In the automatic control valve, leakage of the fluid from the grand packing portion has been a problem as main cause of failure. In this research, failure diagnosis of an automatic control valve is the last purpose. As the initial stage, the pressure measuring method of grand packing through grease using the semiconductor pressure transducer is proposed. First, the usefulness of this measuring method was evaluated in consideration of the influence of the grease. Next, this measuring method was used for the system and the distribution of the radius direction pressure of the many piled packing was measured. Consequently, it was indicated that it was possible to measure pressure change of packing when stem is operating. It will be possible to predict the disclosure of fluid from the axial pressure, if the relation between the radial pressure and the disclosure become clear from now on.
