1 Safety instructions and measures
Intended use
The Type 42-36 E Pressure-independent Control Valve (PICV) with an electric actuator is in-
tended for flow control of liquids up to 150 °C and gases up to 80 °C. It consists of a
Type 2423 Valve, a Type 2426 Actuator and an electric actuator. The regulator is delivered
as separate components.
The pressure-independent control valve is mainly used to control liquids or gases in district
heating supply networks.
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 applications or condi-
tions other than those 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
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.
