In particular, if air bubbles or cavities in the casting material appear on the surface during cutting, and the valve seat leaks even in one place,
The valve body was defective and could not be used.

b is formed to protrude in the axial direction from one flange 11a. A fluid inlet or passage hole 13 is formed in the protruding portion around the flange side and penetrates inside and out, and an outlet or valve port 14 is formed at the end (lower end in the figure). A valve seat 12 is formed integrally with a protruding portion 11b at an inner peripheral portion of the valve port 14. A fixed iron core 15 is fitted and fixed at the other end (upper side in the figure) of the central space of the coil bobbin, and a movable iron core is movably provided at the protrusion side. A valve body 17 is integrally formed and protruded from the lower end of the movable iron core 16, and this valve body 17 engages in and out of the valve seat 12 of the bobbin to open and close the fluid passage.

Furthermore, even if defects such as air bubbles appear during casting during processing, there is no need to discard the product as a defective product since this does not pose any hindrance to the formation of fluid passages. Further, since each solenoid valve is an independent unit and is detachable, it is easy to partially replace the valve even if it is damaged, which is extremely economical. Furthermore, since the valve seat is formed integrally with the coil bobbin, assembly is simple and inexpensive.
