Operating principle
Working stroke Return stroke
1. The cylinder starts smoothly because jerks are prevented by
meter-in control. 3. To prevent delay due to the pressure gap, air is rapidly
exhausted to decrease the pressure from Dto E, after which
the piston moves at a constant speed. If a speed controller is
used instead of the flow valve, exhausting air will take more
time as illustrated by line D-F, resulting in longer stop time of
the cylinder and a consequent time loss.
4. The cylinder operates at a low pressure required for a return.
2. When the cylinder reaches the stroke end, the quick air charge
by the flow valve rapidly increases the rear side pressure (PH)
from Ato B. If a speed controller is used instead of the flow
valve, charging air will take more time as illustrated by line A-
C, causing delay in the pressure rise.

1. The cylinder speed is adjusted with knobs C, Dand E. First
have all the knobs fully closed and then open them gradually
for adjustment. Turn the knob clockwise to close (decrease the
speed of the piston rod) and counterclockwise to open
(increase the speed of the piston rod).
2. Speed adjustment for the working stroke
The speed is adjusted with the pressure valve and the flow
valve.
Open knobs Cand Egradually until the required speed is
achieved. Make sure that knobs Cand Eare opened by the
same number of rotations.
Note 1) If the piston rod jerks, close knob Euntil the smooth
operation is achieved.
3. Speed adjustment for return stroke
The speed is adjusted with the flow valve.
Open knob Dgradually until the required speed is achieved.
4. Be sure to tighten the lock nut after adjustment.

Adjustment Procedure 1
Pressure adjustment Speed control
Adjustment Procedure 2
1. The fixed set pressure type (-F20) does not require adjustment
because the pressure is fixed at 0.2 MPa for both the pressure
valve and the flow valve.
2. The set pressures of the variable set pressure type pressure
valve and flow valve are adjusted with knob Aand knob B
respectively. Turn the knob clockwise to increase the pressure
and counterclockwise to decrease the pressure.
3. The graduations 1, 2 and 3 correspond to 0.1, 0.2 and 0.3
MPa respectively. Align the bottom end of the knob with the
graduated line for adjustment.
4. Set the same pressure for the pressure valve and the flow
valve (0.2 MPa as the recommended value).
5. The inlet side should be supplied with a pressure which is
higher than the set pressure by 0.1 MPa or more.
6. Cap the valve after adjustment.

Caution
Air Saving Valve Precautions
Be sure to read before handling.
1. Confirm the specifications.
The products appearing in this catalog are designed for use
only in compressed air (included vacuum pressure) systems.
Do not use outside the specified ranges of pressure, tempera-
ture, etc., as this may cause damage or malfunction. (Refer to
specifications.)
Consult SMC if fluids other than compressed air (included va-
cuum pressure) are to be used.
Selection
Warning 3. Drain flushing management
If the air filter drains are not flushed regularly, the condensate
will flow downstream from the drains, resulting in malfunction
of the pneumatic equipment.
In cases where drain flushing will be difficult, use of filters with
auto drain is recommended.
For detailed information on the quality of compressed air, refer
to Best Pneumatics Vol. 4.
4. Types of air
Do not use compressed air containing chemicals, salt, corrosi-
ve gases, synthetic oil which includes organic solvents, etc.,
which may cause damage or faulty operation.
Air Supply
Caution
1. Do not use valves where there is direct contact
with, or in atmospheres of, corrosive gases,
chemicals, salt water, water or steam.
2. Provide shade in locations which receive direct
sunlight.
3. Do not operate in locations where vibration or
impact occurs.
4. Do not operate in locations where the product
is exposed to direct heat radiation from a heat
source at a close distance.
Operating Environment
Warning
1. Maintenance should be performed in accor-
dance with the procedures in the instruction
manual.
Incorrect handling can cause damage or malfunction of
machinery and equipment, etc.
2. Maintenance work
Compressed air can be dangerous if handled improperly.
Element replacement and other maintenance etc., should be
performed by personnel having sufficient knowledge and
experience pertaining to pneumatic equipment, while also
adhering to the product specifications.
3. Drain flushing
Condensate should be flushed from the air filter and other
drains on a regular basis.
4. Pre-maintenance checks
When the product is to be removed, be sure to shut off the
supply pressure, release compressed air in the pipelines and
confirm an atmospheric release condition before proceeding.
5. Post-maintenance checks
After mounting, repair or renovation, supply compressed air
and perform suitable function and leak tests. If an audible leak
is detected or equipment does not operate properly, stop
operation and confirm that mounting is correct.
6. Disassembly and modification is prohibited.
Do not disassemble or modify the main unit.
Maintenance
Warning
1. Types of fluid
This product is designed for use with compressed air. Contact
SMC if a different type of fluid is to be used.
Contact SMC regarding products for general fluids, to confirm
which fluids can be used.
2. A large amount of condensate
Pressurized air containing a large amount of condensate may
cause malfunction of the pneumatic equipment. An air dryer or
water separator should be installed upstream from the filters.
Air Supply
Warning

