notes on possible personal injury
WARNING!
Crush hazard arising from moving parts.
The control valve contains moving parts (actuator and plug stems), which can in­jure hands or ngers if inserted into the valve.
Î Do not insert hands or nger into the yoke while the valve is in operation. Î While working on the control valve, disconnect and lock the pneumatic air
supply as well as the control signal.
Risk of personal injury when the actuator vents.
While the valve is operating, the actuator may vent during closed-loop control or when the valve opens or closes.
Î Install the control valve in such a way that the actuator does not vent at eye
level.
Î Use suitable silencers and vent plugs. Î Wear 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 tension. These control valves with SAMSON pneumatic actuators can be identied by the long bolts 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).
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.
Î If possible, drain the process medium from all the plant sections concerned
and the valve.
Î Wear protective clothing, gloves, and eyewear.

EB 8012 EN 9
Safety instructions and measures
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.
Î Allow components and pipelines to cool down or heat up. Î Wear protective clothing and gloves.
1.3 Notes on possible property damage
NOTICE
Risk of valve damage due to contamination (e.g. solid particles) in the pipe­line.
The plant engineering company is responsible for cleaning the pipelines in the plant.
Î Flush the pipelines before start-up. Î Observe the maximum permissible pressure for valve and plant.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for a process medium with dened properties.
Î Only use the process medium specied for sizing the valve.
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 tightened torques lead to parts wearing out quicker. Parts that are too loose may cause leakage.
Î Observe the specied tightening torques (uAB0100).

Design and principle of operation
3 Design and principle of oper-
ation
The single-seated Type3241 Globe Valve is preferably combined with a SAMSON Type3271 or Type3277 Pneumatic Actuator (see Fig.4). It can also be combined with other actuators.
The seat (4) and plug with plug stem (5) are assembled in the body (1). The plug stem is connected to the actuator stem (A7) by the stem connector clamps (A26) and is sealed by a spring-loaded V-ring packing (16). The springs in the pneumatic actuator (A) are lo­cated either above or below the diaphragm depending on the selected fail-safe action (see section3.1). A change in the signal pressure acting on the diaphragm causes the plug to move. The actuator size is deter­mined by the diaphragm area.
The medium ows through the valve in the direction indicated by the arrow. A rise in signal pressure causes the force acting on the diaphragm in the actuator to increase. The springs are compressed. Depending on the selected direction of action, the actuator stem retracts or extends. As a result, the plug position in the seat changes and determines the ow rate through the valve.

Design and principle of operation
3.1 Fail-safe positions
The fail-safe position depends on the actua­tor used.
Depending on how the compression springs are arranged in the pneumatic actuator, the valve has two different fail-safe positions:
Actuator stem extends (FA)
When the signal pressure is reduced or the air supply fails, the springs move the actua­tor stem downward and close the valve. The valve opens when the signal pressure is in­creased enough to overcome the force exert­ed by the springs.
Actuator stem retracts (FE)
When the signal pressure is reduced or the air supply fails, the springs move the actua­tor stem upwards and open the valve. The valve closes when the signal pressure is in­creased enough to overcome the force exert­ed by the springs.
Tip:
The actuator's direction of action can
be reversed, if required. Refer to the
mounting and operating instructions of the pneumatic actuator:
uEB8310‑X for Type3271 and
Type3277
3.2 Versions
The modular design allows an insulating sec­tion or metal bellows to be tted to the stan­dard valve version.
Micro-ow valve version
In the micro-ow valve version, a micro-trim element is installed in the valve body instead of the usual seat/plug assembly (Fig.6).

Design and principle of operation
Actuators
In these instructions, the preferable combina­tion with a Type3271 or Type3277 Pneu­matic Actuator is described. The pneumatic actuator (with or without handwheel) can be replaced by another pneumatic actuator in a different size, but with the same travel.
Î Observe the maximum permissible actu-
ator force.
Note:
If the travel range of the actuator is larger than the travel range of the
valve, the spring assembly in the ac­tuator must be preloaded so that the travel ranges match. See associated actuator documentation.
The basic pneumatic actuator can be re­placed by a pneumatic actuator with addi­tional handwheel or by an electric actuator.
3.3 Technical data
The nameplates on the valve and actuator provide information on the control valve ver­sion. See section2.1 and the actuator docu­mentation.
Note:
More information is available in Da­ta Sheet uT8012.
Compliance
The Type3241 Valve bears both the CE and EAC marks of conformity.
Temperature range
Depending on the version, the control valve is designed for a temperature range from –10 to +220°C (14 to 428°F). The use of an insulating section or bellows seal extends the temperature range from –196 to +450°C (–325 to +842°F).
Leakage class
Depending on the version, the following leakage class applies:
Seal (16 on name­plate)
ME, ST ME, ST PT, PK
Pressure balancing (18 on nameplate)
– D/B –
Leakage class (ac­cording to ANSI/ FCI70-2)
Min. IV Min. IV VI
Noise emission
SAMSON is unable to make general state­ments about noise emission as it depends on the valve version, plant facilities, and pro­cess medium. On request, SAMSON can perform calculations according to IEC60534, Part8-3 and Part8-4 or VD­MA24422 (edition 89).
WARNING!
Risk of hearing loss or deafness due
to loud noise.
Wear hearing protection when work-
ing near the valve.

