Seat Adjuster cannot be unscrewed totally; there is a screw stopper to prevent that.
The Seat Adjuster is adjusted and set prior to shipment for balanced pressure point of output pressure.
There should be no need for adjustment.
Seat adjuster is always used for double acting configurations.
Should there be a need to change the balanced pressure point, use the seat adjuster.
- Should the sensitivity be poor due to actuator type of load condition, turn the Seat Adjuster Screw clockwise.
(The stopper screw is set to avoid the removal of the seat adjuster screw, do not loosen the stopper screw.)

That means is it used for adjusting sensitivity?
