wCheck the applicable fluid check list
Use the tables on page 4.0-5 through 4.0-13
to check the compatibility of the applicable
fluid with the solenoid valve.
eConfirmation of working pressure differential VX
There are two possibilities for a pressure
differential. It is the highest pressure difference
allowable between the primary side and the
secondary side in an open and closed state. Or,
the minimum pressure differential is the lowest
required to hold the main valve fully open. Refer
to the following pages for each series as the
pressure differential varies with the orifice size,
power supply, pressure and fluid.

q Max. operating pressure differential
q Material
This pressure difference is the highest
pressure difference allowable to operate (a
difference between the pressures in the
primary slide and the secondary side) in an
open state and the closed state of valve. A
case of 0 kgf/cm2 in the secondary side
results in the highest operating pressure.
NBR: Nitrile rubber
FPM: Fluororubber
EPR: Ethylene-propylene rubber (=EPDM)
PTFE: Tetrafluoroethylene reain
Polyacetal (POM)
w Min. operating pressure differential
This pressure difference is the lowest pressure
difference (a difference between the pressures
in the primary side and secondary side)
required to hold the main valve fully open.
e Max. system presure
This pressure is the limit of pressure that
can be applied to pipe line (Line pressure)
[the pressure difference in a solenoid valve
must be maintained less than the highest
operating pressure difference.]
r Proof pressure.
This is the pressure that can be withstood
without deterioration of the performance when
valve returnes within the range of the operating
pressure.(A value under a specified condition.)
w Leakage amount
Vacuum leak amount 1atm·cc/sec: The
leakage amount is 1cc per second in
conversion to atmospheric pressure.
1atm·cc/sec=0.76 Torr·1/sec=760Lu/sec
e Oil preserve treatment
After assembly, a valve is put through a parts
washer to remove any oil used during
assembly.
r Symbol
The JIS symbol is (
): this designates
the valve to be normally closed. However, in
situations where the secondary pressure
exceeds the primary side pressure, the
resulting back pressure will cause back flow
through the valve.
VX
t Vaccuum pressure (Torr)
VNl
The absolute pressure is expressed.
0 Torr=Absolute pressure
0.760 Torr=Atmospheric pressure
(Gauge pressure 0 Kgf/cm2)
(1 torr=1.33 X 102 Pa)
VQ
Electrical Terms
q Volt-ampere(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
(Note) cosθ shows power factor.
w Surge voltage
The surge voltage is a high voltage generated
momentarily when cutting the power supply.
e Hum sound
The hum sound is a noise generated through
repeated adsorption and releasing on an
armature adsorption surface. For an AC
solenoid, no shading coil allows releasing by
spring reaction because of the existance of a
0 point (twice per frequency) of the suction
force.
Caution
Check Safty Instructions on p.0-33 and common precautions on
p.0-37 to 0-40.

Operation
<Valve opened> When the coil o is
energized, the armature assembly u is
attracted into the core of the core assembly y
and the pilot valve A opens.
Then the pressure in the pressure operated
chamber B falls to open the main valve C.

VX
VNl
OUT
When power is not supplied
Fluid from the IN side goes through the
supply orifice and fills the pressure action
chamber.
The main valve is kept closed by the force
pushing down the valve and the reaction
force of the return spring.
Right after power is supplied (Pilot valve opens)
When power is supplied to the coil, the
armature begins to be attracted, and the
pilot orifice opens.
The fluid filled in the pressure action chamber flows through the pilot orifice to the
OUT side.
IN
VQ
When power is being supplied (Main valve opens.)
Since the fluid is discharged from the pilot orifice,
the pressure in the pressure action chamber
decreases.
The force pushing down the valve weakens, and
the pressure pushing up the valve over-comes
the said force. Thus the main valve opens.
When the IN side has no pressure, or when the
pressure is very low,the reaction force of the lift
spring opens the main valve.

