A valve body 2 is connected to a plunger 10 that responds to the primary pressure acting on a diaphragm 20, and this valve body 2 is made to face a valve seat 12 formed in the valve body 1 from the downstream side, so that the plunger 10 and the valve body 2 In this gas proportional valve, a biasing force for canceling the dead weight of the plunger 10 and the valve body 2 is applied to the axis of the plunger 10 and the valve body 2. A gas proportional valve uses magnetic force as a means of biasing permanent magnets located symmetrically to each other.
