Caution

・Continuous blow air can be changed to pulse air without electrical wiring by connecting the

pulse blow valve between air blow 2 port valve and nozzle of existing equipment.

・When an air gun and a pressure regulator are connected to OUT port, the back pressure of

the OUT port will be high. Therefore, the product cannot be used.

・When a vacuum ejector and a suction filter are connected to the OUT port, the back

pressure of the OUT port will be higher due to the clogging of the filter and silencer of the

vacuum ejector during operation. Therefore, the product cannot be used. In that case,

please use the external pilot type to avoid the influence of the back pressure.

・Keep using the plug and port with silencer.

・Direct manual override is operated by flat blade screwdriver. Insert the flat blade driver to

the groove until it contacts the bottom of the groove and turn the driver 90

degrees. Rotating direction does not matter. Do the same for release (push and rotate for

90 degrees).

・Tighten the piping using the correct torque shown below.

Caution

・The description of the sub plate and piping port do not match. Be careful with the piping

port.

・For external pilot type, pulse air is only generated while pilot air is supplied. The blow is

constantly stopped by the return spring when the pilot air is not supplied. Air may leak

from the main valve as this is metal seal type. (Refer to Fig.4)

・When the minimum operating pressure or more is supplied to the X port, air pulse is

generated even when IN port is pressure is less than the minimum operating pressure

(Refer to Fig.4).

・When the IN port pressure constantly exceeds the minimum operating pressure, the same

air can be connected to the IN port and X port (Refer to Fig.5).

・When the product is used in a condition where the OUT port back pressure varies, for

example, vacuum ejector and / or suction filter is connected to the OUT port, please

consider that the operation frequency will be changed.

・Keep using the plug and port with silencer.

・Direct manual override is operated by flat blade screwdriver. Insert the flat blade driver to

the groove until it contacts the bottom of the groove and turn the driver 90

degrees. Rotating direction does not matter. Do the same for release (push and rotate for

90 degrees).

・Tighten the piping using the correct torque shown below.

・Use an External pilot pressure higher than IN port pressure.

6. Frequency adjustment

Fig.6 Adjustment needle Fig.7 Adjustment needle Expansion

Caution

・ON time is shortened by rotating the ON time adjustment needle counterclockwise.

・OFF time is shortened by rotating the OFF time adjustment needle counterclockwise.

・Refer to the scale as a guideline for resetting. ON time ratio does not become 50% even

when setting the adjustment needle for ON and OFF at the same value.

・Small amount of leakage exists even when the needle is fully close. Do not use the

adjustment needle for the stopping of operation.

・When one needle is adjusted, the time for the opposite side will be slightly changed.

・Internal pilot: 1 to 5HZ and external pilot: 1 to 8Hz is reference.

・The charts on page 10 show the relation for the adjustment needle value and operation

frequency. However, there is approx. 2Hz of variation depending on individuality.

・Operating conditions affect the operating frequency.

Except for the adjustment needle, conditions below affect the operating frequency.

(1) Bore size and piping length (upstream and downstream)

(2) Supply pressure (the higher, the faster)

(3) Nozzle (The smaller of the exhaust port, the faster)

・Blow air may not become pulse air depending on the volume of the downstream.

Keep the product close to the nozzle as much as possible. (Guideline 1m)
