1 Safety instructions and measures

Intended use

The SAMSON Type3222 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: Type3222/5857, Type3222/5824, Type3222/5825,
Type3222/5757-3, Type3222/5757-7, Type3222/5724-3, Type3222/5724-8,
Type3222/5725-3, Type3222/5725-7 and Type3222/5725-8

− As pneumatic control valve: Type3222/2780

The valve with its actuator 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
conditions than specied, 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.

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 dened during sizing and in the technical data

− For Type3222/2780 Control Valve: use outside the limits dened 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

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. 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.

Personal protective equipment

We recommend wearing the following protective equipment:

− Protective clothing and gloves in applications with hot or cold media
Î Check 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. Fur­thermore, the product may no longer meet the requirements for its intended use.

Safety features

In combination with the Type5825 Electric Actuator and with the TROVIS5725-3, TRO­VIS5725-7, and TROVIS5725-8 Electric Actuators with Process Controllers, the following
safety feature exists: upon failure of the power supply, the valve moves to a dened fail-safe
position (see section3.1). The direction of action of the fail-safe action is dened by the actu­ator version (see associated actuator documentation).

In combination with the Type2780 Pneumatic Actuator, the following safety feature exists:
upon failure of the air supply, the valve moves to a certain fail-safe position (see section3.1).
The fail-safe action corresponds with the direction of action. The fail-safe action of SAMSON
actuators is specied 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 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 servicing.

EB 5866 EN 7

Safety instructions and measures

1.2 Notes on possible personal injury

WARNING

!

Crush hazard arising from moving parts.

The pneumatic control valve (Type3222/2780) contains moving parts (actuator and
plug stems), which can injure hands or ngers if inserted into the valve.

Î While 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 (Type2780) 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. burns.

Î If possible, drain the process medium from all the plant sections concerned and the

valve.

Î Wear 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.

Î Allow components and pipelines to cool down.
Î Wear protective clothing and gloves.

Design and principle of operation

3 Design and principle of oper-

ation

The medium ows through the single-seated
globe valve in the direction indicated by the
arrow. The position of the plug determines
the ow rate across the area released be­tween plug (1) and seat (5). The valve is
opened by the valve spring when the actua­tor stem retracts. The plug is moved by
changing the control signal applied to the
actuator. The valve and actuator have a
force-locking connection.

A special version (see Fig.4) is available for
water above 150°C and steam.

3.1 Fail-safe action

When the Type3222 Valve is combined with
one of the following actuators, the valve
moves to the fail-safe position up upon fail­ure of the air supply or power supply:

− Type5825 Electric Actuator

− TROVIS5725-3 and TROVIS5725-7

Electric Actuators with Process Control­lers

− Type 2780 Pneumatic Actuator

The control valve has two different fail-safe
positions:

− Actuator stem extends: upon power sup-
ply or air supply failure, the actuator
stem extends.

The TROVIS5725-3, TROVIS5725-7, and
TROVIS8725-8 Electric Actuators with Pro­cess Controllers in the version with
force-locking attachment and the Type5825
Electric Actuator with "actuator stem ex­tends" fail-safe action are tested by the Ger­man technical surveillance association TÜV
according to DINEN14597 in combination
with the SAMSON Type3222 Valve. The
registration number is available on request.

− Actuator stem retracts: upon power sup-
ply or air supply failure, the actuator
stem retracts.

The fail-safe action of pneumatic actuators
can be reversed (see associated actuator
documentation). The fail-safe action of elec­tric actuators (with process controllers) is al­ready determined at the ordering stage.
