*1: As G and NPT threads can also be used for piping port threads, contact CKD for details.
*2: The
‌
ethylene propylene rubber seal combination (Item D P/R) cannot be used with air. (Compressed air contains oil, and ethylene propylene rubber is not oil-resistant.)
*3: For the thermal class B diode integrated coil, the AC power supply voltage is converted into DC coil voltage by the diode.
*4: When Item D is C, F, K or N, the manual override (Item G A or AB) is not available.
*5: ‌Other voltages as below are also available. Contact CKD for details.

CAUTION
■ Explosive
gas and explosion-proof enclosure
The degree of explosive gas danger is classified according
to the group and temperature grade. Gases with equivalent
risk are grouped into one group, and explosion-proof
structure standards are set for each group.
Codes to indicate the type, group and temperature grade
must be indicated in this order on the electrical components
of explosion-proof structures. These codes indicate which
group and temperature grade the electrical components have
been manufactured for, and which gases can be used. For
the example of explosion-proof solenoid valve of Exd II BT4:
Ex d IIB T4
Temperature class T4
Group II B
Pressure and explosion
proof structure
Table 2 indicates the classification of gases with a danger
category of Group II B and Grade T4 temperature that are
compatible with the product. Less dangerous gases are also
listed that are guaranteed to be explosion-proof.
Temperature grade refers to the degree of ignition risk, and
is classified into six grades according to the ignition point. It
defines the maximum surface temperature of the device
corresponding to each grade (Table 1).
Higher numbers indicate a higher risk that the gas will ignite at low
igniting temperatures. Group refers to the risk of fire leaping to the
exterior from small gaps. The level is classified into three grades
according to the gap, and the codes shown in Table 1 are used. It
can be said that this group expresses the classification by size of the
explosive energy. Lower maximum safety clearance indicates more
dangerous gases with higher explosive energy that can cause
flames to pass through small gaps and leap to the exterior.

zone
Situations where explosive gases and air mix at a high
enough level to cause an explosion or fire are called “danger
zones”. These zones are classified into Zones 0, 1 and 2
according to the time and frequency at which the dangerous
atmosphere is reached. The explosion-proof structure that
can be used is determined according to these classes.
● Zone 0 (explosion-proof general purpose valve EX Series
cannot be used)
Zones where a dangerous atmosphere is or could be
continuously generated, and where the concentration of
explosive gas is maintained continuously or for long periods
above the lower limit for explosions.
Example a: ‌The open space above a flammable liquid inside
a container or tank.
b: Inside a combustible gas container or tank.
c: Near flammable liquid in an open container.
● Zone 1
(1) Zones where explosive gas could accumulate to a
dangerous concentration during operations such as the
opening/closing of the lid for removing the product or
operation of the safety valve, etc.
(2) Zones where explosive gases are likely to accumulate to
dangerous concentrations during repair or maintenance or
due to leakage, etc.
● Zone 2
(1) Zones where combustible gases or flammable liquids are
regularly handled, but where the gases and liquids are
sealed in a vessel or equipment, and where the gases and
liquids could leak to dangerous concentrations only if the
vessel or equipment breaks by accident or due to
misoperation.

WARNING
1 Working fluids
■
(1) When
‌
using this valve for dry air or inert gas, the life can be
shortened considerably due to wear.
(2) ‌This valve cannot be used for maintaining vacuum. Consult
with CKD when the vacuum needs to be maintained.
CAUTION
1 Continuous energizing
■
Use the NO pressurization type when using the 3-port valve in a
continuously energized state with the NO port pressurized. When
continuously energizing the universal or NC pressurization type,
use a fluoro rubber seal.
2 Suction sound
■
With the AC voltage specifications, a loud suction sound may be
heard momentarily after energizing. To avoid a suction sound,
select a coil with a diode or the DC voltage model. The suction
sound volume will be reduced.
■ As a guide, use a wire with a nominal cross section of 1.04
to 2.63 mm2 and the following allowable temperature.
AB□EX4, AG4□EX4, AP□□EX4, AD□□EX4, ADK1□EX4:
Allowable temperatures 80°C or higher
AB□EX2, AP□□EX2: Allowable temperatures 100°C or
higher
Make sure that excessive force is not applied to the lead
wire.
● I‌nstall wiring in accordance with JIS explosion-proof
guidelines.
● Remove the terminal box cap and install the wiring. Use the
tools specified in the following diagram for crimping the
crimp terminals upon wiring. After finishing wiring, securely
tighten the terminal box cap.

