摘要：The invention concerns a method which consists in displacing the valve (1) stemand closure between a position for opening and a position for closing the valve (1), bymeans of a pneumatic actuator (4) of the valve (1) supplied with pressurized gas;measuring, for at least one valve stem displacement cycle, the pneumatic actuator (4)supply pressure, the valve stem displacement; recording the stress exerted on the valvestem and diagnosing the valve operating conditions based on the measured values.Sensors (27) can also be used to observe the actuating of contactors at the end of thevalve (1) travel and to sense an electrovalve (23) control signal for controlling thepneumatic actuator (4) supply. The valve can be actuated by its normal operatingconditions control or by a pneumatic assembly independently of the valve normaloperating conditions. The invention is particularly applicable to valves disconnecting anuclear reactor circuit.
