Safety instructions and measures

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 flow rate, pressure or temperatureof liquids, 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.
Welding operations are to be performed only by personnel who has the necessary qualification to perform the applied welding procedure and handle the materials used.
Explosion-protected versions of this device must be operated only by personnel who has undergone special training or instructions or who is authorized to work on explosion-protected
devices in hazardous areas.

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 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 witha SAMSON Type 3271 or Type 3277 Pneumatic Actuator, the valve moves to a certain failsafe position (see the 'Design and principle of operation' chapter) upon supply air or control
signal failure. The fail-safe action of the actuator is the same as its direction of action and isspecified 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.
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.

Safety instructions and measures

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.
Non-electric control valve versions whose bodies are not lined with an insulating material
coating do not have their own potential ignition source according to the hazard assessment
stipulated in Clause 5.2 of ISO 80079-36, even in the rare incident of an operating fault.
Therefore, such valve versions do not fall within the scope of Directive 2014/34/EU.

EB 8012 EN

Design and principle of operation

3 Design and principle of operation
See Fig. 3-1 and Fig. 3-2 on page 3-2.
The Type 3241 Valve is a single-seatedglobe valve. This valve is preferably combined with a SAMSON Type 3271 or
Type 3277 Pneumatic Actuator. It can also
be combined with other actuators.
The seat (4) and plug with plug stem (5) areinstalled in the body (1). In some versions,the seat is already integrated into the body.
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 theselected fail-safe action. 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 flows through the valve in the
direction indicated by the arrow. A rise insignal 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 flow rate through the valve.
Tip
We recommend the use of positioners withintegrated diagnostic firmware (see Chapter 3.4) for valves used for on/off service.
The partial stroke test included in this soft-

EB 8012 EN

ware helps prevent a shut-off valve normallyin its end position from seizing up or getting
jammed.

3.1 Fail-safe action
The fail-safe position of the control valve upon air supply or control signal failure depends on the actuator used (see associatedactuator documentation).
Depending on how the compression springs
are arranged in the SAMSON Type 3271
and Type 3277 Pneumatic Actuator, thevalve has one of two different fail-safe positions:− Actuator stem extends (FA)When the signal pressure is reduced or
the air supply fails, the springs move theactuator stem downward and close thevalve. 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 theactuator stem upwards and open thevalve. 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

The pneumatic actuator (with or without
handwheel) can be replaced by anotherpneumatic actuator in a different size, butwith the same travel.
Î Observe the maximum permissible actuator force.
Note
If the travel range of the actuator is larger
than the travel range of the valve, the springassembly in the actuator must be preloadedso 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(see Information Sheet u T 8300).

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.

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

3.4 Valve accessories

Insulation
Control valves can be insulated to reduceheat energy transfer.
Refer to the instructions in the 'Installation'
chapter.
Test connection
Versions with bellows seal fitted with a test
connection (G 1/8) at the top flange allow thesealing ability of the bellows to be monitored.
Particularly for liquids and vapors, we recommend installing a suitable leakage indicator (e.g. a contact pressure gauge, an outlet
to an open vessel or an inspection glass).
Safety guard
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

qualified to carry out such tasks.

4.1 Accepting the delivered
goods
After receiving the shipment, proceed as follows:
1. Check the scope of delivery. Check thatthe specifications on the valve nameplatematch the specifications in the delivery
note. See the 'Markings on the device'chapter for nameplate details.
2. Check the shipment for transportation
damage. Report any damage to SAMSON and the forwarding agent (refer todelivery note).
3. Determine the weight and dimensions of
the units to be lifted and transported inorder to select the appropriate lifting
equipment and lifting accessories. Referto the transport documents and the 'Technical data' chapter.

4.2 Removing the packaging
from the valve

Î Leave the control valve in its transport
container or on the pallet to transport iton site.
Î Do not remove the protective caps fromthe inlet and outlet until immediately before installing the valve into the pipeline.
They prevent foreign particles from entering the valve.
Î Dispose and recycle the packaging in accordance with the local regulations.

4.3 Transporting and lifting thevalve! DANGER
Danger due to suspended loads falling.
Î Stay clear of suspended or moving
loads.
Î Close off and secure the transport paths.
! WARNING
Risk of lifting equipment tipping over andrisk of damage to lifting accessories due toexceeding the rated lifting capacity.
Î Only use approved lifting equipment andaccessories whose minimum lifting capacity is higher than the weight of thevalve (including actuator and packaging,
if applicable).

Observe the following sequence:Î Do not open or remove the packaging
until immediately before lifting to installthe valve into the pipeline.

EB 8012 EN

4-1

Shipment and on-site transport! WARNING
Risk of personal injury due to the control
valve tipping over.
Î Observe the valve's center of gravity.
Î Secure the valve against tipping over orturning.
! WARNING
Risk of injury due to incorrect lifting without
the use of lifting equipment.
Lifting the control valve without the use of lifting equipment may lead to injuries (back injury in particular) depending on the weightof the control valve.
Î Observe the occupational health andsafety regulations valid in the country ofuse.
! NOTICE
Risk of valve damage due to incorrectly attached slings.
The lifting eyelet/eyebolt on SAMSON actuators is only intended for mounting and removing the actuator as well as lifting the actuator without valve. Do not use this lashingpoint to lift the entire control valve assembly.
Î When lifting the control valve, make surethat the slings attached to the valve bodybear the entire load.
Î Do not attach load-bearing slings to theactuator, handwheel or any other parts.
Î Observe lifting instructions (see Chapter 4.3.2).

