Abstract: A fluid control valve for controlling high-temperature fluid includes: a valve body including a valve chamber communicating with first and second flow passages, and a valve seat provided in the valve chamber; a metal diaphragm that contacts with and separates from the valve seat; a stem that moves the metal diaphragm up and down; and an actuator that drives the stem. The first flow passage includes a first orifice having a diameter set to 50% or less of a diameter of the second flow passage. Alternatively, the second flow passage includes a second orifice having a diameter set to 50% or less of the diameter of the second flow passage. The diameter of the second flow passage is calculated by converting a cylindrical flow passage area defined between the valve seat and the metal diaphragm when separated from the valve seat into a diameter of a circular flow passage.

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.
