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 an electric control valve: Type3222/5857, Type3222/5824, Type3222/5825,
Type3222/5827, Type3222/5757-3, Type3222/5757-7, Type3222/5724-3,
Type3222/5724-8, Type3222/5725-3 and Type3222/5725-8
− As a 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 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 applications
or conditions other than those 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.
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 dened during sizing and by the technical data
− Type3222/2780 Control Valve: Use outside the limits dened by the valve accessories
connected to the 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
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 must 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