NOTICE
Risk of valve damage due to incor-
rectly attached slings.
The welded-on lifting eyelet on SAMSON actuators is only intended for mounting and removing the actu­ator as well as lifting the actuator
without valve. Do not use this lifting
eyelet to lift the entire control valve
assembly.
− When lifting the control valve, make sure that the slings attached
to the valve body bear the entire load.
− Do not attach load‑bearing slings to the actuator, handwheel or any
other parts.
− Observe lifting instructions (see section4.2.2).
Tip:
SAMSON's After‑sales Service de­partment can provide more detailed transport and lifting instructions on
request.
4.2.1 Transporting
The control valve can be transported using lifting equipment (e.g. crane or forklift).

4.3 Storage
NOTICE
Risk of valve damage due to im-
proper storage.
− Observe storage instructions.
− Avoid long storage times.
− Contact SAMSON in case of differ- ent storage conditions or longer
storage times.
Note:
We recommend regularly checking the control valve and the prevailing storage conditions during long stor-
age times.
Storage instructions
− Protect the control valve against external inuences (e.g. impact).
− Do not damage the corrosion protection (paint, surface coatings). Remove any damage immediately.
− Protect the control valve against moisture and dirt. Store it at a relative humidity of less than 75%. In damp spaces, prevent condensation. If necessary, use a drying agent or heating.
− Make sure that the ambient air is free of acids or other corrosive media.
− The permissible storage temperature of standard control valves is –20 to +65°C (–4 to +149°F).
Note:
Contact SAMSON's After‑sales Ser­vice department for the storage tem-
peratures of other valve versions.
− Do not place any objects on the control valve.
Special storage instructions for elastomers
Elastomer, e.g. actuator diaphragm
− To keep elastomers in shape and to pre- vent cracking, do not bend them or hang them up.
− We recommend a storage temperature of 15°C (59°F) for elastomers.
− Store elastomers away from lubricants, chemicals, solutions, and fuels.
Tip:
SAMSON's After‑sales Service de­partment can provide more detailed
storage instructions on request.

