2. INSTALLATION
2.1 Environment
WARNING
Consult CKD about the specifications before using the product outside the designated
specifications or for special applications.
Prevent water and cutting oil from splashing onto the product directly.
•If water or cutting oil splashes onto the pilot solenoid valve directly, it may cause the coil to burn
out.
•Although the product provided with a DIN terminal box has a degree of protection equivalent to
IPX5, this does not guarantee a protection against continuous water splash. Protect the product
by installing it under a cover or inside a paneled casing.
•When there is a possibility that the product is subjected to spatters of welding, take proper
protective measures.
Consider measures for dissipating heat generated from a coil.
Appropriate ventilation or heat dissipation measures must be considered if the product is installed
in a control board or if the solenoid coil needs to be energized for a long period.
Do not use the product in the presence of corrosive gas or solvents.
Do not use the product in an environment where corrosive gases such as sulfur dioxide gas or
solvents are present.
Do not use the product in a humid environment.
Condensation may occur due to a change in the temperature.
Do not use an SVB Series valve in an explosive gas atmosphere.
The solenoid valve mounted type SVB Series valve cannot be used in an explosive gas
atmosphere. For use in an explosive gas atmosphere, select an SAB Series valve and install an
explosion-proof type solenoid valve in the pilot air circuit.
CAUTION
Take measures to prevent dusts from entering the valve.
In a dusty environment, install an elbow fitting facing down or a silencer to the pilot air exhaust port
of the valve to prevent dusts from entering.
Use the product in an environment where it is not subject to radiant heat.
Do not paint the product or clean it with water or solvent.
The resin parts can become damaged and this may lead to a failure or malfunction.
•When using in a cold area, take proper measures against freezing.
•The product cannot be used outdoors. Protect the product by installing it inside a cover or a
case.
•Do not use the product in an environment where the valve is subject to vibrations or inertia.

2.2 Unpacking
CAUTION
Do not remove the piping port protector and do not take the product out of the plastic bag
until just before piping.
If the piping port protector is removed or the product is taken out of the plastic bag before ready to
begin piping, foreign matters may enter from the piping ports and cause a failure or malfunction.
•Check that the model number ordered and the model number indicated on the product are the same.
•Check the exterior of the product for any damage.
•When storing the product, keep it packaged in the individual package box to prevent foreign matters
from entering the valve. Take it out of the box when ready to begin piping.
2.3 Mounting
CAUTION
Thoroughly read and understand this Instruction Manual before mounting the product.
Hold the body firmly when handling and mounting the product.
Check for leakage from the pipes after mounting the product and confirm that the product has
been mounted properly.
•There is no restriction on the mounting orientation.
However, for the solenoid valve mounted type SVB Series valve, do not mount the product
with the coil facing down. If the coil is mounted facing down, foreign matters in the fluid will
adhere to the electromagnetic iron core and cause noise and operation faults.
•Secure sufficient space for working safely during maintenance and troubleshooting. (Refer to
the figure below.)
1 Install piping by holding the width across flats section on the valve with a pipe wrench or an
adjustable wrench.

SM-50664-A/4 2. INSTALLATION
11 2018-11-12
2.4 Piping
CAUTION
Secure the product when tightening or piping again.
Secure and support the pipes to prevent the valve from being subjected to pipe loads and
vibrations directly.
Do not apply high pressure suddenly when supplying fluid for the first time after connecting
the pipes.
If the pipes are not secured properly, it may lead to accidents such as a pipe disconnection or a
fluid leakage.
Pipe cleaning
Before piping, flush with air of more than 0.3 MPa to remove foreign matters such as dust, metal powder,
rust, and seal tape.
Removal of foreign matters
Remove foreign matters such as dusts in the fluid to prevent causing an operation fault or leakage.
When the fluid is air, install a filter (maximum allowable particle size is 5 μm) on the primary side of the
valve.
Fluid supply port when piping
Pipe the body side supply ports and the pilot air side supply ports as indicated in the following table.

Seal material
Apply a seal tape or seal material to the screw threads leaving two or more threads at the pipe end
uncovered or uncoated. If the pipe end is fully covered or coated, a shred of seal tape or residue of seal
material may enter inside of the valve and cause a failure.
When using a seal tape, wind it around the screw threads in the direction opposite from the screw
threads and press it down with your fingers to attach it firmly.
When using a liquid seal material, be careful not to apply it to resin parts. The resin parts can become
damaged and this may lead to a failure or malfunction.
Also, do not apply seal material to the internal threads.

Tightening
•When piping to the valve, secure the body with a wrench or a vise.
•When using the solenoid valve mounted type SVB Series valve, do not connect a steel pipe directly to
the pilot solenoid valve. The screws for mounting the solenoid valve may become damaged.
•For the pipe tightening torque, refer to the following tables.

Lubrication
This valve can also be used without lubrication. Although a lubricator is not required, when lubricating,
use Class 1 ISO VG32 turbine oil (additive-free).
An operation fault may occur due to the loss of the initial lubricant if lubrication is not continued. Make
sure to continue lubrication so as not to run out the lubricant.
Measures against drainage of pilot air
Compressed air contains a large amount of drainage such as water, oxidized oil, tar, and foreign matters.
Such drainage may cause a significant reduction in the accuracy of the pneumatic component. Take
measures against drainage (such as dehumidifying with an aftercooler or a dryer, removing foreign
matters with an appropriate filter, or installing a tar removing filter) in order to improve the quality of air.
Prevention of entry of dusts
In a dusty environment, install a silencer or a filter to the exhaust port and the breathing hole of pilot air to
prevent dusts from entering and causing an operation fault and fluid leakage.
