Safety instructions and measures
1 Safety instructions and measures
Intended use
The Type3354 Globe Valve is designed for on/off service in process engineering and plants
with industrial requirements. The valve is suitable for liquids, vapors and gases at tempera-
tures from –10 to +180°C and a nominal pressure of PN16. The globe valve is combined
with a pneumatic piston actuator.
The control valve is designed to operate under exactly dened conditions (e.g. operating
pressure, process medium, temperature). Therefore, 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 con-
ditions than specied, contact SAMSON.
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 by 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 service 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.

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 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 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.
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.
uGESTIS (CLP) hazardous substance database).
ÎObserve safety measures for handling the device as well as re prevention 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.
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.

Safety instructions and measures
Referenced standards and regulations
The devices comply with the requirements of the European Pressure Equipment Directive
2014/68/EU.
Referenced documentation
The mounting and operating instructions of the mounted valve accessories (e.g. uEB8357
for Type4740 Limit Switch) apply in addition to these mounting and operating instructions.
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
!
Risk of personal injury when the actuator vents.
While the valve is operating, the actuator may vent 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.

8 EB 8140 EN
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, 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 dened properties.
ÎOnly use the process medium specied for sizing the valve.
Risk of leakage and valve damage due to excessively high or low tightening
torques.
Observe the specied torques on tightening valve components.
Excessively tightened torques lead to parts wearing out quicker. Parts that are too loose
may cause leakage.
ÎObserve the specied tightening torques (see section7.3).

Design and principle of operation
3 Design and principle of oper-
ation
The pneumatic control valve consists of a
globe (straight-pattern) valve with a soft-
seated plug and a pneumatic piston
actuator.
The medium ows through the valve in the
direction indicated by the arrow. The signal
pressure applied to the piston actuator deter-
mines the position of the plug and thus the
cross-sectional area of ow between the seat
and plug.
The plug/actuator stem (2) is sealed by a
self-adjusting PTFE V-ring packing (4.4) at
