A direct operation temperature regulator, composed of a liquid temperature sensor and a control valve, where the regulator, depending on the type of a control valve used in connection with the temperature sensor, is implemented as a two-way mixing or separating direct operation temperature regulator and, when temperature increases, closes or opens the flow of the heating medium, characterized in that it has a corrugated sealing bellows (11), located between the spindle (12) of the valve (5) and a servo-motor (3) and is connected to the valve lifter (8), whereas the lifter (8) is at one end connected to the spindle (12), which has a pass-through hole along its entire length, and at the other end connected to a guide rail (9), a pointer (10) and a handwheel (10a), where the guide rail (9), the pointer (10) the handwheel (10a) together constitute a manual setting unit facilitating adjustment of the valve (5) head (5a), and is equipped with a piston (17), permanently connected to the bellows (16) of a fuse and mounted in the body (1a) with sealing in this body by means of sealing rings (18), and is also rotationally connected to the handwheel (19) and adjusted by means of that handwheel.<IMAGE>
