Determination of flow-rate characteristics
JIS B 8390: 2000 : Pneumatic fluid power—Components using compressible fluids—
How to test flow-rate characteristics
(2) Definition of flow characteristics
Flow rate characteristics are indicated as a result of a comparison between sonic conductance C and critical pressure ratio b.
Sonic conductance C : Value which divides the passing mass flow rate of an equipment in a choked flow condition by the
product of the absolute upstream pressure and the density in the standard condition.
Critical pressure ratio b : Checked flow will occur when the pressure ratio (downstream pressure/upstream pressure)
is at or smaller than this value.
Choked flow
: It is the flow in which the upstream pressure is higher than the downstream pressure and where
sonic speed is reached in a certain part of the equipment.
Gaseous mass flow rate is in proportion to the upstream pressure and not dependent on the
downstream pressure.
Subsonic flow
: Flow when the pressure ratio is greater than the critical pressure ratio.
Standard condition
: Air in a temperature state of 20°C, absolute pressure 0.1 MPa (= 100 kPa = 1 bar), relative humidity
65%.
It is stipulated by adding the abbreviation (ANR) after the unit depicting air volume.

Obtain the air flow rate when P1 = 0.4 [MPa], P 2 = 0.3 [MPa], t = 20 [°C] for a solenoid valve where C = 2 [dm3/(s·bar)] and b = 0.3.

(4) Test method
Pipe the text equipment to the text circuit shown in Fig. (1). Keep the upstream pressure at a certain constant level above
0.3MPa. First measure the maximum flow rate in saturation. Then, measure the flow rate, upstream pressure and downstream
pressure each at 80%, 60%, 40% and 20% points of the flow rate. Calculate the sonic conductance C from the maximum flow
rate. Also substitute other data for variables in the formula for subsonic flow and obtain the critical pressure rate b by averaging
the critical pressure rates at those points.

(4) Test method
Pipe the text equipment to the text circuit shown in Fig. (2). Fill the air tank with compressed air and keep the pressure at a
constant level above 0.6MPa (0.5MPa). Then discharge the air until the pressure in the tank drops to 0.25MPa (0.2MPa).
Measure the time required to dischargue the air and the residual pressure in the air tank after leaving it until the pressure
becomes stable in order to calculate the effective sectional area S by the following formula. Select the capacity of the air tank
according to the effective sectional area of the text equipment. In the case of JIS B 8373, 8374, 8375, 8379, 8381, the pressure

2.3 Flow coefficient Cv factor
The United States Standard ANSI/(NFPA)T3.21.3:1990: Pneumatic fluid power—Flow rating test procedure
and reporting method for fixed orifice components
defines the flow coefficient Cv factor by the following formula which is based on testing conducted with a test circuit analogo us to
ISO 6358.

∆P : Pressure drop between the static pressure tapping ports [bar]

P2 : Pressure of the downstream tapping port [bar gauge]:P2 = P1 – ∆P
Q : Flow rate [dm3/s standard condition]
Pa : Atmospheric pressure [bar absolute]
T1 : Upstream absolute temperature [K]
Test conditions are < P1 + Pa = 6.5 ± 0.2 bar absolute, T1 = 297 ± 5K, 0.07 bar ≤ ∆P ≤ 0.14 bar.
This is the same concept as effective area A which ISO6358 stipulates as being applicable only when the pressure drop is small
in relation to the upstream pressure so that the compression of air is negligible.

Cv factor (Reference values): It is the value representing the flow rate of clean water in US gal/min which runs through the valve
at 60°F, when the pressure difference is 1 lbf/in2 (psi).

Example 1)
Obtain the pressure difference when 15 [l/min] of water runs through the solenoid valve with an Av = 45 x 10–6 [m2].
Since Q0 = 15/45 = 0.33 [l/min], according to the Graph (2), if reading ∆P when Q0 is 0.33, it will be 0.031 [MPa].
Example 2)
Obtain the flow rate of saturated aqueous vapour when P1 = 0.8 [MPa], ∆P = 0.008 [MPa] with a solenoid valve with an Av =1.5 x
10–6 [m2].
According to the Graph (2), if reading Q0 when P1 is 0.8 and ∆P is 0.008, it is 0.7 [kg/h]. Hence, the flow rate Q = 0.7 x 1.5 = 1.05

(4) Test method
By attaching the equipment for testing with the test circuit shown in Fig. (3) and running water at 5 to 40°C, measure the flow rate
with a pressure difference of 0.075 MPa. However, the pressure difference needs to be set with a large enough difference so that
the Reynolds number does not go below a range of 4 x 104.

