Abstract

PURPOSE: To ensure the accurate control for the control circuit in order to secure the desired open/close valve position by sending the signal to inhibit the operation of the close valve direction to the operation device via the signal given from the close valve position test device.
CONSTITUTION: Valve unit 1 gives the control to the open degree of the current path linked from the control system or the control system itself, and control circuit 5 transmits the operation signal to operation device for the control of the open degree of unit 1. Device 7 and circuit 5 possess the step motor and the small-size computer each, and circuit 5 transmits the signal to device 7 to give inhibition to the operation of the close valve direction via the signal sent from close valve position detector device 9. In this way, the accurate control is ensured to secure the desired open/close valve position.
