Рабочие Пилотный Условия по Функционирование Пример соединения цилиндра
условия клапан давлениям с пневмодросселями
При включении пилотного клапана (управляющего пневмораспределителя) (2)
(электрическом включении или от ручного вспомогательного рычага)
вспомогательный воздух отжимает поршень А (3) вниз и главный клапан (1)
открывается. При этом закрывается переход к порту деаэрации R.
Поток сжатого воздуха поступает через игольчатый клапан (7) от Р к А.
Когда Р 1/2 Р , открывается поршень В (5). В результате этого Р
немедленно возрастает до значения Р .
АР А
Р
?
Поршень В остается открытым, скорость хода поршня цилиндра определяется
только пневмодросселем.
При отключении пилотного клапана (2) поршень А (3) и главный клапан (1)
поджимаются вверх пружиной (4), переход к порту деаэрации R открывается.
Одновременно прерывается поток сжатого воздуха от входа Р. В результате
разницы давлений на обратном клапане (6) этот клапан отжимается вниз и
происходит деаэрация повышенного давления вторичного контура через
переход R.
Принцип действия/регулировка иголь атого клапана
В-В
Регулировка игольчатого клапана
Игольчатый клапан регулируется с помощью отвертки. Вращением по часовой стрелке
достигается уменьшение расхода, вращением против часовой стрелки обеспечивают
повышение расхода (согласно диаграмме характеристики расхода).

Since piston B holds the fully open condition, during normal operation the
cylinder's speed will be controlled by the usual meter-out control.
When pilot valve is turned OFF, spring pushes piston A and main valve
upward and opens R port while shutting off the air supply from P port. The
pressure difference generated at this time opens check valve and the residual
pressure on the A port side is quickly exhausted from R port.
When 1/2 PP ≤PAafter the cylinder rea-
ches , piston B fully opens and PAin-
creases rapidly as shown from to and
becomes the same pressure as PP.
When pilot valve is turned ON by ener-
gization or manual override, the pilot air
pushes piston A and main valve
downward and opens main valve while
R port closes simultaneously. The air from
P port moves to needle valve , where its
flow is adjusted, and flows to A port. The
meter-in control of needle valve slowly
moves the cylinder from to .

Safety Instructions
These safety instructions are intended to prevent a hazardous situation and/or
equipment damage. These instructions indicate the level of potential hazard by a
label of "Caution", "Warning" or "Danger". To ensure safety, be sure to
observe ISO 4414
Note 1),JIS B 8370 Note 2)
and other safety practices.
1. The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility for the
specific pneumatic system must be based on specifications or after analysis and/or tests to meet your
specific requirements.
2. Only trained personnel should operate pneumatically operated machinery and
equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of
pneumatic systems should be performed by trained and experienced operators.
3. Do not service machinery/equipment or attempt to remove components until
safety is confirmed.
1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of
safe locked-out control positions.
2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply
pressure for this equipment and exhaust all residual compressed air in the system.
3. Before machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod,
etc. (Bleed air into the system gradually to create back pressure.)
4. Contact SMC if the product is to be used in any of the following conditions:
1. Conditions and environments beyond the given specifications, or if product is used outdoors.
2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or
safety equipment.

1. Actuator drive
When a component such as a solenoid valve or actuator is to
be driven using this product, take appropriate measures to pre-
vent potential danger caused by actuator operation.
2. Holding of pressure
Since the products are subject to air leakage (allowed), they
cannot be used for applications such as holding pressure in a
pressure vessel.
3. Maintenance space
The installation should allow sufficient space for maintenance
activities.
Selection
Design
Warning 1. Leakage voltage
Particularly when using a C-R element (surge voltage suppres-
sor) for protection of the switching element, take note that lea-
kage voltage will increase due to leakage current flowing
through the C-R element, etc.
2. Low temperature operation
Although the valve can be operated at a temperature as low as
0°C, measures should be taken to avoid solidification or free-
zing of drainage and moisture, etc.
Caution
AC coil is 20% or less of rated voltage.
DC coil is 3% or less of rated voltage.