Preparation
4.4 Preparation for installation
Proceed as follows:
Î Flush the pipelines.
Note:
The plant engineering company is re-
sponsible for cleaning the pipelines in the plant.
Î Check the valve to make sure it is clean. Î Check the valve for damage. Î Check to make sure that the type desig-
nation, valve size, material, pressure rat­ing and temperature range of the valve match the plant conditions (size and pressure rating of the pipeline, medium temperature etc.).
Î For steam applications, make sure that
the pipelines are dry. Moisture will dam­age the inside of the valve.
Î Check any mounted pressure gauges to
make sure they function.
Î When the valve and actuator are al-
ready assembled, check the tightening torques of the bolted joints (uAB0100). Components may loosen during trans­port.
Page 30
30 EB 8012 EN
Mounting and start-up
5 Mounting and start-up
SAMSON valves are delivered ready for use. In special cases, the valve and actuator are delivered separately and must be assem­bled on site. The procedure to mount and start up the valve are described in the follow­ing.
NOTICE
Risk of valve damage due to exces-
sively high or low tightening torques. Observe the specied torques on tightening control valve components. Excessively tightened torques lead to parts wearing out quicker. Parts that are too loose may cause leakage. Observe the specied tightening torques (uAB0100).
NOTICE
Risk of valve damage due to the use
of unsuitable tools. Only use tools approved by SAMSON (uAB0100).
5.1 Mounting the actuator onto the valve
Proceed as described in the actuator docu­mentation if the valve and actuator have not been assembled by SAMSON:
Versions with V-port plug
Each V-port plug has three V-shaped ports. Depending on the valve size, the size of the symmetrically arranged V-shaped ports var­ies. The process medium in the valve ows through the V-shaped ports as soon as the plug is lifted out of the seat (i.e. the valve opens).
1. Before mounting the actuator, determine
which V-shaped port is uncovered rst when the plug is lifted out of the seat.
Tip:
Usually, this is the largest V-shaped
port.
2. On mounting the actuator, make sure
that the V-shaped port uncovered rst faces toward the valve outlet.
NOTICE
Risk of damage to wall of valve body due to incorrectly diverted jet stream. The process medium cannot ow unobstructed through the valve when the V‑port plug has been installed incorrectly. This will result in the process medium hitting the body
wall, which may lead to severe valve
damage.
Make sure the V-port plug is installed
correctly.
Page 31
EB 8012 EN 31
Mounting and start-up
Note:
− Remove the mounted actuator be- fore mounting the other actuator
(see associated actuator documen­tation).
− Preloading the actuator springs in- creases the thrust of a pneumatic actuator and reduces the travel
range of the actuator (see associat­ed actuator documentation).
5.2 Installing the valve into the pipeline
5.2.1 Checking the installation
conditions
Pipeline routing
The inlet and outlet lengths vary depending on the process medium. To ensure the control valve functions properly, follow the installa­tion instructions given below:
Î Observe the inlet and outlet lengths (see
Table6). Contact SAMSON if the valve conditions or states of the medium pro­cess deviate.
Î Install the valve free of stress and with the
least amount of vibrations as possible. If necessary, attach supports to the valve.
Î Install the valve allowing sufcient space
to remove the actuator and valve or to perform service and repair work on them.
Mounting position
Generally, we recommend installing the valve with the actuator upright and on top of the valve.
In the following versions, the valve must be installed with the actuator on top:
− Valves in NPS4 and larger
− Valves with insulating section for low
temperatures below –10°C (14°F)
Î Contact SAMSON if the mounting posi-
tion is not as specied here.
Support or suspension
Depending on the valve version and mount­ing position, the control valve and pipeline must be supported or suspended. The plant engineering company is responsible in this case.
NOTICE
Premature wear and leakage due to
insufcient support or suspension.
In the following versions, the control valve must be supported or sus­pended:
− Valves that are not installed with the actuator upright on top of the
valve.
Attach a suitable support or suspen­sion to the valve.
Page 32
32 EB 8012 EN
Mounting and start-up
Vent plug
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 (to avoid 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 workplace of operating personnel.
Î On mounting valve accessories, make
sure that they can be operated from the workplace of the operating personnel.
Note:
The workplace of operating person­nel is the location from which the valve, actuator and any mounted
valve accessories can be accessed to operate them.

