Operating principle

When the torque motor (1E) receives input power, its armature (2Eb) pivots in the direction of arrow A around the fulcrum plate spring (3). This pivot separates the flapper (5) from the nozzle (4), reducing the pressure in the nozzle’s back-pressure chamber (12) and upsetting its balance with the pressure chamber (11). Consequently, the relay spool (13) actuates, opening port A (15a), which connects the lower cylinder pressure chamber (17e) to the exhaust port (9) and causes the stem (18) to descend. This action is transmitted through the feedback lever (19), cam lever (20), range arm (23), and zero arm (26), extending the feedback spring (7) and continuing until the spring’s tensile strength equals the torque motor’s (1E) absorption power. Thus, the stem (18) moves in proportion to the input signal.
