Type 43-1 and Type 43-2 Temperature Regulators - 1

T 2171 EN Type 43-1 and Type 43-2 Temperature Regulators Series 43 Self-operated Temperature Regulators Application Regulators for district heating systems, heat generators, heat exchangers and other HVAC and industrial applications. Temperature set points from 0 to 150 °C · G ½ to G 1 · DN 15 to 50 · Pressure rating PN 25 · Suitable for liquids up to 150 °C and non-flammable gases up to 80 °C · The valves close when the temperature rises. Note Typetested temperature regulators (TR), safety temperature monitors (STM) and safety temperature limiters (STL) are available. Special features •• Low-maintenance proportional regulators requiring no auxiliary energy •• Temperature sensor suitable for installation in any desired position and for operation at high excess temperatures (50 K above the set point), designed for operating pressures up to 40 bar (u EB 2430) •• Globe valves with plug balanced by a piston •• Particularly suitable for district heating supply networks •• Suitable for gases and liquids •• Special version: fast-responding thermostats for instantaneous water heater (u EB 2430-3) Versions (Fig. 1 to Fig. 2) Fig. 2: Type 43-2 with flanged body made of spheroidal graphite iron, DN 40 (special version) With body of red brass CCC499K With body stainless steel 1.4408 The regulators consist of a valve and control thermostat with set point adjuster, a capillary tube and temperature sensor operating according to the adsorption principle. Valve body made of red brass, spheroidal graphite iron or stainless steel. See Data Sheet u T 2176 for versions with double adapter or manual adjuster for the attachment of additional control thermostats –– Type 43-1 · Temperature regulator with Type 2431 Valve G ½ to G 1 female thread · Type 2430 Control Thermostat Sensor optionally with or without thermowell –– Type 43-2 · Temperature regulator with Type 2432 Valve DN 15 to 50 · With welding ends (special version with threaded ends, flanges or with flanged body) · Type 2430 Control Thermostat · Sensor optionally with or without thermowell Typetested safety devices The register number is available on request. The following versions are available: Type 43-1 and Type 43-2 Temperature Regulators (TR) for which the maximum operating pressure must not exceed the maximum permissible differential pressure Δp specified in the Fig. 3: Type 43-1 Temperature Regulators technical data. Only SAMSON thermowells can be used for sensors with thermowells. Further details on the selection application of typetested equipment can be found in Information Sheet u T 2181.
