Warning
1. Confirm the specifications.
Do not operate at pressures, temperatures, etc., beyond the
range of specifications, as this can cause damage or
malfunction. (Refer to the specifications.)
Please contact SMC when using a fluid other than compressed
air (including vacuum).
We do not guarantee against any damage if the product is
used outside of the specification range.
2. Products mentioned in this catalog are not designed
for use as stop valves with zero air leakage.
A certain amount of leakage is allowed in the products’
specifications.
Tightening the needle forcibly to achieve zero leakage may
result in damage of contact face stopper.
Fully closed
Stopper face Contact face stopper
3. Do not disassemble the product or make any
modifications, including additional machining.
Doing so may cause human injury and/or an accident.
4.The flow rate characteristics for each product are
representative values.
The flow rate characteristics are characteristics of each
individual product. Actual values may differ depending on the
piping, circuitry, pressure conditions, etc.
There will be no flow rate from the fully closed position until 1
to 1.5 turns due to the product characteristic, but this is not the
problem.
5. Sonic conductance (C) and critical pressure ratio (b)
values for products are representative values.
For controlled flow direction values the needle is fully open. For
free flow direction values the needle is fully closed.
6. Check if PTFE can be used in the application.
PTFE powder (Polytetrafluoroethylene resin) is included in the
seal material of the male thread type piping taper thread.
Confirm that the use of it will not cause any adverse effects on
the system.
Please contact SMC if the Material Safety Data Sheet (MSDS)
is required.
7. Speed controllers are designed to control the speed
of the actuator.
Mounting
Warning
1. Operation manual
Install the product and operate it only after reading the
operation manual carefully and understanding its contents.
Also, keep the manual where it can be referred to as
necessary.
2. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance
and inspection.
3. Tighten threads with the proper tightening torque.
When installing the products, follow the listed torque
specifications.
4. Screw the R screw into the Rc thread, the NPT screw
into the NPT thread and the G screw into the G
thread.
5. After pushing the knob down to lock, confirm that it
is locked.
Confirm that the knob is locked by pushing the knob in after
adjusting the cylinder speed. When the speed controller is
unlocked, the set flow may change.
If the knob is pulled with force while the speed controller is
unlocked, it may result in breakage. When it is unlocked, do not
pull the knob out with force.
Unlocked

Locked

6. Check the degree of rotation of the needle valve.
As the needle valve has a stopper mechanism for max. open,
it is not possible to rotate beyond the given limit. Forceful
rotation of the needle beyond this point will cause damage, so
check the table below for the number of rotations.
Connection thread size Number of needle rotations (reference)
M3, M5, 10-32UNF 8
1/8 10
7. Do not use tools, such as pliers, to rotate the knob.
This can cause the idle rotation of the knob or damage.
8. Confirm the air flow direction.
Mounting backward is dangerous because the speed adjust-
ment needle will not work, and the actuator may lurch suddenly.
JAS-S Series
Specific Product Precautions 1
Be sure to read this before handling the products. Refer to the back cover for safety instruc-
tions. For flow control equipment precautions, refer to the “Handling Precautions for SMC
Products” and the “Operation Manual” on the SMC website: https://www.smcworld.com

Mounting
Warning
9. Adjust the needle by opening the needle slowly after
having closed it completely.
Loose needle valves may cause unexpected sudden actuator extension.
When a needle valve is turned clockwise, it is closed and cylinder speed
decreases. When a needle valve is turned counterclockwise, it is open
and cylinder speed increases.
10. Do not turn the knob forcibly to prevent the scale
from going outside the scale display range.
The scale may indicate a wrong value, possibly leading to a wrong setting.
Wrong use example: While the scale indication range is 0 to 8, forcefully
turning the knob in the opening direction from
graduation 8 caused the scale to indicate 0.
Connection thread size Scale indication range
M5 0 to 8 graduations
1/8 0 to 10 graduations
The scale indication range is also printed on the product.
11. Slowly turn the knob in the opening direction or
closing direction.
If quick reciprocal operations between two graduations like 0 R
1 R0, which is not conducted in usual flow rate setting, are
conducted, a scale malfunctioning may occur. (Guide for
rotation speed: 1 [rev/sec] or below)
12. Do not apply excessive force or shock to the body
or fittings with an impact tool.
This can cause damage or air leakage.
13. Refer to the Fittings and Tubing Precautions for
handling One-touch fittings.
14. Insert the hexagon wrench into the end of the
hexagonal hole of the stud when removing and
mounting the speed controller.
Do not apply torque at other points, as the product may be
damaged. Rotate body A manually for positioning after installation.
Refer to the applicable dimension of the hexagon wrench.

Piping Threads with Sealant
Caution
1. If the fitting is tightened with excessive torque, a
large amount of sealant will seep out. Remove the
excess sealant.
2. Insufficient tightening may loosen the threads or
cause air leakage.
3. For reuse
1) Normally, fittings with a sealant can be reused up to 2 to 3
times.
2) To prevent air leakage through the sealant, remove any
loose sealant stuck to the fitting by blowing air over the
threaded portion.
3) If the sealant no longer provides effective sealing, wind
sealant tape over the sealant before reusing. Do not use
any form other than the tape type of sealant.
4. Once the fitting has been tightened, backing it out
to its original position often causes the sealant to
become defective. Air leakage will occur.
Piping
Caution
1. Refer to the Fittings and Tubing Precautions for
handling One-touch fittings.
2. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil, and
other debris from inside the pipe.
Piping Threads with Sealant
1. Winding of sealant tape
When screwing piping or fittings into ports, ensure that chips
from the pipe threads or sealing material do not enter the
piping. Also, if sealant tape is used, leave 1 thread ridge
exposed at the end of the threads.
