Abstract
An electromagnetic valve which can control a fluid flow in dual mode, i.e. a small amount of fluid at a first step and a large amount of fluid at a second step, which adopts a bypass means of magnetic flux for obtaining the first step and a resistance means that does not allow the magnetic flux to flow in the first step while it allows it to flow in the second step for obtaining the second step.
