制御弁。[Claims for Utility Model Registration] A digital fluid control valve that uses a pulse motor as a driving source, converts the rotation of the pulse motor into linear motion by a cam mechanism, and controls the flow rate or directional flow rate of fluid in N stages by moving a spool. In this method, a pulse motor having a step rotation angle per pulse that is 1/N or less of an effective rotation amount that provides a linear movement amount approximately proportional to the motor rotation amount is used as a drive source, and the rotation of the pulse motor is directly A digital fluid control valve characterized by transmitting information to a cam mechanism.
