ABSTRACT:
There are provided a flow control valve and a flow control device suitable for allowing flow control of a fluid with high accuracy. Diaphragms8and9are mounted to upper and lower openings, respectively, of an air chamber6. The upper diaphragm8and the lower diaphragm9are connected by a connecting shaft10and have pressurized surfaces with different areas that receive pressure of the air chamber6. This causes a difference between forces applied to the two diaphragms8and9, and the difference causes the connecting shaft10and a valve body2mounted to an outer surface of the lower diaphragm9to slide and be separated from a valve seat23.
