Caution

Selection of Pilot Valve

For the pilot valve oriﬁce diameter, ø5 mm or larger is

recommended.

When the pilot oriﬁce diameter is ø3 mm or larger and less

than ø5 mm, put “A” to the end of the product number for

made-to-order. The product may not operate correctly if the

pilot valve oriﬁce diameter is inadequate. (port size: 3/4, 1)

Depending on the pilot piping port size*1or length, the

valve may not operate correctly.

*1 The I.D. of the pilot piping must be larger than the pilot valve

oriﬁce diameter to use. The maximum pilot piping I.D. is 10 mm.

Working Principle

De-energized

The air enters from the IN side

goes through the supply oriﬁce of

the main valve and sub-valve to

fill the pressure action chamber.

The main valve and sub-valve are

closed by the pressure built in the

pressure action chamber.

Right after energized

When the pilot valve is ener-

gized, the armature opens,

and the air ﬁlling the pressure

action chamber is released to

the atmosphere through the

pilot valve.

Right after energized

When the pilot valve is ener-

gized, the armature opens,

and the air ﬁlling the pressure

action chamber qis released

to the atmosphere through

the pilot valve.

Energized (Main valve open)

Due to the release of air from

the pilot valve to atmosphere,

the pressure in the pressure

action chamber decreases

(force pushing the main valve

down < force pushing the

main valve up), opening the

main valve. Because of this,

the air ﬂows to the OUT side.

Energized (Sub-valve open)

Due to the release of air from the

pilot valve to atmosphere, the

pressure in the sub-valve

pressure action chamber q

decreases (force pushing the

sub-valve down < force pushing

the sub-valve up), opening the

sub-valve. Because of

this, the air filling the

pressure action cham-

ber wis released to

the atmosphere from

the exhaust port.

Energized (Main valve open)

Due to the release of air from the

pressure action chamber w, the

pressure in the pressure action

chamber wdecreases (force

pushing the main valve down <

force pushing the main valve up),

opening the main valve. Because of

this, the air ﬂows to the

OUT side of the pulse

valve.

De-energized

The air enters from the IN

side goes through the supply

oriﬁce of the main valve to ﬁll

the pressure action chamber.

The main valve is closed by

the pressure built in the pres-

sure action chamber.

Caution

Before starting the disassembly work, be sure

to shut off the power supply and pressure

supply, and then release the residual pressure.

1) Loosen the hexagon bolts and remove the bonnet,

O-ring, and main valve (sub-valve).

Disassembly

Assemble the main valve (sub-valve) to the body. The

main valve (sub-valve) has a required mounting direction.

Assemble the valve referring to Fig. 1.

If the valve is assembled in incorrect direction, it can cause a malfunction.

2) Mount the O-ring to the body groove. (See Fig. 2.)

After mounting of the O-ring, check if the O-ring is

ﬁtted properly in the groove. If it is out of the groove,

external leakage and/or operation failure may occur.

3) Assemble the bonnet to the body.

4) Tighten the hexagon bolts diagonally.

(See Table 1 for the tightening torque.)

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)

VXFC10: One board allows outputs at merely 10 output points max.

But the points can be increased to 20 and 30 output points by con-

necting cascades.

Interrupting an operation from an external switch is possible using in-

put signals.