Glossary of Terms
Pressure Terminology
1. Maximum operating pressure differential
The maximum pressure differential (the difference between
the inlet and outlet pressure) which is allowed for operation,
with the valve closed or open. When the downstream pressure is 0 MPa, this becomes the maximum operating pressure.
2. Minimum operating pressure differential
The minimum pressure differential (differential between the
inlet pressure and the outlet pressure) required to keep the
main valve fully opened.
3. Maximum system pressure
The maximum pressure that can be applied inside the pipelines (line pressure).
(The pressure differential of the solenoid valve unit must be
less than the maximum operating pressure differential.)
4. Withstand pressure
The pressure which must be withstood without a drop in
performance after returning to the operating pressure range.
(value under the prescribed conditions)
Electrical Terminology
1. Apparent power (VA)
Volt-ampere is the product of voltage (V) and current (A). Power dissipation (W): For AC , W = V.A cosθ. For DC, W = V.A.
(Note) cosθ shows power factor. cosθ = 0.6
2. Surge voltage
A high voltage which is momentarily generated in the shut-off
unit by shutting off the power.
3. Degree of protection
A degree defined in the “JIS C 0920: Waterproof test of electric machinery/appliance and the degree of protection against
the intrusion of solid foreign objects”.
IP65: Dust-tight, Low jetproof type
“Low jetproof type” means that no water intrudes inside the
equipment that could hinder it from operating normally by
means of discharging water for 3 minutes in the prescribed
manner. Take appropriate protection measures, since a device is not usable in an environment where a water drop is
splashed.

3 Port Solenoid Valve for Fluid Control/Precautions 1
Be sure to read this before handling.
For detailed precautions on each series, refer to the main text.
Selection
Design
Warning
Warning
1. Cannot be used as an emergency shutoff valve, etc.
The valves presented in this catalogue are not designed for safety applications such as an emergency shutoff valve. If the valves are used in this type of system, other reliable safety assurance measures should also be adopted.
2. Extended periods of continuous energisation
The solenoid coil will generate heat when continuously energised. Avoid using in a tightly shut container. Install it in a wellventilated area. Furthermore, do not touch it while it is being
energised or right after it is energised.
3. This solenoid valve cannot be used for explosion proof applications.
4. Maintenance space
The installation should allow sufficient space for maintenance
activities (removal of valve, etc.).
5. Liquid rings
In cases with a flowing liquid, provide a bypass valve in the
system to prevent the liquid from entering the liquid seal circuit.
6. Actuator drive
When an actuator, such as a cylinder, is to be driven using a
valve, take appropriate measures to prevent potential danger
caused by actuator operation.
7. Pressure (including vacuum) holding
It is not usable for an application such as holding the pressure
(including vacuum) inside of a pressure vessel because air leakage is entailed in a valve.
8. When the conduit type is used as equivalent
to an IP65 enclosure, install a wiring conduit,
etc.
9. When an impact, such as water hammer, etc.,
caused by the rapid pressure fluctuation is
applied, the solenoid valve may be damaged.
Please pay attention to this.
Selection
Warning
1. Confirm the specifications.
Give careful consideration to the operating conditions such as
the application, fluid and environment, and use within the operating ranges specified in this catalogue.
2. Fluid
1) Type of fluid
Before using a fluid, confirm whether it is compatible with the
materials from each model by referring to the fluids listed in
this catalogue. Use a fluid with a kinematic viscosity of 50
mm2/s or less. If there is something you do not know, please
contact SMC.
2) Inflammable oil, Gas,
Confirm the specification for leakage in the interior and/or exterior area.
Back page 2
3) Corrosive gas
Cannot be used since it will lead to cracks by stress corrosion
or result in other incidents.
4) Use an oil-free specification when oil particles must not enter
the fluid passage.
5) Applicable fluid on the list may not be used depending on the
operating condition. Just because the compatibility list shows
the general case, still give adequate confirmation when selecting a model.
3. Fluid quality
The use of a fluid which contains foreign matter can cause problems such as malfunction and seal failure by promoting wear of
the valve seat and armature, and by sticking to the sliding parts
of the armature, etc. Install a suitable filter (strainer) immediately
upstream from the valve. As a general rule, use 80 to 100 mesh.
When used to supply water to boilers, substances such as
calcium and magnesium which generate hard scale and sludge
are included. Since this scale and sludge can cause the valve to
malfunction, install water softening equipment, and a filter
(strainer) directly upstream from the valve to remove these
substances.
4. Air quality
1) Use clean air.
Do not use compressed air which includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases,
etc., as it can cause damage or malfunction.
2) Install air filters.
Install air filters close to the valves on their upstream side. A
filtration degree of 5µm or less should be selected.
3) Install an air dryer or after cooler, etc.
Compressed air that includes excessive drainage may cause
malfunction of valves and other pneumatic equipment. To
prevent this, install an air dryer or after cooler, etc.
4) If excessive carbon powder is generated, eliminate it by installing mist separators on the upstream side of the valves.
If excessive carbon powder is generated by the compressor,
it may adhere to the inside of the valves and cause a malfunction.
Refer to SMC’s Best Pneumatics catalogue for further details on
compressed air quality.
5. Ambient environment
Use within the operable ambient temperature range. Confirm
the compatibility between the product’s composition materials
and the ambient atmosphere. Be sure that the fluid used does
not touch the external surface of the product.
6. Countermeasures against static electricity
Take measures to prevent static electricity since some fluids can
cause static electricity.
7. For the low particle generation specification,
please contact SMC.

