3 Port Solenoid Valve for Fluid Control/Precautions 5
Be sure to read this before handling.
For detailed precautions on each series, refer to the main text.
1. Do not use the valves in an atmosphere ha-
ving corrosive gases, chemicals, salt water,
water, steam, or where there is direct contact
with any of these.
2. Do not use in explosive atmospheres.
3. Do not use in locations subject to vibration or
impact.
4. Do not use in locations where radiated heat
will be received from nearby heat sources.
5. Employ suitable protective measures in loca
-
tions where there is contact with water dro
-
plets, oil or welding spatter, etc.
Operating Environment
Warning
1. Filters and strainers
1. Be careful regarding clogging of filters and strainers.
2. Replace filter elements after one year of use, or earlier if the
pressure drop reaches 0.1 MPa.
3. Clean strainers when the pressure drop reaches 0.1 MPa.
2. Lubrication
When using with lubrication, never forget to lubricate contin-
uously.
3. Storage
In case of long term storage after use with heated water, tho-
roughly remove all moisture to prevent rust and deterioration of
rubber materials, etc.
4. Exhaust the drain from an air filter period-
ically.
Caution
1. Valves will reach high temperatures when
used with high temperature fluids. Use cau
-
tion, as there is a danger of being burned if
the valve is directly touched.
1 Removing the product
The valve will reach a high temperature when used with high
temperature fluids. Confirm that the valve temperature has
dropped sufficiently before performing work. If touched inadver
-
tently, there is a danger of being burned.
1. Shut off the fluid supply and release the fluid pressure in the
system.
2. Shut off the power supply.
3. Demount the product.
2. Low frequency operation
Switch valves at least once every 30 days to prevent malfunction.
Also, in order to use it under the optimum state, conduct a regular
inspection once every six months.
Warning
1. This solenoid valve can be operated without
lubrication.
If a lubricant is used in the system, use turbine oil Class 1, ISO
VG32 (with no additive). But do not lubricate a valve with EPDM
seal.
Refer to the table of brand name of lubricants compliant with
Class 1 turbine oil (with no additive), ISO VG32.
