1 Safety instructions and measures
Intended use
The SAMSON Type 2404-2 Regulator is an excess pressure valve with pilot valve for small
set point ranges. It consists of a Type 2406 Valve (DN 65 to 150) or Type 2422 Valve as the
main valve with a Type 2420 Diaphragm Actuator (DN 200 to 400), Type 2406 Pilot Valve
and the Type 2441 Input Pressure Regulator. The assembled unit is tested before delivery.
The self-operated regulator is used to control the pressure in storage tanks. Gases in process-
ing and industrial plants can be controlled by the regulator.
The regulator is designed to operate under exactly defined conditions (e.g. operating pres-
sure, process medium, temperature). Therefore, operators must ensure that the regulator is
only used in operating conditions that meet the specifications used for sizing the regulator at
the ordering stage. In case operators intend to use the controllers in applications or condi-
tions 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 regulator 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 additional fittings mounted on the regulator
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 regulator must be mounted, started up, serviced and repaired by fully trained and quali-
fied personnel only; the accepted industry codes and practices must 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 spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
