Warning

(1) Confirm the specifications.

This product is designed to be used only in a

compressed air system (including vacuum).

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 to reduce leakage to zero may result in

equipment damage.

(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. Also, depending on

product specifications, there may be variations

in the zero needle rotations position of the flow

rate characteristics.

(5)Sonic conductance (C) and critical

pressure ratio (b) values for products are

representative values.

For controlled flow direction and free flow

direction values the needle is fully open.

(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.

maintenance.

(3)Tighten threads with the proper tightening

torque.

When installing the products, follow the listed

proper torque.

(4)After pushing the knob down to lock,

confirm that it is locked.

It should not be possible to rotate the knob to

the right or to the left. If the knob is pulled

with force, it may break. Do not pull the knob

with excessive force.

(5)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.

Warning

(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 lurching.

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 apply excessive force or shock to

the body or fittings with an impact tool.

It can cause damage or air leakage.

(11)For handling One-touch fittings, refer to

the Fittings and Tubing Precautions.

(12)To install/remove the product, use an

※

G thread (face seal) complies with

ISO16030-2001.

※

Use G external threads with G internal

threads.

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.

Caution

(3) Reuse

①

Normally, fittings with a sealant can be

reused 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, 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

①

Installation of tube

1) Cut the tube perpendicularly, being careful not

to damage the external surface. Use an SMC

tube cutter TK-1, 2, 3, 5 or 6. 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

(0 to 5°) 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.

As a guide for checking if the tubing is pulled

out or not, refer to the following table.

②

Removal 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.

Caution

(2) Connection of the metal rod accessories

Products with metal rods (KC series,

previous KQ series, KN series, KM series,

etc.) cannot be connected to KQ2 series

One-touch fittings. If connected, the metal

rod cannot be retained by the chuck of the

One-touch fitting, and products with metal

rods may project during pressurization,

causing serious personal injury or accident.

Even when products with metal rods can be

connected to other One-touch fittings, do

not use any tube, resin plug, or reducer

after connection. This may cause

releasing.

(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.

(4) When using tubing from a manufacturer

other than SMC, be careful of the tolerance

of the tubing O.D. and tubing material.

1) Nylon tubing

Within ±0.1 mm

2) Soft nylon tubing Within ±0.1 mm

3) Polyurethane tubing Within +0.15 mm,

Within -0.2 mm

Do not use tubing which does not satisfy the

specified tubing O.D. accuracy, or tubing with

an I.D., material, hardness, or surface

roughness that differs from SMC's tubing. It

may cause difficulty in connecting the tubing,

leakage, disconnection of the tubing, or fitting

damage.

When used with tubing other than those from

SMC, due to their properties, the products

listed below are not subject to warranty.

Precautions for One-Touch Tube Fittings

Mounting/ Piping

Mounting/Piping

(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

Use compressed air as the operating fluid.

(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".

Warning

(4) Use clean air

Do not use compressed air that contains

chemicals, synthetic oils that include organic

solvents, salt, corrosive gases, etc., as it can

cause damage or malfunction.

Caution

(1) Install an air filter.

Install an air filter at the upstream side of

valve. Select a filtration rating of 5 µm or

below, or that equivalent to or lower than ISO

8573-1:2010 [6:4:4]

* This rating is equivalent to the rating

produced when an air filter is installed for the

purity class [7:4:4] of the inlet side

compressed air.

(2)Take measures to ensure air quality, such

as by installing an aftercooler, air dryer, or

water separator.

Compressed air that contains a large amount

of drainage can cause the malfunction of

pneumatic equipment, such as flow control

equipment. Therefore, take appropriate

measures to ensure air quality, such as by

providing an aftercooler, air dryer, or water

separator.

(3) Ensure that the fluid and ambient

temperatures are within the specified

range.

If the fluid temperature is 5

℃

or less, the

moisture in the circuit could freeze, causing

damage to the seals or leading to equipment

malfunction. Therefore, take appropriate

measures to prevent freezing.

For compressed air quality, refer to SMC

catalog "Compressed Air Purification

System".

Warning

(1) Do not use in an atmosphere containing

corrosive gases, chemicals, sea water,

water, water steam, or where there is direct

contact with any of these.

(2)Do not expose the product to direct

sunlight for an extended period of time.

(3)Do not mount the product in locations

where it is exposed to radiant heat.
