An electrically controlled valve is arranged to be mounted on a printed circuit without requiring any fasteners other than the terminals which provide electrical connections to the coil of a solenoid. The valve has three ports arranged to permit one of the ports to be selectively connected to either one of the other two ports. The plunger of the solenoid is disposed in a receiver that extends into the central longitudinal passage of the solenoid coil which establishes a magnetic field when the coil is electrically energized. A spring causes the plunger to seal off one port when the coil is unenergized. In that position of the plunger the other two ports are connected by channels in the plunger. Upon electrical energization of the coil, the plunger moves to a new position where it seals off a different one of the three ports while opening a connecting passage between the remaining two ports.
