1 Safety instructions and measures
Intended use
The SAMSON Type3321 Globe Valve in combination with an actuator (e.g. Type3372
Electropneumatic Actuator, Type3371 Pneumatic Actuator, Type5824/5825 Electric Actua-
tor, or Type3374 Electric Actuator) is designed to regulate the ow rate, pressure or tem-
perature 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). There-
fore, 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 con-
tacted.
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.
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 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 servicing 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. 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.

6 EB 8111/8112 EN
Safety instructions and measures
Personal protective equipment
We recommend wearing the following protective equipment depending on the process medi-
um:
−Protective clothing, gloves and eyewear in applications with hot, cold, and/or corrosive
media
−Wear hearing protection when working near the valve.
ÎCheck 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. Fur-
thermore, 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 sec-
tion3.1). The fail-safe action of the actuator is the same as its direction of action and is spec-
i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 operat-
ing 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 oper-
ating instructions, especially for installation, start-up, and servicing.
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 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 persons are not ex-
posed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the hazard statements, warning and caution
notes specied in them. Furthermore, the operating personnel must be familiar with the ap-
plicable health, safety and accident prevention regulations and comply with them.

EB 8111/8112 EN 7
Safety instructions and measures
Referenced standards and regulations
The control valves comply with the requirements of the European Pressure Equipment Direc-
tive 2014/68/EU. Valves with a CE marking have a declaration of conformity which in-
cludes 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 2014/34/EU.
ÎFor connection to the equipotential bonding system, observe the requirements specied in
section 6.4 of EN60079-14 (VDE0165 Part 1).

Safety instructions and measures
DANGER
!
Risk of electric shock.
ÎDo not remove any covers to perform adjustment work on live parts.
ÎBefore performing any work on the device and before opening the device, discon-
nect the power supply and protect it against unintentional reconnection.
ÎOnly use power interruption devices that are protected against unintentional recon-
nection of the power supply.
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.
ÎDo not insert hands or nger into the yoke while the valve is in operation.
ÎWhile working on the control valve, disconnect and lock the pneumatic air supply as
well as the control signal.
Risk of personal injury when the pneumatic actuator vents.
While the valve is operating, the Type3371 Actuator may vent during closed-loop con-
trol or when the valve opens or closes.
ÎInstall the control valve in such a way that the actuator does not vent at eye level.
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).

EB 8111/8112 EN 9
Safety instructions and measures
WARNING
!
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.
ÎIf possible, drain the process medium from all the plant sections concerned and the
valve.
ÎWear protective clothing, gloves, and eyewear.
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 heat up.
ÎWear protective clothing and gloves.
1.3 Notes on possible property damage

Safety instructions and measures
NOTICE
!
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 tight-
ened torques lead to parts wearing out quicker. Parts that are too loose may cause leak-
age.
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).
Risk of valve damage due to the use of unsuitable lubricants.

Design and principle of operation
3 Design and principle of oper-
ation
The single-seated Type3321 Globe Valve is
preferably to be combined with the following
SAMSON actuators:
−Type3372 Electropneumatic Actuator
−Type 3371 Pneumatic Actuator
−Type3374 Electric Actuator
−Type5824/5825 Electric Actuator
The seat (4) and plug with plug stem (5) are
assembled in the body (1). The plug stem is
connected to the actuator stem (A3/A7) by a
stem connector (A30/A31) and sealed by
the spring-loaded packing (15).
The process medium ows through the valve
in the direction indicated by the arrow in the
ow-to-open direction. The plug position de-
termines the cross-sectional area between
the seat and plug.
The position of the plug is changed by the
control signal acting on the actuator.

3.1 Fail-safe positions
Upon failure of the air supply or power sup-
ply, the valve moves to its fail-safe position.
−Actuator stem extends (fail-close): upon
power supply or air supply failure, the
actuator stem extends causing the valve
to close.
−Actuator stem retracts (fail-open): upon
power supply or air supply failure, the
actuator stem retracts causing the valve
to open.
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 Mounting types
There are two different types of attachment
to mount the pneumatic or electropneumatic
actuator onto the valve depending on the
version (valve size etc.): mounting using
crossbeam or mounting using rods (see
Table1).
1. Mounting using crossbeam and central
nut
When the actuator is mounted to the
valve using a crossbeam (Form B, Fig.6),
the actuator is fastened to the valve bon-
net using a central nut.
2. Mounting using rods
When the actuator is mounted on rods
(Form C, Fig.7) the actuator is connect-
ed to the valve bonnet using rods. In this
case, a crossbeam is not required for
mounting the actuator. A plate keeps the
correct distance between rods.
When an electric actuator is mounted onto
the valve, it is mounted with a form-t con-
nection using a stem connector and yoke.
