T 2133 EN Type 9 Temperature Regulator Self-operated Temperature Regulators · With balanced three-way valve 1) · Flanged connections Application Temperature regulators with mixing or diverting valve designed for plants that are heated or cooled using liquids · Control thermostats for set points from –10 to +250 °C · Three-way valves DN 15 to 150 · Nominal pressure PN 16 to 40 · Suitable for temperatures up to 350 °C Note Temperature regulators (TR), safety temperature monitors (STM), and safety temperature limiters (STL) tested according to DIN EN 14597 are available. The regulators consist of a three-way valve and a control thermostat with temperature sensor, set point adjuster with excess temperature protection, capillary tube, and operating element. Special features •• Low-maintenance proportional regulators requiring no auxiliary energy •• Wide set point range and convenient set point adjustment •• Three-way valve with plug balanced 1) by a stainless steel bellows, optionally available with a plug arrangement to mix or divert liquids •• Flow rate across the port AB almost independent of the valve plug position •• Valve body optionally available in cast iron, cast steel, or cast stainless steel •• Versions with double adapter and manual adjuster for temperature limiters or attachment of a second control thermostat.

Principle of operation (see Fig. 3 and Fig. 4) The regulators operate according to the liquid expansion principle. The temperature sensor (11), capillary tube (8), and operating element (7) are filled with an expansion liquid. The temperature-dependent change in volume of this liquid causes the operating element to move and, as a result, also moves the plug stem (5) with the attached plug (3). The position of the plug determines the flow rate of the heat transfer medium across the area released between the seat (2) and plug (3). The temperature set point is adjustable with a key (9) to a...