1. Confirm the specifications.
The products presented in this catalog are designed only for
use in compressed air systems. Do not operate at pressures or
temperatures, etc., beyond the range of specifications, as this
can cause damage or malfunction.
(Refer to specifications.)
Contact SMC when using a fluid other than compressed air.
2. Extended periods of continuous energization
Contact SMC if valves will be continuously energized for
extended periods of time.
3. Operation of closed centre solenoid valves
When closed center solenoid valves are used, or when used on
an actuator with a load factor of 50% or more, jumping
(lurching) cannot be prevented even if this product is used.
4. Using a regulator on the secondary side
When mounting a regulator on the secondary side (A port side),
use a residual pressure relief regulator (AR2550 to 4050) or a
check type regulator (AR2560 to 6060).
With a standard regulator (AR1000 to 6000), the secondary
side pressure may not be released when this valve is
exhausted.
5. Operation of secondary side solenoid valves
To operate solenoid valves mounted on this product's
secondary side (A port side), first confirm that the secondary
side's pressure (P) has increased to become equal to the
primary side's pressure (P).
6. Operation
The residual pressure release function of this product is for
emergency use only; therefore, avoid operation in the same
manner as ordinary 3 port valves.
7. Using a lubricator
If mounting a lubricator, mount it on the primary side (P port
side), of this product. If mounted on the secondary side (A port
side), back flow of oil will occur and may spurt out of the valve's
R port.
8. Operation for air blowing
This product cannot be operated for air blowing due to the me-
chanism that switches the main valve to be fully open after the
secondary side's pressure increases to approximately 1/2 of the
primary side.
Selection
Warning
1. If air leakage increases or equipment does
not operate properly, stop operation.
After mounting or maintenance, etc., connect the compressed
air and power supplies, and perform appropriate function and
leakage tests to confirm that the unit is mounted properly.
2. Instruction manual
Mount and operate the product after reading the manual care-
fully and understanding its contents. Also keep the manual
where it can be referred to as necessary.
3. Painting and coating
Warnings or specifications printed or pasted on the product
should not be erased, removed or covered up.
Furthermore, contact SMC before paining resin parts, as this
may cause adverse effects depending on the solvent.
Mounting
Warning
1. To perform the initial speed adjustment of a
secondary side actuator, supply air from this
valve's primary side and turn ON the pilot
valve. Then, rotate the needle counter clock-
wise from the fully closed condition.

Caution
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and ot-
her debris from inside the pipe.
2. Wrapping of pipe tape
When connecting pipes and fittings, etc., be sure that chips
from the pipe threads and sealing material do not get inside the
valve.
Further, when pipe tape is used, leave 1.5 to 2 thread ridges
exposed at the end of the threads.
Piping
Caution
3. Tighten threads with the proper tightening
torque.
When screwing fittings into valves, tighten with the torques gi-
ven below.

1. The valve has been lubricated for life at the factory, and
does not require any further lubrication.
2. In the event that it is lubricated, use Class 1 turbine oil (wit-
hout additives), ISO VG32.
However, once lubrication is applied it must be continued,
as the original lubricant may be eliminated leading to mal-
function.
Contact SMC regarding Class 2 turbine oil (with additives),
ISO VG32.
Lubrication
Caution
4. Connection of piping to products
When connecting piping to a product, refer to its instruction
manual to avoid mistakes regarding the supply port, etc.
5. F.R.L. module combination
When connecting to a modular F.R.L. combination (AC2000 to
6000), select one of the spacers, which are included. (Refer to
page 6 for details.) However, modular combination with AC4000-
06 is not possible.
Furthermore, connect soft start-up valves to the secondary side
of the F.R.L. combination.
6. Primary side piping conditions
The nominal size of the piping material's or equipment's bore
should be equal to or larger than the soft start-up valve's port
size. The composite effective area of the primary side's (P port
side's) piping or equipment should be equal to or larger than the
values below.
When the piping is restricted or the supply pressure is
insufficient, the main valve will not switch and air leakage may
occur from the R port.

Do not use compressed air which contains chemicals, synthetic
oils containing organic solvents, salts or corrosive gases, etc.,
as this can cause damage or malfunction.
Air Supply
Warning
1. Install air filters.
Install air filters close to valves at their upstream side. A filtra-
tion degree of 5µm or less should be selected.
2. Install an after-cooler, air dryer or water sepa-
rator, etc.
Air that includes excessive drainage may cause malfunction of
valves and other pneumatic equipment. To prevent this, install
an after-cooler, air dryer or water separator, etc.
Caution
1. Perform maintenance procedures as shown
in the instruction manual.
If handled improperly, malfunction or damage of machinery or
equipment may occur.
2. Equipment removal and supply/exhaust of
compressed air
When equipment is removed, first confirm that measures are in
place to prevent dropping of work pieces and run-away of
equipment, etc. Then cut the supply pressure and power, and
exhaust all compressed air from the system using its residual
pressure release function.
3. Low frequency operation
Valves should be switched at least once every 30 days to pre-
vent malfunction. (Use caution regarding the air supply.)
4. Manual override operation
When the manual override is operated, connected equipment
will be actuated. Confirm safety before operating.
Maintenance
Warning
1. Drainage removal
Remove drainage from air filters regularly. (Refer to specifica-
tions.)
Caution
1. Do not use valves in atmospheres of corrosi-
ve gases, chemicals, salt water, water or
steam, or where there is direct contact with
any of these.
2. Do not use in an explosive atmosphere.
3. Do not use in locations subject to vibration or
impact.
4. A protective cover, etc., should be used to
shield valves from direct sunlight.
5. Shield valves from radiated heat generated
by nearby heat sources.
6. Employ suitable protective measures in loca-
tions where there is contact with water dro-
plets, oil or welding spatter, etc.
7. In a dusty environment or when valve swit-
ching noise is intrusive, take measures for
the prevention of dust entry and for noise re-
duction, such as mounting a silencer on the
R port.
