Abstract: An electromagnetic valve includes a valve casing, which has a valve hole, a spool valve in the valve hole, first and second output ports each communicating with the valve hole, first and second pressure introduction holes, which respectively communicate with the first and second output ports, first and second pressure sensors, which is respectively fitted in the first and second pressure introduction holes, sealing members, which are arranged between the respective pressure sensors and the pressure introduction holes, first and second substrates, on which the corresponding first and second pressure sensors are mounted, and a housing, which accommodates the first and second substrates, has the first and second pressure introduction holes, and is attached to the valve casing. The first and second substrates are arranged to be opposed to each other in a state of being upright in a direction perpendicular to the movement direction of the spool valve.

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 a manifold base including passages, a pilot electromagnetic valve including a valve body mounted on a mounting surface of the manifold base, a gasket arranged between the mounting surface and the valve body, and a check valve. The valve body includes an electromagnetic valve-side pilot fluid discharge passage. The manifold base includes a base-side pilot fluid discharge passage that opens in the mounting surface and communicates with the electromagnetic valve-side pilot fluid discharge passage. The check valve is configured to prevent fluid from flowing from the base-side pilot fluid discharge passage to the electromagnetic valve-side pilot fluid discharge passage. The check valve is integrated with the gasket.
