Structure Drawing

Structure drawing when not energized

Structure drawing when not energized

In an non-energized state, the spool valve (3) is pushed upward with the reaction force of the spring (4), sealing (1) while (2) and (3) are opened.
Air flow direction: (1) ⇔ block, (2) ⇔ (3)

Structure drawing when energized

Structure drawing when energized

When the coil (6) is energized, the plunger (7) is attracted and through the overtravel assembly it pushes down the spool valve (3). As a result, (3) is sealed while (1) and (2) are opened.
Air flow direction: (1) ⇔ (2), (3) ⇔ block

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 drawings in the manufacturer's catalog. The drawing is for the N.C. specification.
  • *How to switch from N.C. specification to N.O. specification: The product is configured as N.C. specification at the time of shipment from the factory. Remove the 2 mounting screws of the required valve and rotate the valve main body 180° on the manifold base to change the valve from a N.C. specification to a N.O. specification. (Confirm that gaskets are mounted on the valve mounting surface at this time.) Tighten the screws sufficiently. Mounting screw tightening torque: 3 N⋅m

Other

*See the manufacturer's catalog for information other than that above.
