    Abstract: A pilot type solenoid valve includes a pilot valve unit and a passage block unit. The passage block unit has a rectangular parallelepiped shape including a pair of wide opposite surfaces, and four side surfaces surrounding the wide opposite surfaces. The four side surfaces include a first surface on which the pilot valve unit is attached, and a second surface formed with at least either an input port or an output port. A valve element is a diaphragm valve and arranged in parallel to the pair of wide opposite surfaces. The passage block unit includes a block body forming a valve chamber around a valve seat, and a flat cover. The flat cover includes a recess forming the back chamber of the diaphragm valve, and the flat cover has a flat cover communication path formed to provide communication between the recess and a common path of the pilot valve unit.
