Introduction
IRV10,10A,20,20A vacuum regulator is an apparatus to adjust vacuum pressure (negative

（Note1）This varies with pressure on vacuum pump side.
（Note2）For vacuum regulators with a pressure gauge, the pressure gauge will be damaged if
positive pressure is supplied. In the event that positive pressure is applied, the vacuum
regulator will not be damaged, however, the main valve will open and positive pressure will
enter the vacuum pump. This may cause malfunction of the vacuum pump. The vacuum
regulator cannot positive pressure.
（Note3）Taking air from atmosphere all the time.

２.Construction and Operating Principle
By turning handle① clockwise, force of set spring② pushes down diaphragm③ and main valve④ so
that VAC. Pressure side and SET. Pressure side are connected, which increases vacuum on
SET. Pressure side (become closer to absolute vacuum).
Vacuum pressure on SET. Pressure side passes air pass, goes to vacuum chamber⑥ and acts
on the top of diaphragm③ . This pressure opposes compression force of set spring② and
becomes SET. Pressure.
When vacuum SET. Pressure becomes higher than the set value (closer to absolute vacuum),
balance of set spring② and SET. Pressure in vacuum chamber⑥ is lost. Because of this,
diaphragm③ is pushed up so that main valve④ closes and atmosphere suction valve⑤ opens.
Atmosphere flows in SET. Pressure and becomes SET. Pressure when compression force of set
Spring② balances with SET. Pressure.
When vacuum of SET. Pressure becomes lower than the set value (closer to atmospheric
pressure), balance of set spring② and SET. Pressure in vacuum chamber⑥ is lost, and diaphragm③ is
pushed down. Atmosphere suction valve⑤ closes and main valve④ opens, and air is sucked to VAC.
Pressure side. It becomes SET. Pressure when compression force of set spring②
balances with SET. Pressure.

４.Specific Product Precautions
Warning
Handling
(1)If a possible danger of system is expected when vacuum pressure is
Decreased by service interruption and/or vacuum pump trouble, provide
the system with a safety circuit to avoid such a danger.
(2)If a possible danger of system is expected when vacuum regulator
fails, provide the system with a safety circuit to avoid such a danger.
(3)Keep the specified tightening torque for mounting
Excessive torque can damage the mounting screws and product body.
And insufficient torque can cause the threaded parts to loosen.

Caution
Handling
(1) Reduce the set pressure to zero(atmospheric pressure) for removing the plug
when additionally mount the pressure gauge and pressure switch.

Mounting of pressure gauge or pressure switch
1) Confirm the VAC side and SET side of the product, and insert the pressure
gauge or pressure switch completely (until flush with the product surface)into the
preferred hexagon gauge port.
Insert the clip to the left side of the product completely as shown in the figure.
2) After insertion, check to ensure the pressure gauge does not come off.
This is the end of the mounting procedure for the summarized
piping specification.

3) 4)
Note) When the pressure gauge or pressure switch is removed, be sure to remove
the clip straight.
The body is made of resin, so never apply torque.
(2) Do not remove the screw on the body with negative pressure applied.
(3) Reduce the set pressure to zero(atmospheric pressure) and shut off the vacuum
pump pressure completely for removing the guide for inspection.
(4) One touch fitting is cassette type for easy replacement. One-touch fitting is set by clip
inserted as drawing below. To replace the fitting, remove the clip with flat blade driver.
Then, insert one-touch fitting until it contact to the end, and insert the clip to its original
position.
Note1) Before replacement, ensure that VAC.SET pressure is not applied and exhaust inside
pressure completely. Operation with pressure applied is dangerous.
Note2) To pull out the clip, pull it out slowly supporting with hand. The clip may pop out and
dangerous if pulling the clip with force.
Note3) After ensuring the replacement part is inserted to the end, insert the clip to the end.
If the clip is not inserted completely, it will come off.
Note4) To insert elbow type one-touch fitting, hold the fitting with hand during inserting the
tube. Inserting the tube without holding the body applies excess force to blocks and
one-touch fitting and it leads to cause air leakage and damage.

Caution
Environment
(1)Do not use the product in an environment where the product is directly
exposed to corrosive gases, chemicals, salt water or steam.
(2)Do not mount the product in a location where it is subject to strong vibrations
and/or shocks.
(3)Use this vacuum regulator in a location free from dirt since this product
sucks atmosphere all the time.
(4)When the product is directly exposed to sunlight, provide a protective cover.
(5)When heat source is around the product, shut off radiant heat.
Caution
Vacuum Source
(1) This vacuum regulator does not control pressure by connecting with the
exhaust side of the vacuum pump.
(2)Note that ejector should not be used as ”vacuum source” since its flow rate is less
than this vacuum regulator.
Caution
Air
(1) Contact SMC when using the product in applications other than
Compressed air.
(2) Do not use air containing chemicals, synthetic oils with organic solvents,
Salinity and corrosive gases.
Caution
Operation
(1) Connect vacuum pump to the port indicated by “VAC”(shown in upper
Right of the port).
(2) Pressure changes ”atmospheric pressure→vacuum pressure” by turning
the handle clockwise and “vacuum pressure→atmospheric pressure” by
turning the handle counterclockwise.
(3)Pressure cannot be controlled if the air intake hole (hole on the side of the
body) is blocked. Do not block the air intake hole by hand or with an object
during pressure adjustment.
(4)To lock the handle after pressure setting, push the handle until orange
Mark below is hidden and it clicks. To unlock the handle, pull the handle
Until the orange make is seen and it clicks.
(5)Maximum settable vacuum pressure is affected by the atmospheric pressure where
the vacuum regulator is used. Atmospheric pressure varies depending on the
altitude and weather. Actual maximum settable vacuum pressure may not reach the
value in the specification.
(6)When vacuum pump capacity is relatively small or piping ID is small, large
fluctuation of set pressure (variation range in pressure when flowing from
zero) may be the result. In this case, change the vacuum pump or piping
- 12 -
diameter. If the vacuum pump may not be replaced, add a tank (capacity
of the tank depends on the operating conditions) on VAC side.
(7)Note that pressure response time after valve (solenoid valve) opening/
closing is affected by internal volume of the setting side (including piping
volume). In addition, capacity of vacuum pump affects the response time.
(8)As the vacuum regulator intakes atmospheric pressure all the time, the vacuum
pressure cannot be maintained if the vacuum pump or valve is stopped.
If vacuum pressure needs to be retained, it is necessary to continuously run the
vacuum pump.
(9)The set pressure may vary depending on the elapsed time and change in ambient
temperature after pressure setting. If the setting value varies, adjust with the
handle.
(10)If the directional control valve (solenoid valve, mechanical valve etc.) is mounted
and switched ON-OFF repeatedly for a long time, the set pressure may vary. If the
setting value varies, adjust with the handle.
(11) If there is a possibility that the vacuum regulator takes in the dust and water
droplets in the ambient environment through the SET port of the vacuum regulator,
install a vacuum filter or a vacuum drain separator to avoid the entry of these.
(12)There may be pulsation or noise depending on the pressure conditions, piping
conditions and ambient environment. In this case, it is possible to improve the
problem by changing the pressure conditions and piping conditions. If the problem
is not improved, contact your SMC sales representative.
(13) If pressure gauge is used in the direction as Figure 1, it may cause
displacement from zero point. Therefore, be sure to use pressure gauge in the
Direction as Figure 2
