Intended use
The SAMSON Type 43-3 Regulator is a temperature regulator with three-way valve for mix-
ing and diverting service. The regulator consists of a Type 2433 Valve and a Type 2430
Control Thermostat. The valve and control thermostat are delivered separately and must be
assembled according to the instructions in these mounting and operating instructions.
The self-operated regulator is used to control the temperature in the plant to the adjusted set
point. The Type 43-3 Regulator is used to control water.
The regulator is designed to operate under exactly defined conditions (e.g. operating pres-
sure, 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 controllers 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.
