T 2172 EN Type 43-5 and Type 43-7 Self-operated Temperature Regulators (for heating) Type 43-6 Self-operated Temperature Regulator (for cooling) Application Temperature set points from 0 to 150 °C · Valves G ½ to G 1 · DN 15 to 50 · Pressure rating PN 25 · Suitable for liquids and steam up to 200 °C and non-flammable gases up to 80 °C · For plants to be heated or cooled. 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 bellows •• Compact design with particularly low overall height •• Suitable for liquids, gases or vapors. Versions (Fig. 1 to Fig. 4) The regulators consist of a globe 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.
