装置。Defined by the valve body and the valve body, the valve body is separated from and seated on a valve seat formed in the valve body to communicate and block the flow path, and the valve body and the valve body restrict the flow path on the upstream side. an opening provided in the valve body that communicates the chamber with the downstream flow path; It is composed of a plurality of drive means each having a pilot valve body that engages with the pilot valve body, and an engagement member that is individually engaged with the pilot valve body, each of which can be freely driven and displaced. A valve device configured to displace the pilot valve body in a multistage manner by sequentially displacing members to different positions.
