Zusammenfassung:	PROBLEM TO BE SOLVED: To guarantee a remarkably improved sealability in a valve seat of a proportional valve for gaseous medium control.SOLUTION: A proportional valve includes: a nozzle body 2 having at least one flow opening; a closing member 4 which opens/closes the flow opening in a valve seat 21; and an elastic seal member for sealing the valve seat 21. The seal member includes a notch 50 provided with an inner wall area 51, and the inner wall area 51 is pressed with a pressure of a gaseous medium while closing the proportional valve.
