Working principle (VXFA)
In this L-shaped 2 port valve, the bag filter is cleaned by high speed air jet and shock
Fluid from the IN side goes through the
wave to materialize high speed response and control of instantaneous large flow rate. De-energized

chamber. The main valve is kept closed
by the force pushing down the valve and
the reaction force of the valve spring.
The supply port to the pressure
action chamber is installed in the
body and the diaphragm free from
stress concentration has a long life
span.

Armature
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.

Since the bleeding lowers the pressure inside
the pressure action chamber, the valve pressing-down force becomes weaker than the valve
pressing-up force and the valve is opened.

Model Selection (In the case of using as a bag filter)
Model selection
The deterrioration of VXF/VXFA properties due to the tube length from data B (response time/idle time) and data C (start-up speed), can be measured.
Refer to this 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. The data does not correspond to the actual bag filter operation. (In the data: “Without tube” and Tube length ø = VXF)
How to calculate
How to read the data
Pilot valve
(I.D. ø6, ø10)
How to calculate
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.)

Energization time T (ms)
How to read the graph
Even if the energizing time is constant, a greater amount of air flows when the PA
is at 0.7 MPa than at 0.5 MPa. 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.
How to read the graph
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 of air can be used effectively.
Start-up speed θ = PM x 0.9

Interrupt operation Function
A two-time hitting function is adopted to improve the bag filter dusting
efficiency. Turn ON the dip switch for two-time hitting (OFF for one-time
hitting).
(Effective up to the number of setting channels)
Interrupting an operation from an external switch is possible using
input signals.

VXF
Specific Product Precaution
Series
Be sure to read before handling. Refer to front matters 42 and 43 for Safety Instructions,
and pages 17 to 19 for 2 Port Solenoid Valves for Fluid Control Precautions.
2 Port Solenoid Valve for
Dust Collector: Series VXF
Silencer
Caution
1. 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 using about 500,000 times. This number is subject
to change based on fluid quality and energization time.
2. When using a silencer, make space for silencer replacement.
Selection
Caution
1. The response performance and start-up speed deterriorate in
case of air operated type (VXFA) as compared with a solenoid
type (VXF) case. Refer to the data for pilot piping.
2. Note that for DC units, idle time and return time increase if the
voltage is lowered. If a surge voltage suppressor is installed,
the return speed decreases.
Dedicated Controller for
Operation: Series VXFC
Wiring
Warning
1. 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
1. 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.
2. Connect a ground that is rated Class 3 or greater to the power
supply terminal board.
3. If the power source is DC, use caution to its polarity. If the polarity is incorrect, it may result in a malfunction or damage.
4. Refer to the separate operation manual for further details.
Environment
Caution
1. Operate under conditions that are free of vibration and impact.
2. Operate in an ambient temperature range between 0°C and
50°C.
3. Operate in an ambient humidity range between 45% to 85%
(with no condensation). For further details, refer to the instruction manual in which it is explained separately.
