ABSTRACT:
A fluid control valve comprises a valve element, a casing, a fluid flow passage formed in the casing, and an actuator drivingly moving the valve element to the casing in the axial direction. The fluid flow passage introduces a fluid from the inlet for the fluid and supplies the fluid into the clearance between the inner wall surface of a guide part and the outer peripheral surface of the valve element to lift the valve element relative to the inner wall surface of the guide part in the state of non-contact with each other. The actuator moves the valve element in the axial direction in the state of non-contact and changes the clearance between the outlet of the casing and the tip of the valve element to control the output flow amount or output pressure of the fluid.
