Safety instructions and measures
1 Safety instructions and measures
Intended use
The Type3275A Pneumatic Piston Actuator is designed for operating a mounted globe valve.
In combination with the valve, the actuator is used to shut off and control the ow of liquids,
gases or vapors in the pipeline. The actuator is mainly used in combination with PSA valves1)
(e.g. SAMSON Type3241-PSA Valve).
The actuator is designed to operate under exactly dened conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuator is only used in operating conditions that
meet the specications used for sizing the actuator at the ordering stage. In case operators
intend to use the actuator in other applications or conditions than 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 actuator 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 accessories connected to the actuator
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 actuator 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. 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 spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.

Safety instructions and measures
Personal protective equipment
We recommend wearing the following personal protective equipment when handling the
Type3275A Pneumatic Actuator:
− Protective gloves and safety footwear when mounting or removing the actuator
− Eye protection and hearing protection while the actuator is operating.
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 Type3275A Actuator does not have any special safety features.
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 actuator by the signal pressure or 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.
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.
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.

EB 8314-1 EN 1-3
Safety instructions and measures
Referenced standards, directives and regulations
According to the ignition risk assessment performed in accordance with Clause5.2 of
ISO80079-36, the non-electrical actuators 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).
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
− Mounting and operating instructions for the valve on which it is mounted
− Mounting and operating instructions for mounted valve accessories (positioner, solenoid
valve etc.)
− uAB0100 for tools, tightening torques and lubricant

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of bursting in the actuator.
Actuators are pressurized. Improper opening can lead to actuator components burst-
ing.
ÎBefore starting any work on the actuator, depressurize all plant sections affected
and the actuator.
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The actuator contains moving parts (actuator stem), which can injure hands or ngers if
inserted into the actuator.
ÎDo not insert hands or nger into the yoke while the air supply is connected to the
actuator.
ÎWhile working on the actuator, disconnect and lock the pneumatic air supply as well
as the control signal.
ÎDo not impede the movement of the actuator stem by inserting objects into the yoke.
Risk of personal injury when the actuator vents.
The actuator is operated with air. As a result, air is vented during operation.
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 and hearing protection when working near the actuator.

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 actuator being illegible.
Over time, markings, labels and nameplates on the actuator 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 actuator damage due to excessively high or low tightening torques.
Observe the specied torques when tightening actuator components. Excessive tighten-
ing torques lead to parts wearing out more quickly. Parts that are not tightened far
enough may loosen.
ÎObserve the specied tightening torques (uAB0100).
Risk of actuator damage due to the use of unsuitable tools.
Certain tools are required to work on the actuator.
ÎOnly use tools approved by SAMSON (uAB0100).

1-6 EB 8314-1 EN
Safety instructions and measures
NOTICE
!
Risk of actuator damage due to the use of unsuitable lubricants.
The lubricants to be used depend on the actuator material. Unsuitable lubricants may
corrode and damage surfaces.
ÎOnly use lubricants approved by SAMSON (uAB0100).
1.4 Warnings on the device
Warning Meaning of the warning Location on the device
Warning against the incorrect use of the eyebolt
on the actuator housing.
Only attach load-bearing slings to them to verti-
cally lift the actuator on its own (without the valve).
The eyebolt must not be used to vertically lift the
entire control valve assembly.
