Safety instructions and measures

1 Safety instructions and measures
Intended use
The Type 46-7 Flow and Differential Pressure Regulator with additional pressure control actu-
ator is designed for the flow rate and differential pressure control of liquids up to 150 °C.
The additional pressure control actuator closes the valve when the return flow pressure is too
high. The Type 46-7 is mainly used in district heating supply networks and industrial plants.
The regulator and actuator are designed to operate under exactly defined conditions (e.g.
operating pressure, process medium, temperature). Therefore, operators must ensure that the
regulator and actuator 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 devices
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 regulator is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
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.
