Abstract: An electromagnetic valve and an electromagnetic valve assembly are provided. The electromagnetic valve includes: a valve body, which at least includes a valve seat, the valve seat being mounted on a mounting base; a magnetic conductive frame, which is fixed to the valve seat; and an electromagnetic driving assembly, which is mounted in the magnetic conductive frame. The magnetic conductive frame is provided with a positioning member, and the positioning member cooperates with the mounting base so as to restrict the electromagnetic driving assembly from rotating relative to the mounting base.
