The tap is actuated by an energy source and comprises sensors (13,31) to detect that the actuator operates the tap. A first sensor measures a magnitude representing the power consumed from the energy source. An electronic circuit (11,29) is connected to the first sensor and to a comparator (10,28) which, when the actuator operates the tap, compares the magnitude representing the power consumed from the energy source with a set value, and emits an instruction as a function of this comparison. In the case of a pneumatic energy source a pressurised fluid is used. The actuator has a pneumatic valve piston (5) and the first sensor (13) measures the fluid pressure on either side of the piston (5). In the case where an electrical current energy source is used. the actuator is an electro-mechanical transducer (23) and the first sensor (31) measures the electrical power consumed from the energy source at the time the tap is operated.
