Abstract: An electromagnetic valve manifold includes valve assemblies arranged in a single direction, each valve assembly including electromagnetic valves arranged in the single direction, a slave station disposed at one of ends of the electromagnetic valve manifold in the single direction, and a valve driving unit disposed in correspondence with each of the valve assemblies. The slave station includes a slave station output port that sends a control signal and valve driving unit power to the valve driving units. The valve driving units each include an electromagnetic valve power input port that receives electromagnetic valve power from an external device and a circuit board configured to control driving of the electromagnetic valves of a corresponding one of the valve assemblies using the control signal and send the electromagnetic valve power to the electromagnetic valves.

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.
