特徴とする弁装置。 A valve device that uses an electromagnetic actuator to open and close each on-off valve provided in each of two flow paths includes an electromagnetic coil connected to a current supply circuit, and a plunger disposed within the electromagnetic coil so as to be movable in the axial direction. a first magnetic pole member that magnetically attracts the plunger in a stable position in one direction; a second magnetic pole member that magnetically attracts the plunger in a stable position in the other direction; and the current supply circuit. The magnetic flux generated in the electromagnetic coil is selectively supplied with currents in different directions from the plunger,
A yoke for allowing flow to flow through the first magnetic pole member or the second magnetic pole member, and two on-off valves each having a valve body attached to each end of the plunger and opened by the plunger. Features a valve device.
