Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type3323 Three-way Valve in combination with an actuator (e.g. Type3372
Electropneumatic Actuator, Type3371 Pneumatic Actuator, Type5824, Type5827 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, opera-
tors must ensure that the control valve is only used in operating conditions that meet the spec-
i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.

1-2 EB 8113/8114 EN
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, e.g. when working at height
− Safety footwear, if applicable ESD (electrostatic discharge) footwear
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). The fail-safe action of the actua-
tor (see the 'Design and principle of operation') 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 operat-
ing pressure, the signal pressure or by moving parts by taking appropriate precautions. Plant
operators and operating personnel must observe all hazard statements, warnings and cau-
tion 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 8113/8114 EN 1-3
Safety instructions and measures
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.
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, 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 decla-
ration of conformity, which includes information about the applied conformity assessment
procedure. The 'Certicates' section 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 the
scope of Directive 2014/34/EU.
ÎFor connection to the equipotential bonding system, observe the requirements specied in
Clause6.4 of EN60079-14 (VDE0165-1).

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.

Safety instructions and measures
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 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 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.
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).

1-6 EB 8113/8114 EN
Safety instructions and measures
WARNING
!
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.
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.

EB 8113/8114 EN 1-7
Safety instructions and measures
WARNING
!
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 (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).

3 Design and principle of oper-
ation
Depending on the plug arrangement, the
Type3323 Three-way Valve can be used ei-
ther as a mixing or diverting valve. The de-
sign of the mixing and diverting valves in
sizes DN15 to 25 (NPS½ to 1) is identical.
The Type3323 Valve is preferably to be
combined with the following SAMSON actu-
ators:
− Type3372 Electropneumatic Actuator
− Type3371 Pneumatic Actuator
− Type3374 Electric Actuator
− Type5824 or Type5827 Electric Actua-
tor
The two seats and two plugs with plug stem
are installed in the body. The plug stem is
connected to the actuator stem by a stem
connector and sealed by the spring-loaded
packing.
The medium ows through the valve in the
direction indicated by the arrow.
In mixing valves, the process media to be
mixed enter at valve ports Aand B. The
combined ow exits the valve at port AB (see
Fig.3-2).
In diverting valves, the process medium en-
ters at the valve port AB and the partial
ows exit at ports Aand B (see Fig.3-1).

Design and principle of operation
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
associated actuator documentation). The fail-
safe action of SAMSON actuators is
specied on the actuator nameplate.
Upon failure of the air supply or supply volt-
age, the valve tted with the corresponding
actuator moves to one of the following fail-
safe positions.
Actuator stem extends (FA)
When the supply air or supply voltage fails,
port B is closed in mixing valves and port A
is closed in diverting valves.
PortB of diverting valves in sizes DN15 to
25/NPS½ to 1 is closed as these valves
have the same construction as mixing valves.
Actuator stem retracts (FE)
When the supply air or supply voltage fails,
port A is closed in mixing valves and port B
is closed in diverting valves.
PortA of diverting valves in sizes DN15 to
25/NPS½ to 1 is closed as these valves
have the same construction as mixing valves.
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.

Tip
The ow rate from ports A or B to AB and
vice versa depends on the cross-sectional
area of ow between the seats and plugs.
The plugs are moved by changing the control
signal applied to the actuator.

Design and principle of operation
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.
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.

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 Sheets
uT8113 and uT8114.
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 3-3.
The dimensions and weights for the ANSI
versions are listed in Table 3-4.
