How to handle speed controller
(1) For an adjustment of the actual speed of this
product, release the nut Ⓐ and turn the knob Ⓑ .
Turn it clockwise to reduce the speed. Be careful,
as excessive turning will stop operation of this
product.
For double-acting type cylinders, adjust the
opening speed with the right knob and adjust the
closing speed with the left knob.
For single-acting type cylinders, only the speed
when operating air is discharged can be adjusted.
Adjust the speed only with the right knob. For
pressure-opening (7G), the closing speed can be
adjusted. For pressure-closing (7F), the opening
speed can be adjusted.
(2) After adjustment of the speed, fix the knob Ⓑ
and tighten the nut Ⓐ .
The speed controller is fully open when shipped. Please
adjust the speed before using it.

single acting type cylinder)
Limit switch box
This switch box is for remotely
displaying the open/close status of
the valve.
Positioner unit
(E/P Positioner and P/P Positioner)
This unit features a function that allows total control of the
valve opening, automatically and remotely.
Bypass valve
For manual operation, open the bypass
valve and equalize the pressure in the
left and right cylinder chambers.
Speed controller(standard)
This unit can adjust the opening
and closing speed of the valve.
Pilot type 5-port 2-position non-explosion-proof
solenoid valve unit (Single solenoid)
This unit opens and closes the valve following a remote
electrical signal that switches the airflow.
