1 Safety instructions and measures
Intended use
The SAMSON Type 3251 or Type 3251-AM Globe Valve in combination with an actuator
(e.g. Type 3271 or Type 3277 Pneumatic Actuator) is designed to regulate the flow rate,
pressure or temperature of liquids, gases or vapors.
Only the Type 3251 Valve can be used after prior consultation and sizing for special appli-
cations, such as oxygen, chlorine, phosgene, hydrogen sulfide (NACE), hydrogen or molten
salt service. The Type 3251-AM Valve cannot be used for such applications. The
Type 3251-AM Valve is also not suitable for pressure swing adsorption (PSA) applications. In
this case, the Type 3251 Valve can be used.
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 operating conditions that meet the specifications 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 specified, 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 fields of application as well as
possible uses.
Reasonably foreseeable misuse
The control valve is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
− Use outside the limits defined 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
Qualifications of operating personnel
The control valve must be mounted, started up, serviced and repaired by fully trained and
qualified 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
EB 8052 EN 1-1
