Safety Rules for Use
■
Impurities contained in air may cause malfunctions or troubles of solenoid valves. Remove drain and dust
from the supply air.
■
Apply flushing to both supplying and cylinder sides when piping. Place a filter (filtering accuracy: 5
μ
m or
less) close to a solenoid valve.
■
A large amount of drain, excessive lubrication and super dry air may cause malfunctions or troubles. Pay
special attention to air quality.
1. Air Quality
■
Operate solenoid valves under the following environment.
・
Within Operating Temp. Range
・
Avoid dew condensation by temperature change
・
No water / oil drops and dust
・
No corrosive gas
2. Operating Environment
■
When a solenoid valve is operated by a programmable controller, leakage current in output side shall be
less than 1mA. There is a risk that the leakage current of the output can cause malfunctions.
3. Leakage Current
■
When a solenoid valve is operated under a
vibrating condition, install it so that a spool valve
is at a right angle to the vibrating direction.
(Operate the valve under a vibration of less than
49m/s
2
)

■
No lubrication is necessary.
■
When a system needs to be lubricated, use Turbine Oil Class 1 (ISO VG 32) / free of additives. If the
lubrication is stopped supplying to the system in the middle of operation, malfunctions may be caused
due to the loss of the initial lubricant on valves. Keep providing lubricant.
5. Lubrication
①
Loosen the one fixing screw with a Philips
screwdriver and take it out completely from
the valve unit. (One screw clamping function)