CAUTION
1 Piping
■
(1) ‌Always hold the socket with a wrench, etc., when piping the
NO side of the 3-port valve.
(2) ‌If the pipe vibrates when the solenoid valve is opened and
closed, securely fix the piping.
(3) ‌For steam fluids, steam generated from a boiler will contain a
large amount of drainage. Always install a drain trap.
(4) ‌When passing steam, the make-up water in the boiler will
contain substances such as “calcium salt” and “magnesium
salt”. As these substances will react with oxygen and carbon
dioxide, and cause scales and sludge to form, always install a
“water softener” and a filter for steam.
(5) ‌When AP/AD/ADK and the regulator are directly coupled, the
parts could mutually vibrate, causing resonance and
chattering.
(6) ‌If the piping cross-sectional area on the fluid inlet is reduced,
the operation may become unstable due to differential
pressure failure during valve operation. For the fluid inlet, use
piping of a piping size that matches the port size of the valve.
Do not use a needle valve.

When using the product
CAUTION
1 Sudden leakage
With the pilot operated or pilot kick 2-port valve, if the
pressure is suddenly applied when the pump starts while the
valve is closed, the valve may open for an instant causing
fluid to leak. Caution is required during use.
2 Operation
Do not apply back pressure. This could lead to malfunction.
3 Manual operation
■
When using a product with a manual override, follow the
operations below:
Opening: ‌Insert a flathead screwdriver into the slit on the manual
adjustment shaft, and turn it approx. 120° to the right
or left. The plunger will rise and the valve will open.
(For the 3-port valve, the NC side valve seat will open
and the NO side valve seat will close.)
The open state is held even when the screwdriver is
removed.
Always return the valve to the original position after
use.
Closing : ‌From the open position, turn the manual adjustment
shaft so that the slit is returned to the perpendicular
position, which will lower the plunger and close the
valve. (For the 3-port valve, the NC side valve seat will
close and the NO side valve seat will open.) (Refer to
the figure below)

Main line
An air compressor is normally used to make
compressed air by compressing the
atmosphere. The compressed air will be
highly contaminated with a high content of
impurities such as water vapor and small
particles too small to see which were
originally in the ambient air, but now in high
concentrations in proportion to the
compression ratio. In some types of
lubrication air compressor, lubricant is
oxidized by compression heat or frictional
heat to form oil oxide, or may generate solid
substance such as carbon and tar, etc.
Oil-free air compressors will also generate
carbon particles. These factors make the
compressed air more contaminated.
To remove the impurities in the compressed
air, CKD’s clean air systems offer an
effective and inexpensive means by
arranging the components suitably for a
specific application, including a submicron
filter to remove tar and carbon, a dryer to
remove water vapor, and an oil mist filter to
remove oil oxides and odor.

Precautions for system selection
*1: If
‌ your conditions are different, refer to the specifications in the catalog in order to select
a model.
*2: Use
‌
anti-rust processed materials for piping (zinc plated pipe, lined pipe or stainless
steel pipe). Use stainless steel pipes for ultra dry air.
*3: Always degrease the piping after oil mist filter before use.
*4: Always install the main pipe with a 1/100 slope.
*5: Install a filter immediately before the equipment to be used to remove contaminants
existing in the piping.
