Three position pneumatic actuators have two kinds of models 0! -45: -90; or
0" -90' -180' . In intake 2.the piston move to both ends after air inflow,it
through both ends design has auxiliary piston produces mechanical constraints to
realize the middle position It Gin use outside ends adjusting bolt easily odjust
intermediate position Angle directly Such as 20 : 30" 50' 75 ° or95: 120:
1 30° 1 50° 1 75° ,etc
