2. Specific Product Precautions

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.

We do not guarantee against any damage if the

product is used outside of the specifications

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.

(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 turns due to the product

characteristic, but this is not the problem.

(5)Sonic conductance and critical pressure

ratio values for products are representative

values.

For controlled flow direction values the needle is

fully open. For free flow direction values the

needle fully closed.

Warning

(6)Check if PTFE can be used in 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 effect on the system.

Please contact SMC if the Safety Data Sheet

(SDS) is required.

(7)Speed controllers are designed to control the

speed of the actuator.

Warning

(1)Operation Manual

Install the products 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.

(3)Tighten threads with the proper tightening

torque.

When installing the products, follow the listed

proper torque.

(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.

When the orange mark is visible, the speed

controller is unlocked. Confirm that the knob is

locked by pushing the knob in after adjusting

Warning

(6)Check the degree of rotation of the needle

valve.

The Products in this catalog are retainer type so

that the needle is not removed completely.

Over rotation will cause damage.

(7)Do not use tools such as pliers to rotate the

knob.

It can cause idle rotation of the knob or damage.

(8)Verify the air flow direction.

Mounting backward is dangerous, because the

speed adjustment needle will not work and the

actuator may lurch suddenly.

(9)Adjust the speed by opening the needle

slowly from the fully closed state.

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.

Unlock the knob before adjusting the needle

valve with a flat blade screwdriver. Excessive

torque may break the needle valve.

Refer to the operation applicable torque below.

(10)Do not apply excessive force or shock to

the body or fittings with an impact tool.

Caution

For M5,10-32UNF

First, tighten it by hand, then give it an additional

1/6 turn to 1/4 turn with a hexagon wrench.

Refer to Table below for reference.

Note) Excessive tightening may damage the

thread portion or deform the gasket and

cause air leakage.

If the screw is too shallowly screwed in, it

may come loose or air may leak.

②Chamfered area for female thread

In compliance with ISO 16030 (air pressure fluid

dynamics－connection－ports and stud ends),

the chamfered dimensions shown in the table

below are recommended.

(2)For R, NPT, G thread

①Tightening method

When tightening the stud, insert an appropriate

hexagon wrench to the hexagonal hole after

tightening it by hand.

Refer to Table below for reference.

②Chamfered area of female thread

By chamfering as shown in the table below,

machining of threads is easier and effective for

burr prevention.

*G thread (face seal) complies with

ISO16030-2001.

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)Reuse

①Normally, fittings with a sealant can be reused

2 to 3 times.

②To prevent air leakage through the sealant,

remove any loose sealant stuck to the fitting

by blowing air over the threaded portion.

③If the sealant no longer provides effective

sealing, wrap sealing tape over the sealant

before reusing. Do not use the sealant in any

form other than a tape type.

(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

(5)Use R external threads with Rc internal

threads and NPT external threads with NPT

internal threads.

Caution

(1)Refer to the Fittings & Tubing Precautions

for handing 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.

(3)Winding of sealant tape

When screwing together pipes and fittings, etc.,

be certain that chips from the pipe threads and

sealing material do not get inside the pipe.

Also, when the sealant tape is used, leave

approx. 1 thread ridges exposed at the end of the

threads.

Caution

(1)Connection and disconnection of tube from

one-touch fitting

①Installation of tube

1)Cut the tube perpendicularly, being careful not

to damage the external surface. Use an SMC

tube cutter TK-1, 2, 3. Do not cut the tubing with

pliers, nippers, scissors, etc., otherwise the

tubing will be deformed and problems may

result.

2)The outside diameter of the polyurethane tubing

swells when internal pressure is applied to it.

Therefore, it may be impossible to re-insert the

tubing into One-touch fittings. Check the tubing

outside diameter, and when the accuracy of the

outside diameter is +0.07mm or larger for φ2,

and +0.15mm or larger for other sizes, re-insert

it into the One-touch fitting without cutting the

tube.When the tubing is re-inserted into the

One-touch fitting, confirm that the tubing goes

through the release button smoothly.

3)Grasp the tubing, and slowly push it straight

into the One-touch fitting until it comes to a

stop.

4)Pull the tubing back gently to make sure it has a

positive seal. Insufficient installation may cause

air to leak or the tubing to release.

②Removal of the tube

1)Push the release button flange evenly and

sufficiently to release the tube.Do not push in the

tubing before pressing the release button.

2)Pull out the tubing while keeping the release

button depressed. If the release button is not

held down sufficiently, the tubing cannot be

withdrawn.

3)To reuse the tubing, remove the previously

lodged portion of the tubing.If the lodged portion

is left on without being removed, it may result in

air leakage and make the removal of the tubing

difficult.

(2)Connection of the metal rod accessories

Do not use tube, resin plug, reducer, etc. after

connecting a fitting with a metal rod (KC series,

etc.) to a One-touch fitting. This can cause the

disconnection of tube.

(3)When mounting the tube, resin plug or metal

rod, do not press the release button.

Do not press the release button unnecessarily

before mounting tubing, resin plugs and metal

rods. This can cause the disconnection of tube.

(1)When connecting piping to the

One-touch fitting, use a pipe length

with sufficient margin, in

accordance with the piping

conditions shown in Figure 1.

Also, when using a tying band, etc.,

to bind the piping together, make

sure that external force does not

come to bear on the fitting.

(see Figure 2)

Warning

(1)Type of fluids

Please consult with SMC when using the

product in applications other than compressed

air.

(2)When there is a large amount of drainage

Compressed air containing a large amount of

drainage can cause the malfunction of

pneumatic equipment.An air dryer or water

separator should be installed upstream from

filters.

(3)Drain flushing

If condensation in the drain bowl is not emptied

on a regular basis,the bowl will overflow and

allow the condensation to enter the compressed

air lines.This causes the malfunction of

pneumatic equipment.If the drain bowl is difficult

to check and remove, the installation of a drain

bowl with an auto drain option is recommended.

For compressed air quality,refer to SMC catalog

"Compressed Air Purification System".
