Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type3222 Valve is designed for use in temperature control circuits in HVAC
plants (e.g. for DHW heating). The valve is primarily combined with the following SAMSON
actuators:
−As electric control valve: Type3222/5857, Type3222/5824, Type3222/5825,
Type3222/5757-3, Type3222/5757-7, Type3222/5724-3, Type3222/5724-8,
Type3222/5725-3, Type3222/5725-7 and Type3222/5725-8
−As pneumatic control valve: Type3222/2780
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 applications 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, SAMSON must be contacted.
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 dened during sizing and in the technical data
−For Type3222/2780 Control Valve: use outside the limits dened by the valve accesso-
ries 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
6 EB 5866 EN
Safety instructions and measures
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.
Personal protective equipment
We recommend wearing the following protective equipment:
−Protective clothing and gloves in applications with hot or cold media
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications 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 features
In combination with the Type5825 Electric Actuator and with the TROVIS5725-3, TRO-
VIS5725-7, and TROVIS5725-8 Electric Actuators with Process Controllers, the following
safety feature exists: upon failure of the power supply, the valve moves to a dened fail-safe
position (see section3.1). The direction of action of the fail-safe action is dened by the actu-
ator version (see associated actuator documentation).
In combination with the Type2780 Pneumatic Actuator, the following safety feature exists:
upon failure of the air supply, the valve moves to a certain fail-safe position (see section3.1).
The fail-safe action corresponds with the direction of action. The fail-safe action of SAMSON
actuators is specied on the actuator nameplate (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.
EB 5866 EN 7
Safety instructions and 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, 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 specied in them. Furthermore, the operating personnel must be familiar with the ap-
plicable 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 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 section10.2).
The electric actuators are designed for use in low voltage installations. For wiring, mainte-
nance, and repair, observe the relevant safety regulations.

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of bursting in pressure equipment.
Control valves and pipelines are pressure equipment. Improper opening can lead to
valve components bursting.
ÎBefore starting any work on the control valve, depressurize all plant sections
concerned and the valve.
ÎDrain the process medium from all the plant sections concerned as well as the
valve.
ÎWear personal protective equipment.
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.
ÎThe electric actuators are protected against spray water (IP54). Avoid jets of water.
EB 5866 EN 9
Safety instructions and measures
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The pneumatic control valve (Type3222/2780) contains moving parts (actuator and
plug stems), which can injure hands or ngers if inserted into the valve.
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 pneumatic actuator (Type2780) 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.
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. burns.
ÎIf possible, drain the process medium from all the plant sections concerned and the
valve.
ÎWear protective clothing and gloves.
Risk of burn injuries due to hot components and pipelines.
Depending on the process medium, valve components, and pipelines may get very hot
and cause burn injuries.
ÎAllow components and pipelines to cool down.
ÎWear protective clothing and gloves.

Safety instructions and measures
1.3 Notes on possible property damage
NOTICE
!
Risk of damage to the electric control valve due to the power supply exceeding the
permissible tolerances.
The electric control valves are designed for use according to regulations for low-volt-
age installations.
ÎObserve the permissible tolerances of the power supply. See associated actuator
documentation.
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant engineering company 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 certain properties (e.g. water, oil,
steam).
ÎOnly use the process medium that meets the specications used for sizing the valve.
