Abstract
A valve device is capable of precisely adjusting a flow rate variation with time, aging, or the like without using an external sensor or using as few external sensors as possible. The apparatus includes an adjusting actuator for adjusting the position of the operating member positioned at the open position, a communication unit for receiving adjustment information relating to the adjustment of the opening degree of the flow path by the valve element from the outside of the apparatus, and a control unit for adjusting the position of the operating member by driving the adjusting actuator based on the adjustment information.
