Continuous duty type: VT307E
Energy-saving type: VT307Y (VT307W)
Vacuum spec. type: VT307V (VT307W)
Exclusive use of VT307E is recommended
for continuous duty with long time loading.
If low power consumption is required
for electronic control, “VY307Y(W)” (2
W DC) is recommended.
Specifications different from standard
are as follows.
This vacuum model has less air
leakage than the standard model under
low pressure. It is recommended for
vacuum application.
Caution
1. This model is for continuous duty, not
for high cycle rates. But even in low cycle
rates, if energizing the valve more than
once a day, please consult with SMC.
2. Energizing solenoid should be done at
least once in 30 days.
Specifications different from standard are as follows.

Note 1) Refer to Note 1) of standard
specifications.
Note 2) For the flow characteristics, refer
to “Flow Characteristics”.
Caution
1. Since this valve has slight air leakage, it
can not be used for vacuum holding
(including positive pressure holding) in
the pressure container.
Specifications different from standard
are as follows.

<Energized>
<De-energized>
When an electric current is applied to the molded
coil r, the armature t is attracted to the core
y, and through the push rod u, it pushes down
the spool valve w and port R is closed. Then,
port P and port A are connected. At this time,
there will be gaps between the armature t and
the core y, but the armature t will be
magnetically attracted to the core y.

Construction
Continuous duty type: VT317E
De-energized
Exclusive
use
of VT317E
is
recommended for continuous duty
with long time loading.
Energized
Caution
1. This model is for continuous duty, not for
high cycle rates. But even in low cycle
rates, if energizing the valve more than
once a day, please consult with SMC.
2. Energizing solenoid should be done at
least once in 30 days.
Vacuum spec. type: VT317V
This vacuum model has less air leakage
than the standard model under low
pressure. It is recommended for vacuum
application.
Caution
1. Since this valve has slight air leakage,
it can not be used for vacuum holding
(including positive pressure holding) in
the pressure container.
Specifications different from standard
are as follows.
Operating pressure range –101.2 kPa to 0.1 MPa
Operation principles
<De-energized>
Spool valve w is pushed upward by the return
spring e, port P is closed, and port A and port
R are opened.
<Energized>
When an electric current is applied to the molded
coil r, the armature t is attracted to the core
y, and through the push rod u, it pushes down
the spool valve w. Then, port P and port A are
connected. At this time, there will be gaps
between the armature t and the core y, but the
armature will be magnetically attracted to the
core y.

Specific Product Precautions
Be sure to read before handling. Refer to Front matters 58 and 59 for Safety Instructions
and pages 3 to 7 for 3/4/5 Port Solenoid Valve Precautions.
Caution
Caution
1. A bleed port for the main valve is located
at the bottom of the solenoid valve.
Since blocking it causes malfunction, do
not block it.
∗ Ordinarily, when the solenoid valve is
mounted on a metal surface, it can
breathe through the breather hole, via
the breather groove. However, in
particular, if the surface to be mounted
is made of the rubber, the rubber could
deform and block the hole.
2. Make sure that dust and/or other foreign
materials should not enter the valve
from the unused port (e.g. exhaust port).
Also, since there is a bleed port for the
armature in the manual override, do not
allow accumulation of dust and/or other
foreign materials to block bleed port.
Change of Electrical Entry Angle
1. Series VT317 can change electrical entry
angle. (4 positions)
2. How to change: Loosen the nut (1),
remove the coil (2) from the body
assembly (3), place the positioning pin (4)
at the required place, put back the coil (2)
to its place, and tighten sufficiently with
lock nut (1).

How to Use DIN Terminal
1. Disassembly
1) After loosening the thread (1), then if
the cover (4) is pulled in the direction of
the thread, the connector will be
removed from the body of equipment
(solenoid, etc.).
2) Pull out the screw (1), then remove the
gasket (2a) or (2b).
3) On the bottom part of the terminal block
(3), there’s a cut-off part (indication of
an arrow) (3a). If a small flat head
screwdriver is inserted between the
opening in the bottom, terminal block
(3) will be removed from the cover (4).
(Refer to graph at right.)
4) Remove the cable gland (5) and plain
washer (6) and rubber seal (7).
2. Wiring
1) Pass them through the cable (8) in the
order of cable ground (5), washer (6),
rubber seal (7), and then insert into the
housing (4).
2) Dimensions of the cable (8) are as
shown in the right figure. Skin the cable
and crimp the crimped terminal (9) to
the edges.
3) Remove the screw with washer (3e)
from the bracket (3e). (Loosen in the
case of Y-shape type terminal.) As
shown in the right figure, mount a
crimped terminal (9), and then again
tighten the screw (3e).
Note) Tighten within the tightening
torque of 0.5 N·m ±15%.
Note: a It is possible to wire even in the
state of bare wire. In that case,
loosen the screw with washer
(3e) and place a lead wire into
the bracket (3d), and then
tighten it once again.
b The maximum size for the
round terminal (9) is 1.25
mm2—3.5 and for the Y
terminal is 1.25 mm2—4.
c Cable (8) external: ø6 to ø12
Note) For the one with the external
external dimension ranged
between ø9 to ø12 remove the
inside parts of the rubber seal
(7) before using.
3. Assembly
1) Terminal box (3) connected with
housing (4) should be reinstated.
(Push it down until you hear the click
sound.)
2) Putting rubber seal (7), plain washer
(6), in this order into the cable
introducing slit on the housing (4), then
further tighten the cable gland (5)
securely.
3) By inserting gasket (2a) or (2b)
between the bottom part of the terminal
box (3) and a plug on an equipment,
screw in (1) on top of the housing (4)
and tighten it.
Note) Tighten within the tightening torque
of 0.5 N·m ±20%.
Note: The orientation of a connector can
be changed arbitrarily, depending
on the combination of a housing (4)
and a terminal box (3).

