Abstract
Valve with an actuator which consumes power from an energy source and which comprises a device capable of detecting that the actuator is operating the valve, a first sensor for measuring a value representative of the power consumption from the energy source and an electronic circuit connected to the first sensor and to the device so as to compare the value representing the power consumption from the energy source with a reference value, during operation of the valve by the actuator, and provide information on the basis of this comparison.
