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 defined 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 specifications used for sizing the valve at
the ordering stage. In case operators intend to use the control valve in other applications or
conditions than specified, 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.

Refer to the technical data and nameplate for limits and fields of application as well as
