Valve Operation
1. Actuator drive
Take appropriate measures to prevent potential danger caused by
actuator operation when an actuator is to be driven using a solenoid
valve.
2. Intermediate stopping
Accurate stop of the piston in a predetermined position is not possible
due to the compressibility of air when a 3-positon closed center valve
is used to stop a cylinder at a intermediate position.
Furthermore, it may not be possible to hold a stopped position for an
extended length of time since valves and cylinders are not guaranteed
for zero air leakage.
3. Effect of back pressure
You need to be careful when using valves on a manifold because
actuator malfunction due to back pressure may occur.
Your special attention should be taken when using a 3-postion
exhaust center valve or driving a single acting cylinder.
Implement countermeasures such as the use of an individual exhaust
spacer assembly when there is a danger of back pressure.
4. Since valves are subjected to air leakage, they cannot be used
for applications such as holding pressure.
5. Can't be used as an emergency shutoff valve, etc.
6. Release of residual pressure
Provide residual pressure lease function for maintenance purposes.
Special consideration should be given to the release of residual
pressure between the valve and cylinder in case of a 3-position
closed center type valve.
Installation
1. Momentary energization
If a double solenoid valve will be operated with momentary
energization, it should be energized for at least 0.1 second.
2. Leakage voltage
1) Residual leakage voltage of DC coil must be or less than 2%
1. Conrm the Specications.
Don’t operate at pressures or temperatures beyond the range of
specications because this can cause damage or malfunction.
PRECAUTION: Valve
Be sure to read before handling.
Air Supply
1. Use clean air
Use clean air which doesn't contain chemicals, synthetic oils
containing organic solvents, salts or corrosive gases etc., because
this can cause damage or malfunction.
1. Filteration to 5µm is recommended.
2. Large quantity of drainage may cause incorrect operation of pneu-
matic products as well as environmental contamination. Please
control drainage. You can use the lter with auto drainage in case
of difculty.
3. Please install a mist separator when there is a large amount of
carbon power from the compressor.
Warning Warning
Caution
Environment
1. Keep away from corrosive gas, chemical solutions, sea water, rain
and steam.
2. Avoid using in an explosive atmosphere.
3. Don't use in locations subject to vibration or impact.
4. Avoid direct sunlight.
5. Shield radiated heat generated by nearby heat sources.
6. Use a protective cover when installed in a place where a drop of
water or oil will splash momentarily.
7. Please install a silencer on the exhaust port in a dusty place.
Warning
Caution
Caution
Lubrication
1. No further lubrication is required because valves are prelubricated.
2. Please use turbine oil ( ISO VG32 or equivalent to ) if lubricant is
required. Once lubrication is applied, it must be continued because
the original lubricant may be eliminated.