1. Confirm that the lock nut is not loose.
If the lock nut is loose, there may be dangerous changes in
actuator speed.
2. The number of opening and closing rotations
of the needle valve and adjustment screw
should be adjusted within the range of the
specifications.
Since it has a pull-out stop mechanism, it will not rotate past
the limit. Confirm the number of rotations for the product being
used, as excessive turning of the needle will cause damage.
3. To adjust the speed, start with the needle in
the completely closed position, and then
adjust by opening gradually.
When the needle valve is opening, the actuator may jerk
suddenly creating a dangerous situation.
Moreover, the needle valve is closed by turning clockwise,
and opened by turning counterclockwise. Therefore, the
actuator speed is reduced by turning clockwise and increased
by turning counterclockwise.
When the product is used for an actuator operating vertically,
the actuator may lurch depending on the load. For the
adjustment method, please refer to “Selection and Adjustment”
on page 3 and 4.
4. For installation and removal, tighten the body
B by applying an appropriate wrench to the
two opposite sides of the hexagon.
Using other parts may destroy the valve. For alignment after
installation, rotate body A manually.
5. Do not use universal type fittings at a posi-
tion where they are constantly rotated.
The fittings may be damaged.
6. The valve cannot be used if there are fluc-
tuations of the load.
The piston rod may jerk during operation.
7. In case a closed-center solenoid valve is used,
switch to the center position only after pres-
sure charge inside the cylinder at the stroke
end is completed.
If the pressure charge is insufficient, the piston rod may jerk
after restart.
Installation
Warning
Pressure Valve Series ASR / Flow Valve Series ASQ
Specific Product Precautions
Be sure to read before handling.
1. The product cannot be used as a stop valve,
of which zero leakage is required.
The specifications of the product allow a certain degree of
leakage.
2. Confirm whether PTFE can be used.
The sealing compound contains PTFE (tetrafluoroethylene resin)
powder. Make sure that it will not cause any problem in operation.
3. Keep the set pressure range of the outlet
pressure of the pressure valve within 85%
that of the inlet pressure.
If the value exceeds 85%, the pressure may become unstable,
affected by the fluctuation of the inlet pressure.
Selection
Warning 1.
The proper tightening torque for pipe fittings is as
shown in the table. As a rule, they should be tightened
2 to 3 turns with a tool after first tightening by hand.
Be careful not to cause damage by over-tightening.
Tightening Torque
Caution
1. Installation and Removal of Tubing for One-
Touch Fittings
1) Installation of tubing
(1) Using tube cutters TK-1, 2 or 3, take a tube having no
flaws on its periphery and cut it off at a right angle. Do not
use pinchers, nippers or scissors, etc. The tubing might
be cut diagonally or flattened, making installation
impossible or causing problems such as disconnection
and leakage. Allow extra length for the tubing.
(2) Hold the tubing and push it in slowly, inserting it securely
all the way into the fitting.
(3) After inserting the tubing, pull on it lightly to confirm that it
will not come out. If it is not installed securely all the way
into the fitting, problems such as leakage or disconnection
of the tubing can occur.
2) Removal of tubing
(1) Push in the release button sufficiently, pressing the collar
evenly around its circumference.
(2) Pull out the tubing while holding down the release button
so that it does not pop out. If the release button is not
pressed down sufficiently, there will be increased bite on
the tubing and it will become more difficult to pull it out.
(3) When the removed tubing is to be used again, first cut off
the section of the tubing which has been chewed. Using
the chewed portion of the tube as it is can cause problems
such as leakage or difficulty in removing the tubing.

1. The valve cannot be used if the same pressure is required for
both the working and return strokes.
The pressure valve and flow valve are designed to save air by
the difference in the operating pressure.
2. Install a flow valve on the working side which requires the
cylinder output and a pressure valve on the return side. The
cylinder may not operate if the valves are installed on the
wrong sides.
3. If a closed-centre, exhaust-centre, pressure-centre or perfect
solenoid valve is used and the solenoid valve is set at the
center position, the cylinder may move to the position where
the pressure balance and load balance are achieved.
