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.

Abstract: A pilot-operated solenoid valve includes a pilot valve unit having a fixed core and a movable core, and a passage block formed with a valve seat which a diaphragm valve element comes into contact or separates from. The pilot valve unit includes an NO port, a common port, and an NC port. The passage block is formed with an inlet port, an outlet port, a back chamber, an NO passage, a common passage, an NC passage an external exhaust passage, and an internal exhaust passage. The solenoid valve further includes a first or second metal ball to seal the external exhaust passage or the internal exhaust passage. The passage block includes a flat cover formed with a communication passage for communicating the recess with the common port.
