Intended use
The SAMSON Type 2357-3 Pressure Regulator is designed to keep the pressure (either
downstream pressure p
2
or upstream pressure P
1
, depending on the version) constant to the
adjusted set point, especially in cryogenic plants. Liquids, gases and vapors in processing
and industrial plants can be controlled by the regulator.
The regulators are designed to operate under exactly defined conditions (e.g. operating pres
-
sure, process medium, temperature). Therefore, operators must ensure that the regulators are
only used in operating conditions that meet the specifications used for sizing the devices at
the ordering stage. In case operators intend to use the regulators in other applications or
conditions than 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.
