While pressing, turn in the direction of the arrow.
If it is not turned, it can be operated the same way as the non-
locking type.
When operating the locking type D with a screw driver, turn it
gently using a watchmakers screw driver.

While pressing, turn it the direction of the arrow.
If it is not turned, it can be operated the same way as the non-
locking type.
When locking the manual override on the push-turn locking
types (D, E), be sure to push it down before turning.
Turning without first pushing it down can cause damage to the

Series SY3000/5000/7000/9000 can be used as normally closed
(N.C.) or normally open (N.O.) 3-port port valves by closing one
of the cylinder ports (A or B) with a plug. However, they should be
used with the exhaust ports kept open. (Refer to pages 318 to
323 for dedicated 3-port solenoid valve.)
Solenoid valves with grommet and L/M type plug connector AC
specifications have a built-in rectifier circuit in the pilot section to
operate the DC coil.
With 200 V, 220 VAC specification pilot valves, this built-in rectifier
generates heat when energized. The surface may become hot
depending on the energized condition; therefore, do not touch the
solenoid valves.
With series SY, the pilot valve and main valve share a common
exhaust inside the valve. Therefore, do not block the exhaust port
when arranging the piping.
