Panel-cut for pressure gauge is not necessary.
In the case of panel mounting, the number of holes for taking out the products (pressure
gauge plus regulator handle parts) can be reduced into one location. By changing the
angle of pressure gauge, the internal volume of a panel can be used effectively.
Mounting example: In the case of aligning three ARG30s in line.

Specific Product Precautions
Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for F.R.L. Precautions.
Piping
Warning
Selection
Caution
1. When mounting a check valve, make sure the arrow (IN side)
points in the correct direction of air flow.
Selection
Warning
1. Float type auto drain
Operate under the following conditions to avoid malfunction.
<N.O. type>
• Operating compressor: 0.75 kW (100 l/min (ANR)) or more.
When using 2 or more auto drains, multiply the value above
by the number of auto drains to find the capacity of the
compressors you will need.
For example, when using 2 auto drains, 1.5 kW (200 l/min
(ANR)) of the compressor capacity is required.
• Operating pressure: 0.1 MPa or more.
<N.C. type>
• Operating pressure for AD27: 0.1 MPa or more.
• Operating pressure for AD37/47: 0.15 MPa or more.
2. Use a regulator or filter regulator with a back flow mechanism
when mounting a 3 port valve for residual pressure release on
the IN side to ensure the release of the residual pressure.
Otherwise, residual pressure will not be fully released.
1. Mounting a 3 port valve for residual pressure release on the IN
side of the lubricator can cause lubricant to back flow. Take
measures to prevent lubricant from splashing by installing a
filter on the EXH port.
2. An F.R.L. unit shipped from the plant has its model number
labeled. However, components that are combined together
during the distribution process do not have a label on them.
AC
Air Supply
AF
Caution
1. Use an air filter with 5 μm or less filtration rating on the inlet
side of the valve to avoid any damage to the seat caused by
dust when mounting a 3 port valve for residual pressure
release on the inlet side.

Warning
1. Releasing the inlet pressure does not
mean that all residual pressure is released
(the outlet pressure cannot be released).
When releasing residual pressure, use a

Mounting and Adjustment
e
i
Warning
1. Set the regulator while verifying the
displayed values of the inlet and outlet
pressure gauges. Turning the regulator
handle excessively can cause damage to
the internal parts.
2. Do not use tools on the pressure regulator
handle as this may cause damage. It must
be operated manually.
o
u
B
Caution
1. Be sure to unlock the handle before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can cause
damage to the handle and the outlet
pressure may fluctuate.
• Pull the pressure regulator handle to
unlock. (You can visually verify this with
the “orange mark” that appears in the
gap.)
• Push the pressure regulator handle to
lock. When the handle is not easily
locked, turn it left and right a little and
then push it (when the handle is locked,
the “orange mark”, i.e., the gap will
disappear).

Example 2)
When the air supply is cut off and
releasing the inlet pressure to the
atmosphere, the residual pressure release
of the outlet side can be ensured for a
safety purpose.

Warning
1. Set the regulator while verifying the
displayed values of the inlet and outlet
pressure gauges. Turning the regulator
handle excessively can cause damage to
the internal parts.
2. Do not use tools on the pressure regulator
handle as this may cause damage. It must
be operated manually.

Caution
1. Be sure to unlock the handle before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can cause
damage to the handle and the outlet
pressure may fluctuate.
• Pull the pressure regulator handle to
unlock. (You can visually verify this with
the “orange mark” that appears in the
gap.)
• Push the pressure regulator handle to
lock. When the handle is not easily
locked, turn it left and right a little and
then push it (when the handle is locked,
the “orange mark”, i.e., the gap will
disappear).
Orange mark
When the inlet pressure (P1) is higher than the regulating pressure, the check valve
w closes and operates as a normal regulator (Figure 1).
When the inlet pressure (P1) is shut off and released, the check valve w opens and
the pressure in the diaphragm chamber q is released into the inlet side (Figure 2).
This lowers the pressure in the diaphragm chamber q and the force generated by the
pressure regulator spring e lifts the diaphragm. Valve r opens through the stem,
and the outlet pressure is released to the inlet side (Figure 3).
Maintenance
Warning
1. When using the regulator between a
solenoid valve and an actuator, check the
pressure gauge periodically.
Sudden pressure fluctuations may shorten
the durability of the pressure gauge.

