1 Safety instructions and measures
Intended use
The SAMSON Type3321CT Globe Valve in combination with an actuator (e.g. Type3379
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 dened 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 specications used for sizing the
valve at the ordering stage. In case operators intend to use the control valve in other applica-
tions or conditions than specied, 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 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 dened during sizing and by the technical data
− Use outside the limits dened 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
Qualications of operating personnel
The control valve must be mounted, started up, serviced and repaired by fully trained and
qualied 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 checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substance database).
Î Provide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-
cess medium used.
Î Wear hearing protection when working near the valve.
Î Check with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications 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 devices
Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec-
tion3.1). The fail-safe action of the actuator is the same as its direction of action and is specied 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 service work.
We also recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substance database).
Î Observe safety measures for handling the device.
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, the operator must ensure that operating personnel or third persons are not exposed to any danger.

EB 8115 EN 7
Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the specied hazard statements, warnings
and caution notes. Furthermore, the operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards and regulations
The control valves comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. Valves with a CE marking have an EU declaration of conformity, which
includes information about the applied conformity assessment procedure. This EU declaration
of conformity is included in the Appendix of these instructions (see section10.2).
According to the ignition risk assessment performed in accordance with EN13463-1:2009,
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.
Î For connection to the equipotential bonding system, observe the requirements specied in
section 6.4 of EN60079-14 (VDE0165 Part 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. Improper opening can lead to valve
components bursting.
Î Before starting any work on the valve, depressurize all plant sections concerned as
well as the valve.
Î Drain the process medium from all the plant sections concerned as well as the
valve.
Î Wear personal protective equipment.
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 ngers into the yoke while the valve is in operation.
Î While working on the control valve, disconnect and lock the pneumatic air supply.
Risk of personal injury when the pneumatic 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 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, safety gloves, and eyewear.

Design and principle of operation
3 Design and principle of oper-
ation
The single-seated Type3321CT Globe Valve
is preferably combined with a SAMSON
Type3379 Pneumatic Actuator.
The seat (2) and plug with plug stem (3) are
installed in the body (1). The plug stem has a
thread to screw it onto the actuator stem and
is sealed by the spring-loaded packing (8).
The process medium ows through the valve
in the direction indicated by the arrow in the
ow-to-open direction. The plug position determines 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
Depending on how the compression springs
are arranged in the pneumatic actuator, the
valve has two fail-safe positions that become
effective when the supply air fails:
− Fail-close: the valve is closed upon air
supply failure.
− Fail-open: the valve is opened upon air
supply failure.

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
Table3). Contact SAMSON if the valve
conditions or state 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 sufcient 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.
Î Contact SAMSON if the mounting posi-
tion is not as specied above.
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.
Premature wear and leakage due to insufcient support or suspension.
In the following versions, the control valve
must be supported or suspended:
− Valves that are not installed with the actua-
tor in the upright position on top of the
valve.
Attach a suitable support or suspension to
the valve.
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.
The workplace of operating personnel is the
location from which the valve, actuator and
any mounted valve accessories can be accessed to operate them.
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 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.
5.2.3 Installing the control
valve
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 sec-
tion4.2.2). Observe the ow direction

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.
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 (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.
Fail-safe position
Î Shut off the signal pressure line.
Î Check whether the valve moves to the
fail-safe position.
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.
The plant operator is responsible for
performing the pressure test. SAMSON's
After-sales Service department can support
you to plan and perform a pressure test for
your plant.

Servicing
7 Servicing
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.
SAMSON's After-sales Service department
can support you in drawing up an inspection
and test plan for your plant.
We recommend removing the valve from the
pipeline for service or repair work (see sec-
tion9.2).
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equipment. Improper opening can lead to bursting
of the valve.
− Before starting any work on the valve, de-
pressurize all plant sections concerned as
well as the valve.
− Drain the process medium from all the
plant sections concerned as well as the
valve.
− Wear personal protective equipment.
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.
Wear protective clothing, safety gloves, and
eyewear.
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 safety gloves.
Risk of valve damage due to incorrect servicing or repair.
Service and repair work must only be
performed by trained staff.
Risk of valve damage due to excessively high
or low tightening torques.
Observe the specied 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 specied tightening torques
(uAB0100).
Risk of valve damage due to the use of unsuitable tools.
Only use tools approved by SAMSON
(uAB0100).