Precautions
Warning
When mounting valves on the manifold
base, the mounting orientation is decided.
If it is mounted in the wrong direction,
connected equipment may malfunction.
Mount it by referring to external
dimensions on page 1621. Besides, the
external dimensions are showing the case
of N.C. specifications.
Caution
Changing from N.C. to N.O.
The valves are assembled as N.C. valves
at the time of shipment.
By removing the two retaining screws
from the desired valves, and rotating each
valve body 180° and reassembling it on
the manifold base, it is possible to
reassemble an N.C. valve as an N.O.
valve. (When doing so, make sure that a
gasket is attached to the mounting
surface of the valve.) Properly tighten the
screws.
The tightening torque of the retaining
screws is 3 N·m.

Specific Product Precautions
Be sure to read before handling. Refer to front matters 58 and 59 for Safety Instructions
and pages 3 to 7 for 3/4/5 Port Solenoid Valve Precautions.
Caution
How to Wire DIN Terminal
1. The 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, in
particular, if the surface to be mounted
is made of the rubber, the rubber could
deform and block the hole.
Grommet
Bleed
groove
Bleed port
on main valve
Bottom of the solenoid valve
2. Make sure that dust and/or other
foreign materials do not enter the valve
from the unused port (e.g. exhaust
port).
The grommet portion contains a
breather hole for the core. Take proper
measures to prevent dust or foreign
matter from accumulating in this area.
Electrical Connection
For wiring to DIN terminal, connect the
positive (+) polar side with connector
terminal no. 1 and the negative (–) side
with connector terminal no. 2 when the
rated voltage is DC type.
How to Calculate the Flow Rate
For obtaining the flow rate, refer to front
matters 44 to 47.
1. Disassembly
1) After loosening the thread (1), then if
the cover (4) is pulled in the direction
of the thread, the connector will be
removed from the body of equipment
(solenoid, etc.).
2) Pull the screw (1), and then remove
gasket (2a) or (2b).
3) On the bottom part of the terminal
block (3), there’s a cut-off part
(indication of an arrow) (3a). If a
small flat head screwdriver is
inserted between the opening in the
bottom, terminal block (3) will be
removed from the cover (4).
(Refer to the figure below.)
4) Remove the cable gland (5) and
plain washer (6) and rubber seal (7).
2. Wiring
1) Pass them through the cable (8) in
the order of cable ground (5), washer
(6), rubber seal (7), and then insert
into the housing (4).
2) Dimensions of the cable (8) are the
figure as below. Skin the cable and
crimp the crimped terminal (9) to the
edges.
3) Remove the screw with washer (3e)
from the bracket (3e). (Loosen in the
case of Y shape type terminal.) As
shown in the below figure, mount a
crimped terminal (9), and then again
tighten the screw (3e).
Note) Tighten within the tightening
torque of 0.5 N·m ±15%.
Note: a It is possible to wire even in
the state of bare wire. In that
case, loosen the screw with
washer (3e) and place a lead
wire into the bracket (3d),
and then tighten it once
again.
b The maximum size for the
round terminal (9) is 1.25
mm2—3.5 and for the Y
terminal is 1.25 mm2—4.
c Cable (8) external: ø6 to ø12
Note) For the one with the external
dimension ranged between ø9
to ø12 remove the inside parts
of the rubber seal (7) before
using.
3. Assembly
1) Terminal box (3) connected with
housing (4) should be reinstated.
(Push it down until you hear the click
sound.)
2) Putting rubber seal (7), plain washer
(6), in this order into the cable
introducing slit on the housing (4),
then further tighten the cable gland
(5) securely.
3) By inserting gasket (2a) or (2b)
between the bottom part of the
terminal box (3) and a plug on an
equipment, screw in (1) on top of the
housing (4) and tighten it.
Note) Tighten within the tightening
torque of 0.5 N·m ±20%.
Note: The orientation of a connector
can be changed arbitrarily,
depending on the combination
of a housing (4) and a terminal
box (3).
