ヨナ。 An electro-pneumatic positioner for controlling the stem position of a valve driven by pneumatic pressure in response to an input current, comprising: a drive means for driving a first flapper in response to an input current; a first nozzle that is provided at one end of the first flapper and constitutes a nozzle flapper mechanism; an exhaust valve that performs exhaustion from a back pressure chamber into which back pressure of the first nozzle is input; and an exhaust valve that engages with one end of the exhaust valve. a pilot relay that amplifies the back pressure of the first nozzle and outputs it as output pressure; a spring that has one end fixed to the other end of the exhaust valve; and a spring that is attached to the other end of the spring. a second flapper;
a second nozzle facing the flapper and having its other end opened to the atmosphere and attached to the back pressure chamber and forming a nozzle flapper mechanism with the second flapper; a control valve to which the output air pressure of the control relay is input; An electropneumatic positioner comprising feedback means for feeding back a displacement signal of the control valve to an input side.