Mounting and start-up
5.2.2 Additional ttings
Strainers
We recommend installing a SAMSON strainer upstream of the valve. It prevents sol­id 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 down­stream of the valve and setting up a bypass line. The bypass line ensures that the plant does not need to be shut down for service and repair work on the valve.
Insulation
Only insulate control valves with insulating section or bellows seal up to the bonnet ange of the valve body for medium tem­peratures below 0°C (32°F) and above 220°C (428°F).
Do not insulate valves mounted to comply with NACE MR0175 requirements.
Test connection
Versions with bellows seal tted with a test connection (G
1
/
8
) at the top ange allow the
tightness of the bellows to be monitored. Particularly for liquids and vapors, we rec-
ommend installing a suitable leakage indica­tor (e.g. a contact pressure gauge, an outlet to an open vessel or an inspection glass).
WARNING!
Risk of personal injury due to compo­nents under pressure and process
medium escaping under pressure. Do not loosen the screw of the test
connection while the valve is in oper-
ation.
Safety guard
To reduce the crush hazard arising from moving parts (actuator and plug stem), a safety guard can be installed.
Noise emission
Trims with ow dividers can be used to re­duce noise emission (see uT8081).
5.2.3 Installing the control valve
Version with anges
1. Close the shut-off valve in the pipeline
while the valve is being installed.
2. Remove the protective caps from the
valve ports before installing the valve.
3. Lift the valve using suitable lifting equip-
ment to the site of installation (see sec­tion4.2.2). Observe the ow direction through the valve. The arrow on the valve indicates the direction of ow.
4. Make sure that the correct ange gaskets
are used.
5. Bolt the pipe to the valve free of stress.
Page 34
34 EB 8012 EN
Mounting and start-up
6. Depending on the eld of application, allow the valve to cool down or heat up to reach ambient temperature before start up.
7. Slowly open the shut-off valve in the pipeline after the valve has been in­stalled.
NOTICE
Risk of valve damage due to a sud­den pressure increase and resulting
high ow velocities.
Slowly open the shut-off valve in the
pipeline during start‑up.
8. Check the valve to ensure it functions properly.
Version with welding ends
1. Proceed as described for “Version with anges” (steps 1 to 3).
2. Completely retract the actuator stem to protect the plug from sparks during weld­ing.
3. Weld the valve free of stress into the pipeline.
4. Proceed as described for “Version with anges” (steps 6 to 8).
5.3 Quick check
SAMSON valves are delivered ready for use. To test the valve's ability to function, the following quick checks can be performed:
Tight shut-off
1. Close the valve.
2. Slowly open the shut-off valve in the pipeline.
NOTICE
Risk of valve damage due to a sud­den pressure increase and resulting
high ow velocities.
Slowly open the shut-off valve in the
pipeline during start‑up.
3. Check the valve for leakage to the atmo­sphere (visual inspection).
Travel motion
The movement of the actuator stem must be linear and smooth.
Î Open and close the valve, observing the
movement of the actuator stem.
Î Apply the maximum and minimum con-
trol signals to check the end positions of the valve.
Î Check the travel reading at the travel in-
dicator scale.
Page 35
EB 8012 EN 35
Mounting and start-up
Fail-safe position
Î Shut off the signal pressure line. Î Check whether the valve moves to the
fail-safe position.
Adjustable packing
Tip:
A label on the ange (2) or yoke (3) indicates whether an adjustable packing is installed.
1. Tighten the threaded bushing gradually (by turning it clockwise) until the packing seals the valve.
NOTICE
Risk of valve damage due to the
threaded bushing tightened too far.
Make sure that the plug stem can still move smoothly after the threaded
bushing has been tightened.
2. Open and close the valve several times.
3. Check the valve for leakage to the atmo­sphere (visual inspection).
4. Repeat steps 1 and 2 until the packing completely seals the valve.
Note:
If the adjustable packing does not seal properly, contact SAMSON's After‑sales Service department.
Pressure test
During the pressure test, make sure the fol­lowing conditions are met:
− Retract the plug stem to open the valve.
− Observe the maximum permissible pres-
sure for valve and plant.

Maintenance
7 Maintenance
The control valve is subject to normal wear, especially at the seat, plug, and packing. Depending on the operating conditions, check the valve at regular intervals to pre­vent possible failure before it can occur.
Tip:
SAMSON's After‑sales Service de­partment can support you to draw up
a maintenance plan for your plant.
We recommend removing the valve from the pipeline or service or repair work (see sec­tion9.2).
DANGER!
Risk of bursting in pressure equip­ment. Control valves and pipelines are pressure equipment. Improper open­ing can lead to bursting of the valve.
− Before starting any work on the control valve, depressurize all plant
sections concerned and the valve.
− Drain the process medium from all the plant sections concerned as well
as the valve.
− Wear personal protective equip- ment.
WARNING!
Risk of personal injury due to resid-
ual process medium in the valve.
While working on the valve, residual process medium can escape and, de-
pending on its properties, may lead
to personal injury, e.g. (chemical) burns.
Wear protective clothing, gloves, and
eyewear.
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.

DANGER!
Risk of bursting in pressure equip­ment. Control valves and pipelines are pressure equipment. Improper open­ing can lead to bursting of the valve.
− Before starting any work on the control valve, depressurize all plant
sections concerned and the valve.
− Drain the process medium from all the plant sections concerned as well
as the valve.
− Wear personal protective equip- ment.
WARNING!
Risk of personal injury due to resid-
ual 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.
Wear protective clothing, gloves, and
eyewear.
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.
− Allow components and pipelines to
cool down or heat up.
− Wear protective clothing and
gloves.
9.1 Decommissioning
To decommission the control valve for service and repair work or disassembly, proceed as follows:
1. Close the shut-off valves upstream and downstream of the control valve to stop the process medium from owing through the valve.
2. Completely drain the pipelines and valve.
3. Disconnect and lock the pneumatic air supply to depressurize the actuator.
4. If necessary, allow the pipeline and valve components to cool down or heat up.
9.2 Removing the valve from
the pipeline
Version with anges
1. Put the control valve out of operation (see section9.1).
2. Unbolt the ange joint.