Caution
Caution
1. Leakage voltage
Particularly when using a resistor in parallel with a switching
element and using a C-R element (surge voltage suppressor) to
protect the switching element, take note that leakage current
will flow through the resistor, C-R element, etc., creating a possible danger that the valve may not turn off.

1. Preparation before piping
Before piping is connected, it should be thoroughly blown out
with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe.
2. Wrapping of pipe tape
When connecting pipes, fittings, etc., be sure that chips from the
pipe threads and sealing material do not enter the valve.
Furthermore, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.

2. Low temperature operation
1. The valve can be used in an ambient temperature of between
–10 to –20°C, however take measures to prevent freezing or
solidification of impurities, etc.
2. When using valves for water application in cold climates, take
appropriate countermeasures to prevent the water from freezing in tubing after cutting the water supply from the pump,
by draining the water, etc. When heating by steam, be careful not to expose the coil portion to steam. Installation of a
dryer or heat retaining of the body is recommended to prevent a freezing condition in which the dew point temperature
is high and the ambient temperature is low, and the high flow
runs.

3. Avoid connecting ground lines to piping, as
this may cause electric corrosion of the
system.
4. Always tighten threads with the proper tightening torque.
When attaching fittings to valves, tighten with the proper tightening torque shown below.
Tightening Torque for Piping
Mounting
Warning
1. If air leakage increases or equipment does
not operate properly, stop operation.
After mounting is completed, confirm that it has been done correctly by performing a suitable function test.
2. Do not apply external force to the coil section.
When tightening is performed, apply a wrench or other tool to
the outside of the piping connection parts.
3. Be sure not to position the coil downwards.
When mounting a valve with its coil positioned downwards, foreign objects in the fluid will adhere to the iron core leading to a
malfunction.
4. Do not warm the coil assembly with a heat insulator, etc.
Use tape, heaters, etc., for freeze prevention on the piping and
body only. They can cause the coil to burn out.

manual to avoid mistakes regarding the supply port, etc.
6. Steam generated in a boiler contains a large
amount of drainage.
Be sure to operate it with a drain trap installed.
7. In applications such as vacuum and non-leak
specifications, use caution specifically
against the contamination of foreign matters
or airtightness of the fittings.
5. Secure with brackets, except in the case of
steel piping and copper fittings.
6. Avoid sources of vibration, or adjust the arm
from the body to the minimum length so that
resonance will not occur.
7. Painting and coating
