Intended use
The SAMSON Type 33-7 Regulator is a safety excess pressure valve (SEV).
The self-operated regulator is used to control the upstream pressure p

in the pipeline to the
adjusted set point. Liquids and gases in processing and industrial plants can be controlled by
the regulator.
The regulator is designed to operate under exactly defined conditions (e.g. operating
pressure, 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 regulator 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.
