12. Flow rate characteristics
The flow rate characteristics may differ depending on the individual unit, operating, and piping
conditions.
Fully conduct a check under the actual operating conditions, and then select a model that has a
sufficient margin with respect to the required flow rate.
13. PWM control
The product conducts PWM control to suppress the hysteresis.
Use the product under the frequency condition of 450 Hz (size 10) or 350 Hz (size 20).
14. The product is adjusted to individual specifications at the time of shipment from the factory.
Do not operate the adjustment screw by loosening the nut located at the upper part of the product.
Operating the adjustment screw may lead to a malfunction.
Do not perform disassembly or removal of parts as doing so will cause a failure.
15. The flow rate is controlled through balancing of the valve element.
Avoid external impact and vibration as they will change the flow rate.
16. Port size of size 20 (water)
If size 20 (orifice diameter of ø2) is used for water, make the inner diameter of the secondary side pipe
ø6.5 mm or larger.
17. Nozzle diameter
When connecting a nozzle to the end of the pipe, the nozzle size diameter should be equal to or larger
than the orifice diameter as a guide.
If the nozzle diameter is smaller than the orifice diameter, stable flow rate control may be disabled.
Sufficiently check the controllability under the actual operating conditions.
2. Operating Environment
Warning
Do not use this product under any of the following conditions. It may lead to a malfunction or
failure.
1. Location where the product may be exposed to an atmosphere containing steam, corrosive
fluid (chemicals), seawater, or water.
Even on a product with a protection classification (IP65, IP67), take appropriate protection measures if
it is used in an environment where water is splashed to it for a long time. Water may enter from minute
gaps on the outer surface of the product and it may cause coil burnout or short circuit with solenoid
valves. Check that liquid or splatter does not splash on the product from peripheral equipment when
installing this product near equipment that uses a large amount of water or oil, such as machining tool
and machining equipment.
2. Location with explosive atmospheres
3. Location where vibration or impact is generated
4. Location where the product is exposed to heat sources or exposed to radiant heat
5. Location where freezing occurs inside the piping
[When fluid is liquid]
Provide freezing countermeasures for the liquid when used in a cold region or in winter. When the fluid
freezes, provide countermeasures such as discharging water inside the piping when the equipment is
stopped or installing a heater or thermal insulator for the piping. When heating the solenoid valve,
avoid heating the coil area to prevent deterioration of heat dissipation.
[When fluid is air]
When a large flow rate is applied, drainage may be generated due to adiabatic expansion and it may
freeze.
Regularly discharge the drainage or remove the drainage using an air dryer.
Caution
1. Use of the product outdoors
1) Although the weather resistance of the product has been improved, its outdoor use is not
guaranteed.
2) The product does not guarantee anti-corrosion performance (being free from rust generation and
discoloration).

3. Precautions for Fluid
Warning
1. Fluid selection
Compatibility between the components and fluids should be checked in the application before use.
Do not use the fluids described below.
1) Fluids harmful to the human body
2) Burnable, combustible fluids
3) Corrosive gas
4) Sea water, saline solution
2. Take measures to prevent static electricity since some fluids can cause static electricity.
3. Fluid temperature
Operate the product within the specified operating fluid temperature.
4. Install a filter (strainer) to use clean fluids.
1) The use of a fluid that contains foreign matter can cause issues such as malfunction and seal
failure due to wear of the valve seat armature as well as adhesion of foreign matter on the sliding
parts of the armature. Install a filter (strainer) on the upstream side of the valve to remove foreign
matter.
Air: 5 μm or less, water: 100 mesh or more
2) Replace or clean the filter or strainer when the pressure drop reaches 0.1 MPa to prevent them
from getting clogged.
5. If the product is used with water or warm water, a malfunction or leakage may occur due to
dezincification symptom, erosion, corrosion, or the like.
Stainless steel body type with improved anti-corrosion performance is also available.
Please select the products depending on what best suits the application.
4. Fluid quality
Warning
1. Air supply
1) Do not use compressed air which includes chemicals, synthetic oils containing organic solvents,
salt, corrosive gases, etc., as this can cause damage or malfunction.
2) Compressed air that contains excessive drainage may cause malfunction of valves and other
pneumatic equipment. Install an aftercooler or air dryer on the inlet side of the valve as a
countermeasure against the drainage.
3) If excessive carbon dust is generated by the compressor, it may adhere to the inside of the valve
and cause malfunction. Install a mist separator on the inlet side of the valve as a countermeasure
for removing the carbon powder.
4) For detailed information regarding the quality of the compressed air, refer to SMC's Compressed Air
Cleaning System.
5) When air with an ultra-low dew point of −70°C or lower, the inside of the valve may wear, reducing
the product life.
2. Water
1) Operation failure due to rust generated or chloride flowing in the piping may result in the breakage
of the product. Provide an appropriate protective measure against the scattering of fluids or
components that may be caused when the product is broken.
2) Water contains substances that generate scale and sludge such as calcium and magnesium. The
product may malfunction when they adhere to the internal surface of the valve. Therefore, install
water-softening equipment and a filter (strainer) on the inlet side of the valve to remove those
substances.
3) The water pressure of the tap water is 0.4 MPa or less, in general. However, the pressure may
increase to 1.0 MPa in a high-rise building. Therefore, pay attention to the maximum operating
pressure differential.

5. Mounting
Warning
1. When mounting the products, allow enough space to provide access for maintenance.
2. Avoid sources of vibration or adjust the arm from the body to the minimum length to prevent
the generation of resonance.
3. Do not install the product near a heat source or a location exposed to radiant heat.
4. Do not apply external force to the coil section.
When mounting the product, apply a spanner on the outside of the piping connection while paying
attention not to come into contact with the coil.
5. Do not warm the coil area with a heat insulator, etc.
When the product is heated as a countermeasure against freezing, the heating parts should be limited
to the piping and body only. Do not heat the coil. Heating the coil may burn it out.
6. If leakage increases or the equipment does not operate properly, stop the operation.
After mounting or during maintenance, check that the product is correctly mounted with appropriate
functional and leakage inspections by supplying compressed air and power supplies. Do not use the
product if the equipment does not operate correctly.
7. Do not touch the valves with bare hands during or right after energization.
Valves will reach high temperatures during energization. Do not touch the valve carelessly as it may
cause burns.
8. Mounting of base piping type
When installing the product on a base, check the fitting condition of the O-ring on the interface
surface, and then securely tighten the screw to the tightening torque shown in the table below.
Appropriate tightening torque (Nm)
JSP10(Base ported type) 0.9±10%
JSP20(Base ported type) 1.4±10%
Mounting direction of base piping type
For mounting, refer to the full view.
9. Orientation
As a preventive measure against accumulation of foreign matter and others, we recommend that the
coil be installed in the upward direction.
Caution
1. Painting and coating
Warnings or specifications printed or affixed to the product should not be erased, removed, or covered
up.
6. Bracket mounting
Caution
1. JSP10 series Body material: SUS, Brass (Port size 1/8)
