  • Publication number: 20200370671
    Abstract: A control device for a valve device can detect open/close state of the valve device without using limit switches. The valve device includes a diaphragm for opening and closing a flow path for flowing a fluid, a coil spring for biasing the diaphragm in the closing direction of flow path, a main actuator for driving it against the biasing force of the coil spring, and an adjusting actuator using a piezoelectric element for adjusting the opening degree of the flow path determined by the diaphragm. The controller detects the open/close state of flow path based on the voltage generated by the piezoelectric element of the adjusting actuator, and controls valve device using the detection signal.
