Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type3259 Angle Valve in combination with an actuator (e.g. Type3271 or
Type3277 Pneumatic Actuator) is designed to regulate the ow rate, pressure or temperature
of liquids, gases or vapors in industrial high-pressure plants according to the IG standard.
The valve with its actuator is designed to operate under exactly dened conditions (e.g.
operating pressure, process medium, temperature). Therefore, operators must ensure that the
control 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
applications or conditions than specied, 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 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. 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.

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).
ÎProvide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-
cess medium used.
ÎWear hearing protection when working near the valve.
ÎCheck 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 spec-
ied 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 service work.
We also recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substance database).
ÎObserve safety measures for handling the device as well as re prevention and explosion
protection measures.
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 ex-
posed to any danger.
EB 8059 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 Direc-
tive 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.
ÎFor connection to the equipotential bonding system, observe the requirements specied in
section 6.4 of EN60079-14 (VDE0165 Part 1).
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
−Mounting and operating instructions for mounted actuator, e.g. uEB8310-X for
Type3271 and Type3277 Actuators
−Mounting and operating instructions for mounted valve accessories (positioner, solenoid
valve etc.)
−uAB0100 for tools, tightening torques and lubricant

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.
ÎBefore starting any work on the valve, depressurize all plant sections concerned as
well as the valve.
ÎDrain the process medium from all the plant sections concerned as well as the
valve.
ÎWear 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.
ÎDo not insert hands or ngers 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 actuator vents.
While the valve is operating, the actuator may vent during closed-loop control 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.
EB 8059 EN 9
Safety instructions and measures
WARNING
!
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 identied 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 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, safety 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 safety gloves.
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.
ÎObserve the maximum permissible pressure for valve and plant.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for a process medium with dened properties.
ÎOnly use the process medium specied for sizing.
