Attaching and removing plug connector
●DC5V, DC12V, DC24V
Use fingers to insert the connector into the
pin, push it in until the lever claw latches onto
the protruded section of the connector
housing, and complete the connection.
To remove the connector, squeeze the lever
along with the connector, lift the lever claw
up from the protruded section of the
connector housing, and pull it out.

Manual override
Non-locking type
To operate the manual override, press it all the
way down. The valve works the same as when in
the energized state as long as the manual
override is pushed down, and returns to the rest
position upon release.

Indication of
polarity(DC)
Cautions: 1. Do not apply megger between the
lead wires.
2. The DC solenoid will not short circuit
even if the wrong polarity is applied,
but the valve will not operate.
3. Leakage current inside the circuit
could result in failure of the solenoid
valve to return, or in other erratic
operation. Always use it within the
range of the allowable leakage
current. If circuit conditions, etc.
cause the leakage current to exceed
the maximum allowable leakage
current, consult us.
4. Hold voltage fluctuation to an
absolute minimum. In particular,
maintain the minimum operating
voltage at 90% or more of the rated
voltage during solenoid valve
operation.

Crimping of connecting lead wire and contact
To crimp lead wires into contacts, strip off
4mm [0.16in.] of the insulation from the end
of the lead wire, insert it into the contact, and
crimp it. Be sure at this time to avoid catching
the insulation on the exposed wire crimping
section.

Locking type
To lock the manual override, use a small
screwdriver to push down on the manual
override all the way and turn it 45 degrees or
more. Either turning direction at this time is
acceptable. When locked, turning the manual
override from the locking position releases a
spring on the manual override, returns it to its
original position, and releases the lock.
When the manual override is not turned, this
type acts just like the non-locking type.
Insulation(Maximum outer
diameterφ1.7)
Cautions: 1. Do not pull hard on the lead wire.
2. Always use a dedicated tool for
crimping of connecting lead wire and
contact.

Manufactured by Sumiko Tech, Inc.
Crimping tool: Model F1-702062
Manufactured by Sumiko Tech, Inc.
Attaching and removing contact and connector
Insert the contact with lead wire into a plug
connector □ hole until the contact hook latches
on and is secured to the plug connector. Confirm
that the lead wire cannot be easily pulled out.
To remove it, insert a tool with a fine tip (such as
a small screwdriver) into the rectangular hole on
the side of the plug connector to push up on the
hook, and then pull out the lead wire.
Cautions: 1. Do not pull hard on the lead wire. It
could result in defective contacts,
breaking wires, etc.
2. If the pin is bent, use a small
screwdriver, etc. to gently straighten
out the pin, and then complete the
connection to the plug connector.
TURN
PU
SH
※Illustration shows the 240 series.
Cautions: 1. Always release the lock of the locking
type manual override before
commencing normal operation.
2. Do not attempt to operate the manual
override with a pin or other object
having an extremely fine tip. It could
damage the manual override button.
3. Do not turn the adjusting knob more
than the amount needed. It could
result in defective operation.

How to read the graph
How to read the graph
When the supply pressure is 0.5MPa [73psi.]
and flow rate is 25R/min [0.88ft.3/min.] (ANR),
the valve outlet pressure becomes 0.4MPa
[58psi.].
When the supply pressure is 0.5MPa [73psi.]
and flow rate is 20R/min [0.71ft.3/min.] (ANR),
the valve outlet pressure becomes 0.4MPa
[58psi.].
