Abstract

PURPOSE: To obtain stable operation of a driving gear throughout a wide range, by mounting a connection joint, combining a non-linear characteristic movable iron and flapper, to a position variable mechanism.
CONSTITUTION: In a pilot valve, constituted by a nozzle 5 and flapper 4, and electropneumatic positioner, constituted by a moving-iron force motor 1 operated by receiving an electric signal, a connection joint 3, combining a moving-iron 2, having such a characteristics that a moving amount of the moving-iron is nonlinear for an input current value to the force motor 1, and the flapper 4, is mounted to a position variable mechanism 3'. In this way, a gain of the electropneumatic positioner can be continuously varied, thus stable operation can be performed throughout a wide range of a driving gear.
