Abstract: An electromagnetic valve manifold includes an electromagnetic valve and a manifold base. The electromagnetic valve includes a manual shaft. The manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows movement of the valve member relative to the valve hole, and a second switching position in which the manual shaft restricts movement of the valve member relative to the valve hole. The manual shaft includes a projection that is projected into and retracted from the valve hole. The valve member includes at least one recess in an outer surface of the valve member. The manual shaft is configured such that, in a state in which the manual shaft is located in the second switching position, the projection is projected into the valve hole and engaged with the recess, so as to restrict movement of the valve member.

Abstract: Passage forming blocks of a first pilot valve and a second pilot valve each include a supply passage, which opens in a first surface and a second surface and is connected to a valve chamber, a first output passage, which opens in the first surface and are connected to the valve chamber, and a second output passage, which opens in the first surface. Further, the passage forming blocks each include an output passage connecting recess. The output passage connecting recess is provided in a section of the second surface that overlaps with an opening region of the first output passage, which opens in the first surface, and is connected to the second output passage. The first output passage of the first pilot valve is connected to the second output passage of the second pilot valve via the output passage connecting recess of the second pilot valve.
