[3] Electromagnetic valve
Use table below to select your 5-port electromagnetic valve.
Air pressure to pump is 0.49MPa or below.
Caution
When a double-solenoid type electromagnetic valve is to be used, select a 2-position type. Use of a 3-position type
may deform the bellows, since the air on both sides is pressured or released simultaneously upon stopping the pump
with some 3-position type electromagnetic valve.
[4] Muffler
A muffler is installed on the exhaust port of the electromagnetic valve and quick exhaust valve.
FS-15, 30 : Select a muffler with an effective cross-section area of 35mm
2
or larger.
FS-60 : Select a muffler with an effective cross-section area of 60mm
2
or larger.
[5] Air piping
Select air pipes between the electromagnetic valve and pump or quick exhaust valve as specified in the following
table.
Air pressure to pump is 0.49MPa or below
Note: Both of right and left pipes length must be the same. Different length causes larger pulsation of liquid.
