信号回路。 A valve opening/closing device configured to transmit a valve closing command signal from a shutoff valve controller to a solenoid of an electromagnetic shutoff valve, and to transmit a valve closing state signal from a sensor that detects that the shutoff valve is closed to the shutoff valve controller. In the signal circuit, a diode is inserted in series with the solenoid, and the sensor is connected in parallel with this diode, and a valve closing command signal is transmitted in the forward direction of the diode, and a valve closing state signal is transmitted in the same reverse direction. A valve opening/closing signal circuit characterized in that:
