Intended use
The SAMSON Type 41-73 Regulator is an excess pressure valve. It consists of a Type 2417
Valve and a Type 2413 Actuator. The valve and actuator are delivered separately and must
be assembled according to the instructions in this document.
The self-operated regulator is used to control the upstream pressure p
1
in the pipeline to the
adjusted set point. Liquids, gases and vapors in processing and industrial plants can be con-
trolled 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.
