Intended use
The SAMSON Type 42-37 Regulator is a flow and differential pressure regulator.
The SAMSON Type 42-39 Regulator is a flow and differential pressure or pressure regulator.
They consist of a Type 2423 Valve and a Type 2427 Actuator (Type 42-37) or a Type 2429
Actuator (Type 42-39). The valve and actuator (except for tested regulators) are delivered
separately and must be assembled together according to these instructions.
The self-operated regulators are used to control the flow rate and the differential pressure or
pressure in pipelines. 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.
Î
Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.
Reasonably foreseeable misuse
The regulators are 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
Safety features
The Types 42-37 and 42-39 Regulators do not have any special safety features. When re -
lieved of pressure, the regulators are opened by the force of the set point springs.