Tip
A swivel hoist can be screwed into SAMSON actuators with a female thread on the
top diaphragm case in place of the eyebolt(see associated actuator documentation).
In contrast to the lifting eyelet/eyebolt, theswivel hoist is designed for setting a control
valve assembly upright.
The sling between the swivel hoist and rigging equipment (hook, shackle etc.) must notbear any load when lifting a control valve
assembly. The sling only protects the control
valve from tilting while being lifted.
Tip
Our after-sales service can provide more detailed transport and lifting instructions on request.

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.

The plant engineering company is responsible for selecting and implementing a suitablesupport or suspension of the installed control
valve and the pipeline.

To ensure that the valve functions properly,
proceed as follows:Î Observe the inlet and outlet lengths (seeTable 5-1). Contact SAMSON if thevalve conditions or states of 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 “Support or suspension” in thischapter.
Î Install the valve allowing sufficient space
to remove the actuator and valve or toperform service work on them.
Mounting position
Generally, SAMSON recommends installingthe valve with the actuator upright and on
top of the valve.
In the following versions/applications, thevalve must be installed with the actuator on
top:− Valves in NPS 4 and larger− Valves with insulating section or bellows
seal for low temperatures below –10 °C(14 °F)

5-2

Note

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.
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.
Valve accessoriesÎ During connection of valve accessories,
make sure that they are easily accessible
and can be operated safely from thework position.

Installation! WARNING
Risk of personal injury due to incorrect removal of the anti-rotation fixture under tension.
Once the actuator has been mounted on thevalve and the assembly is ready for use, theclamps (301) of the anti-rotation fixture on
the plug stem are under tension.
Î Follow the instructions in this document
during mounting or removal.
Î Do not loosen the screws (303) of the anti-rotation fixture while the force generated by the supply air and/or the actuator
springs is transmitted to the actuator stemand the stem (9).
Î First remove the actuator from the valve
or ensure it cannot transmit any forces tothe actuator stem before removing theanti-rotation fixture on the plug stem.
Depending on the version, SAMSON control
valves are either delivered with the actuator
already mounted on the valve or the valve
and actuator are delivered separately. Whendelivered separately, the valve and actuator
must be assembled together on site.
Versions with V-port plugTo achieve the best flow conditions inside thevalve, the V-port plug must always be installed with the port that releases the flow
first when the valve opens facing toward thevalve outlet. This is the largest of the three
V-shaped ports (see Fig. 5-5).
Î Before mounting the actuator, determine
which V-shaped port is uncovered firstwhen the plug is lifted out of the seat.

5-10

Î On mounting the actuator, make surethat the V-shaped port uncovered firstfaces toward the valve outlet.

9.1 Periodic testing
Depending on the operating conditions,check the valve at certain intervals to prevent
possible failure before it can occur. Plant operators are responsible for drawing up an
inspection and test plan.

Tip
Our after-sales service can support you in
drawing up an inspection and test plan foryour plant.

SAMSON recommends the following inspections and tests:
Inspection and testing

Recommended action to be taken in the event of anegative result

Check the markings, labels andnameplates on the valve for theirreadability and completeness.

Immediately renew damaged, missing or incorrect
nameplates or labels.
Clean any inscriptions that are covered with dirt and are
illegible.

Check the valve for external damage
Repair any damage immediately. If necessary, put thethat could impair the proper functioning control valve out of operation (see the 'Decommissioning'of the control valve or even its safe
chapter).
operation.
Check the valve accessories to ensure
they are mounted properly.

Tighten the connections of the valve accessories.

Seat leakage 1) (see Fig. 9-1)
(without testing to check that theleakage 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) 1):
Inspect the control valve at the possible
points of leakage to ensure there is noleakage (see Fig. 9-1).

Check flanged joints (tightening torques).

Versions with bellows seal:
WARNING! Risk of personal injury due
to pressurized components and as aresult of process medium being
discharged.
Do not loosen the screw of the test
connection while the valve ispressurized.

Version with adjustable packing 2): adjust the packing (seesection 'Adjusting the packing' in the 'Installation' chapter >'Testing the installed valve') or replace the packing. To
replace the packing, put the control valve out of operation(see the 'Decommissioning' chapter).

9-4

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

If the bellows seal is defective, put the control valve out of
operation (see the 'Decommissioning' chapter). To repair
the bellows seal, contact our after-sales service (see the'Repairs' chapter).

Inspection and testing

Recommended action to be taken in the event of anegative result

Check to ensure that the actuator andplug stem move smoothly.

Version with adjustable packing 2): tighten the packing
correctly (see section 'Adjusting the packing' in the'Installation' chapter > 'Testing the installed valve').
If the actuator and plug stem is blocked, put the control
valve out of operation (see the 'Decommissioning' chapter)and remove 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 thecontrol signal. Before unblocking the actuator, release any
stored energy in the actuator (e.g. spring compression). See
associated actuator documentation.
SAMSON recommends the use of positioners withintegrated diagnostic firmware for valves used for on/off
service. The partial stroke test included in this software
helps prevent a shut-off valve normally in its end position
from seizing up or getting jammed.

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

2)

Put the control valve out of operation (see the'Decommissioning' chapter). Identify the cause for the
malfunction and rectify it (see the 'Troubleshooting'chapter).

EXPERTplus valve diagnostics can help identify external leakage at dynamic sealing systems as well
as seat leakage in valve versions without balanced plugs while the valve is in use. EXPERTplus comesas standard in the digital positioners (Type 3730, TROVIS 3730, Type 3731, TROVIS 3793,
