Abstract: An electromagnetic valve manifold includes an electromagnetic valve including a discharge port, a manifold base including a discharge passage that is connected to the discharge port, and a check valve. The check valve includes a valve member, a valve housing including a valve seat, and an urging member. The valve housing includes a valve chamber that accommodates the valve member, a peripheral wall that defines the valve chamber, a valve hole that connects the valve chamber to the discharge port, and a discharge opening that connects the valve chamber to the discharge passage. The check valve is disposed in the discharge passage. The discharge opening is formed in the peripheral wall, at least a part of the discharge opening overlapping with the valve seat in a direction orthogonal to a moving direction 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.
