Conversion of the discharge volume
Calculate the discharge volume by reading the tank
pressure after the valve starts the operation.
Conversion equation
V0 = (P1 x V1 − P2 x V1)/P0
V0: Discharge volume L
P1: Tank initial pressure MPa (Absolute pressure)
V1: Tank capacity L
P2: Tank pressure after release MPa (Absolute pressure)
Test circuit
Note 1) If the regulator or the restrictor is installed right before the IN side of the valve,
the valve may oscillate when it is turned off. Keep the regulator or the restrictor
away from the valve for at least 1 m or change restriction.
Note 2) The dust collector valve is a large flow control valve in which air is discharged
with high speed to clean the bag filter with impact wave. Tank capacity should
be sufficient to secure impact wave and discharge flow rate. If the air tank
capacity is insufficient, response delay of valve, malfunctions or oscillation
may occur.

The fluid enters from the IN
goes through the supply orifice
of the diaphragm to fill the
pressure action chamber. Main
valve is closed by the pressure
in the pressure action chamber
and the reaction force of the
spring.

When the solenoid valve is
energized, the armature opens
and the fluid filling the pressure
action chamber q of the pilot
diaphragm valve is released to
the atmosphere.

When the solenoid valve is
energized, the armature opens
and the fluid filling the pressure
action chamber is released to
the atmosphere.
Energized (Pilot diaphragm valve open)
q
Energized (Main valve open)
The pressure in the pressure
action chamber decreases by
releasing the fluid to the
atmosphere. Because the force
which pushes down the main
valve is reduced by the release
of the fluid, the force that pushes
up the main valve overcomes
the push down force and opens
the main valve.

The pressure in the pressure action
chamber q of the pilot diaphragm

fluid to the atmosphere. Because
the force which pushes down the

Warning
2. Extended periods of continuous energization
The solenoid coil will generate heat when continuously energized.
Avoid using in a tightly shut container. Install it in a well-ventilated area.
Furthermore, do not touch it while it is being energized or right after it is
energized.
3. When the conduit type is used as equivalent to an IP65
enclosure, install a wiring conduit etc.
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 energizing time.
2. When using a silencer, make space for silencer replacement.
Selection
Warning
1. Air quality
1. Use clean air.
Do not use compressed air that contains chemicals, synthetic oils
including organic solvents, salt or corrosive gases, etc., as it can
cause damage or malfunction.
2. Install an air filter.
Install an air filter close to the valve on the upstream side. A
filtration degree of 5 µm or less should be selected.
3. Install an aftercooler or air dryer, etc.
Compressed air that contains excessive drainage may cause
malfunction of valves and other pneumatic equipment. To prevent
this, install an aftercooler or air dryer, etc.
4. If excessive carbon powder is generated, eliminate it by
installing a mist separator on the upstream side of 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 the Best Pneumatics No. 5 for further details on
compressed air quality.
2. Ambient environment
Use within the allowable ambient temperature range. Check the
compatibility between the product’ s composition materials and the
ambient atmosphere. Be certain that the fluid used does not touch
the external surface of the product.
3. Countermeasures against static electricity
Take measures to prevent static electricity since some fluids can
cause static electricity.
4. Low temperature operation
1. The valve can be used in an ambient temperature of between –4 to
14° F (–20 to –10° 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 warming by a heater etc., be careful not to
expose the coil portion to a heater.
Installation of a dryer, 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.
5. Fluid properties
Use a general compressed air with a filter of 5 µm or less mounted
on the inlet of the piping. (Excluding dry air)
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.

Mounting
Caution
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. Mount a valve with its coil position upward, not
downward.
When mounting a valve with its coil position downward, foreign
objects in the fluid will adhere to the iron core leading to a
malfunction. Especially for strict leakage control, such as with
vacuum applications and non-leak specifications, the coil must be
positioned upward.
3. Always tighten threads with the proper tightening torque.
When attaching fittings to valves, tighten with the proper
tightening torque shown below.

Wiring
Piping
Warning
1. During use, deterioration of the tube or damage to the
fittings could cause tubes to come loose from their
fittings and thrash about.
To prevent uncontrolled tube movement, install protective covers or
fasten tubes securely in place.
2. For piping the tube, fix the product securely using the
mounting holes so that the product is not in the air.
Caution
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.
Install piping so that it does not apply pulling, pressing, bending or
other forces on the valve body.
2. Avoid connecting ground lines to piping, as this may
cause electric corrosion of the system.
Caution
1. As a rule, use electrical wire with a cross sectional area
of 0.5 to 1.25 mm2 for wiring.
Furthermore, do not allow excessive force to be
applied to the lines.
2. Use electrical circuits which do not generate chattering
in their contacts.
3. Use voltage which is within ±10% of the rated voltage. In
cases with a DC power supply where importance is
placed on responsiveness, stay within ±5% of the rated
value. The voltage drop is the value in the lead wire
section connecting the coil.
4. When a surge from the solenoid affects the electrical
circuitry, install a surge voltage suppressor etc. in
parallel with the solenoid. Or, adopt an option that
comes with the surge voltage protection circuit.
(However, a surge voltage occurs even if the surge
voltage protection circuit is used. For details, please
consult with SMC.)