2 Port Solenoid Valve for Dust Collector
Series VXF
2 port solenoid valve for dust collector
Series VXF
In this L-shaped 2 port valve, the bag filter is cleaned by high
speed air jet and shock wave to materialize high speed
response and control of instantaneous large flow rate.
The supply port to the pressure
operation chamber is installed in
the body and the diaphragm free
from stress concentration has a
long life span.
Principles of operation (VXFA)
Fluid from the IN side goes through the
supply orifice and fills the pressure
action chamber. The main valve is kept
closed by the force pushing down the
valve and the reaction force of the
valve spring.
When power is supplied to the solenoid valve,
the armature begins to be retracted, and the
pilot orifice opens.
The fluid filled in the pressure action chamber
flows through the pilot orifice to the OUT side.
The main valve made of
polyacetal is free from sticking and
strong against produced shock
waves.

Since the bleeding lowers the pressure
inside the pressure operation chamber, the
valve pressing-down force becomes weaker
than the valve pressing-up force and the
valve is opened.
Controllers used exclusively for operation

Power voltage: 100V AC, 200V AC,
24V DC
Output points: 5 points, 10 points
LTwo-time hitting function
Two-time hitting can be set to improve the
sweeping effect by the bag filter. Two-time hitting
is available by turning ON the DIP SW (one-time by turning OFF).
LConnection of multiple circuit boards is possible
Number of output points can be increased (20/30 points) by connecting boards.
LWide ranging time setting

How to Select a Model (In case of use as a bag filter)
Model Selection
Since you can measure the deterrioration of VXF/VXFA properties due to the tube length from data B (response time/idle time) and data C (start-up
speed), refer to these data to set energization time. Use data A (flow rate characteristics) to calculate the flow rate for each loading time separately
in relation to the nozzle dia./qty., pressure, and tube although the data don’t correspond to the actual bag filter operation.
(In the data: “Without tube” and Tube length ø=VXF)
How to calculate
How to calculate
How to read the data
Provide the pressure from the air
resource to the air tank. Close the
stop valve, set the nozzle dia. and
qty., and then energize the solenoid
valve as well as the pilot valve of the
air operation valve in accordance
with the prescription.
(Change the tube length.)

The longer the tube length, the longer the response time and wasted time. If even longer
than the one in the diagram, the valve might not open due to the tube resistance.
Data C Start-up Speed
VXF2280, VXFA2280
How to view the diagram
The start-up speed stands for the degree of the nozzle inside
pressure rise per the unit of time. The greater it is, the stronger
the shock wave from the nozzle becomes. It also means that
the closing speed increases and consumption air can be used
effectively.
How to view the diagrams
Even if the energizing time is constant, a greater amount of air flows when the PA is at
0.7MPa than at 0.5MPa. Moreover, the greater the air tank capacity, the greater the amount
of airflow. Furthermore, the greater the nozzle's total cross sectional area, the greater the
amount of airflow. While the flow volume changes according to the length of the tube, be
aware that a wasted flow volume is involved during a return.

Instructions and p.0-37 to 0-40 for common precautions.
2 Port Solenoid Valve For
Dust Collector Series VXF
Silencer
Caution
q The silencer's response properties do not
change in the initial stage, but will
change due to the blockage after long
use. Replace it after about 500-thousandtime use, which is subject to the fluid
quality and energization time.
w When using a silencer, make a space
for silencer replacement.
Selection
Caution
q The response performance and start-up
speed deterriorate in case of air
operated style (VXFA) as compared
with a solenoid style (VXF) case. Refer
to the data for pilot piping.
w Be careful that, in DC case, idle time
and return time increase if the voltage
lowers. If a surge voltage suppressor is
installed, the return speed decreases.
Exclusive Controller Series
VXFC
Wiring
Warning
q The controller starts its output the
moment the power switch is turned ON.
Be aware that even if the power switch
is turned OFF, power is connected to
the terminal board.
Caution
q Make sure that the voltage of the power
to be input matches the voltage in the
controller's specifications. The voltage
of the power that has been input
becomes the voltage that is output to
the solenoid valves.
w Connect a ground that is rated Class-3
or greater to the power supply terminal
board.
e If the power is DC, pay attention to its
polarity. If the polarity is incorrect, it
could lead to a malfunction or damage.
r Operate at a voltage in the range of
–10% to +10% of the rated voltage.
Environment
Caution
q Operate under conditions that are free
of vibration and impacts.
w Operate in an ambient temperature
range between 0°C and 50°C.
e Operate in an ambient humidity range
between 35% to 85% (no condensation).
For further details, refer to the instruction
manual that is provided separately.
