Datasheet

Operating Environment
1. Do not use in an atmosphere having corrosive gas-
es, chemicals, sea water, water, water steam, or
where there is direct contact with any of these.
2. Do not use in a place subject to heavy vibration
and/or shock.
3. Do not use in an environment where flammable gas
or explosive gas exists. Usage may cause a fire or
explosion. The products do not have an explosion
proof construction.
4. The valve should not be exposed to prolonged sun-
light. Use a protective cover.
5. Remove any sources of excessive heat.
6. In locations where there is contact with spatter from
water, oil, solder, etc., take suitable protective mea-
sures.
Warning
Air Supply
1. Type of fluids
Please consult with SMC when using the product in applica-
tions other than compressed air.
2. When there is a large amount of drainage.
Compressed air containing a large amount of drainage can
cause malfunction of pneumatic equipment. An air dryer or
water droplet separator should be installed upstream from
filters.
3. Drain flushing
If condensate in the drain bowl is not emptied on a regular ba-
sis, the condensate will overflow and allow it to enter the com-
pressed air lines. This will cause a malfunction of pneumatic
equipment. If the drain bowl is difficult to check and remove,
installation of a drain bowl with an auto drain option is recom-
mended.
Refer to “SMC Air Preparation System” for further details on com-
pressed air quality.
4. Use clean air.
Do not use compressed air that contains chemicals, synthetic
oils including organic solvents, salt or corrosive gases, etc., as
it can cause damage or malfunction.
Warning
Design
Warning
1. Confirm the specifications.
Products represented in this catalogue are designed only for
use in compressed air systems (including vacuum).
Do not operate at pressures or temperatures, etc., beyond the
range of specifications, as this can cause damage or malfunc-
tion. (Refer to the specifications.)
Please contact SMC when using a fluid other than com-
pressed air (including vacuum).
We do not guarantee against any damage if the product is
used outside of the specification range.
2. Modification prohibited
Do not make any modifications, including additional machin-
ing. It may cause human injury and/or an accident and will
void the warranty.
Other Tube Brands
Caution
1. When tubing of brands other than SMC’ s are used,
verify that the tubing O.D. satisfies the following ac-
curacy;
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 meet these outside diameter
tolerances. It may not be possible to connect them, or they
may cause other trouble, such as air leakage or the tube pull-
ing out after connection.
2. Connecting products with metal rods
After connecting the products with metal rods (Series KC, etc.)
to the One-touch fittings, do not use tubes, resin plugs or re-
ducers, etc. These may come off the fittings.