Specific Product Precautions
Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for F.R.L. Precautions.
Mounting and Adjustment
Selection
Warning
1. Residual pressure release (outlet
pressure release) is not completed by
releasing inlet pressure. To release
residual pressure, use a filter regulator
with a back flow mechanism.
Maintenance
Warning
1. Replace the element every 2 years or
when the pressure drop becomes 0.1
MPa, whichever comes first, to prevent
damage to the element.
426
Warning
1. Set the regulator while checking the
displayed values of the inlet and outlet
pressure gauges. Turning the handle
excessively can cause damage to the
internal parts.
2. Do not use tools on the pressure
regulator handle as this may cause
damage. It must be operated manually.
Caution
1. Be sure to unlock the handle before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can
cause damage to the handle and the
outlet pressure may fluctuate.
• Pull the pressure regulator handle to
unlock. (You can visually verify this
with the “orange mark” that appears in
the gap.)
• Push the pressure regulator handle to
lock. When the handle is not easily
locked, turn it left and right a little and
then push it (when the handle is
locked, the “orange mark” will disappear).

When the inlet pressure (P1) is higher than the regulating pressure, the check valve w closes and operates as a
normal regulator (Figure 1).
When the inlet pressure (P1) is shut off and released, the check valve w opens and the pressure in the diaphragm
chamber q is released into the inlet side (Figure 2).
This lowers the pressure in the diaphragm chamber q and the force generated by the pressure regulator spring e
lifts the diaphragm. Valve r opens through the stem, and the outlet pressure is released to the inlet side (Figure 3).
Specific Product Precautions
Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for F.R.L. Precautions.
Maintenance
Warning
1. Replace the element every 2 years or
when the pressure drop becomes 0.1
MPa, whichever comes first, to prevent
damage to the element.
Mounting and Adjustment
Warning
1. Set the regulator while checking the
displayed values of the inlet and outlet
pressure gauges. Turning the handle
excessively can cause damage to the
internal parts.
2. Do not use tools on the pressure
regulator handle as this may cause
damage. It must be operated manually.
Caution
1. Be sure to unlock the handle before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can
cause damage to the handle and the
outlet pressure may fluctuate.
• Pull the pressure regulator handle to
unlock. (You can visually verify this
with the “orange mark” that appears in
the gap.)

• Push the pressure regulator handle to
lock. When the handle is not easily
locked, turn it left and right a little and
then push it (when the handle is
locked, the “orange mark” will disappear).

Specific Product Precautions
Be sure to read before handling.
Refer to front matters 42 and 43 for Safety Instructions and pages 287 to 291 for F.R.L.
Precautions.
Procedure for replacing or changing the mounting angle of a pressure gauge
Warning
When replacing a pressure gauge and/or changing the mounting angle, release the inlet and outlet pressure completely. It is dangerous to replace the pressure gauge or change the mounting angle while it is under pressure.
5. Setting the pressure gauge
1. Advance preparation
Keep the handle unlocked and completely loosened. The unlocked condition of the handle can be visually confirmed by
the “Orange line” shown near the bottom of the handle.
Note 1) When the pressure gauge cannot be easily positioned,
slightly rotate it. (The cog from the planet gear of the
pressure regulator guide may be caught vertically in the
cog from the sun gear
which is mounted and
integrated with the
pressure gauge)
Note 2) Position the pressure
gauge to the very bottom.
Note 3) Attached to the tip of
the pressure gauge is
an O-ring with grease
applied to it. Please

Orange mark
After the mounting angle is adjusted as required, hold the outer edge of the pressure gauge dial and gently press down.
For reference, the required clearance between the bottom of
the dial and the top of the pressure regulator guide is shown
in table 1.
2. Removing the handle
To remove the handle, align the mark on the handle and
the mark on the bonnet and then pull the handle.

3. Removing the clip
When the mark on the bonnet and the mark on the pressure regulator guide are alligned, the clip can be seen from
the side view of the bonnet. The clip can be picked and removed with tweezers.
∗ When adjusting the mark, turn the pressure regulator guide
clockwise for adjustment.

4. Removing the pressure gauge
Pull the pressure gauge out by holding the outer edge of the
dial.
∗ Do not touch the internal mechanical portion (shown inside
the dotted box). Accuracy of the pressure gauge may be
adversely affected.
6. Setting the clip
Insert the clip in the side of the bonnet when the mark on
the pressure regulator guide and the mark on the bonnet
are aligned. When inserting and setting the clip, use an instrument with a narrow tip, such as tweezers.
Note 1) The clip is slightly tapered towards its tip to prevent it from
being released. Set the clip by slightly opening its tip.
Note 2) When the clip cannot easily be set, the cause may be as
follows:
(1) The pressure regulator screw might have been in a lower
position than then the current one. (The pressure regulator screw may reach a lower position if the pressing force
of the pressure regulator screw is excessively applied.
This occurs because there is a clearance between the
pressure regulator nut and pressure spring, when the
pressure regulator screw is loosened completely.)
(2) The pressure gauge is not firmly set.
Countermeasures ..... Refer to 5 “Setting the pressure
gauge”.
