Self-operated Temperature Regulators Type 1u Temperature Regulator - 2

Principle of operation (see Fig. 2) The regulators operate according to the liquid expansion principle. Temperature sensor (13), capillary tube (10) and operating element (7) are filled with an expansion liquid. The liquid changes its volume depending on the temperature, causing the operating element (7) and thus the valve's plug stem (5) with the plug (3) to move. The position of the plug determines the flow rate of the heat transfer medium across the area released between the plug and seat (2). The temperature set point can be adjusted using a key (11) to a value that can be read off the...
