Structure Drawing
Structure drawing when not energized
The spool valve (2) is pushed upward with the reaction force of the spring (3), sealing port (P) while port (A) and port (R) are opened.
Structure drawing when energized
The armature assembly (5) is attracted to the fixed core (6), pushing down the spool valve (2) with the push rod (7). As a result, port (R) is sealed while port (P) and port (A) are opened. At this time, a gap is formed between the armature assembly (5) and the fixed core (6), but the magnetic attraction of the coil overcomes the spring force inside the armature assembly (5), causing the armature assembly (5) to be pulled into close contact with the fixed core (6).

Precautions
- *1The bottom of the solenoid valve has a breather hole for the main valve. Take proper measures to prevent this hole from being blocked as this will lead to a malfunction. *Ordinarily, when the solenoid valve is mounted on a metal surface, it can breathe through the breather hole via the breather groove. However, if the surface on which it will be mounted is made of rubber, the rubber could deform and block the hole.
- *2Take proper measures to prevent dust and foreign matter from entering through unused ports, such as the exhaust port. The grommet portion contains a breather hole for the armature. Take proper measures to prevent dust or foreign matter from accumulating in this area.
Manifold specification specific product precautions
- *When mounting the valve on the manifold base, the mounting orientation is set. Mounting in the wrong direction may cause connected equipment to malfunction. When mounting, see the manufacturer's catalog regarding how to switch from a N.C. specification → N.O. specification.
- *Each valve is fixed to the manifold base with two M4 mounting screws. Tighten the screws sufficiently when re-mounting.
Mounting screw tightening torque: 1.4 N⋅m - *When mounting, tighten the M4 or equivalent screws evenly into the mounting holes of the manifold base.
Other
*See the manufacturer's catalog for information other than that above.
