Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type3349 Angle Valve in combination with an actuator (e.g. Type3271,
Type3277 or Type3379 Pneumatic Actuator) is designed to regulate the ow rate, pressure
or temperature of liquids, gases or vapors. The angle valve is suitable for use in aseptic ap-
plications (e.g. in the pharmaceutical and food industries).
The valve with its actuator is designed to operate under exactly dened conditions (e.g. oper-
ating pressure, process medium, temperature). Therefore, operators must ensure that the con-
trol 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 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.
Welding operations must only be performed by personnel who has the necessary qualica-
tion to perform the applied welding procedure and handle the materials used.

1-2 EB 8048-2 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 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
a SAMSON Type3271 or Type3277 Pneumatic Actuator or the Type3379 Pneumatic Piston
Actuator, the valve moves to a certain fail-safe position (see the 'Design and principle of op-
eration' section) upon supply air or control signal failure. The fail-safe action of the actuator
is the same as its direction of action and is specied on the nameplate of SAMSON actua-
tors.
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, 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 8048-2 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 meet the requirements in the Regulation (EC) No.1935/2004 for materi-
als and articles intended to come into contact with food
The control valves comply with the requirements of the European Pressure Equipment Direc-
tive 2014/68/EU and the Machinery Directive 2006/42/EC. 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 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).

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 open-
ing 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.
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.
While the valve is operating, air is vented from the actuator, for example, during
closed-loop operation 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.

1-6 EB 8048-2 EN
Safety instructions and measures
WARNING
!
Crush hazard arising from moving parts.
The pneumatic control valves with Type3271 and Type3277 Actuator contain 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 air supply is connected to the
actuator.
ÎBefore working on the control valve, disconnect and lock the pneumatic air supply
as well as the control signal.
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 preloaded springs.
Valves in combination with pneumatic actuators with preloaded springs are under ten-
sion. These control valves with SAMSON Type3271 or Type3277 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).
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.
Risk of personal injury due to pressurized components and process medium being
discharged.
ÎDo not loosen the screw of the test connection while the valve is pressurized.

EB 8048-2 EN 1-7
Safety instructions and measures
WARNING
!
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.
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

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.

1-8 EB 8048-2 EN
Safety instructions and measures
NOTICE
!
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 (see the 'Tightening torques' section in An-
nex).
Risk of valve damage due to the use of unsuitable tools.
Certain tools are required to work on the valve.

Design and principle of operation
3 Design and principle of oper-
ation
The Type3349 Angle Valve is preferably
combined with a SAMSON Type3271 or
Type3277 Pneumatic Actuator (see Fig.3-1)
as well as the Type3379 Pneumatic Piston
Actuator (see Fig.3-2). The valve comes with
welding ends as standard. The valve is suit-
able for aseptic applications and is designed
without any cavities.
The process medium preferably ows
through the valve in the ow-to-open (FTO)
direction 1). The ow-to-close direction
(FTC)2) is possible. The process medium al-
ways ows through the micro-ow valve ver-
sion in the ow-to-close (FTC) direction. The
ow direction is indicated by an arrow on
the valve body. The position of the valve
plug determines the ow rate across the
cross-sectional area of ow released be-
tween the plug and lathed seat.
The plug stem is sealed by a full PTFE dia-
phragm that is USP ClassVI certied. A
packing can additionally be used in the mi-
cro-ow valve version.
The test connection allows the diaphragm to
be monitored for leakage. In the version with
backup packing, the test connection is sealed
by a stopper. The stopper must be replaced
with a suitable leakage indicator (e.g. a con-
tact pressure gauge, an outlet to an open
vessel or an inspection glass) when the valve
is installed. The test connection of valves
without a backup packing is tted with a
pipe elbow to allow the safe drainage of any
medium that escapes.
When combined with the Type3271 or
Type3277 Actuator, the actuator stem and
plug stem are connected using stem connec-
tor clamps (A26/27). When combined with
the Type3379 Actuator, the actuator stem
and plug stem are screwed together.
We recommend the use of positioners with
integrated diagnostic rmware (see sec-
tion3.4) for valves used for on/off service.
The partial stroke test included in this soft-
ware helps prevent a shut-off valve normally
in its end position from seizing up or getting
jammed.
