††H/60††H
An IP65 dust-proof/splash-proof specification can be achieved by applying the pressure specified below from the
air supply port provided on the side face of the base.
Service pressure Pressure in a range of 0.5 to 0.6 MPa immediately before the bellows inflates
Pipe size Outer diameter
‡6 x Inner diameter ‡4
Fluid used
Clean, dry air free from compressor oil, etc. The air filtration rating shall be 10
Pm or less,
dew point of dry air in atmosphere shall be -20 qC or less.
z Flow rate adjustment method
The customer should provide a relief valve. Fully close the speed controller supplied with the actuator, set
the pressure to 0.3 MPa or more but not exceeding 0.6 MPa, and then adjust the flow rate using the speed
controller supplied with the actuator.
Supplying too much air will inflate the bellows.
Adjust the speed controller by following the procedure below.
<Increase the flow rate>
Turn the needle of the speed controller counterclockwise from the fully closed position to increase the flow
rate.
Supplying too much air will inflate the bellows, so adjust the needle until immediately before the bellows
inflates.
After the adjustment, be sure to tighten the lock nut to maintain the flow rate.
