Type AA Actuator

The AA is a powerful diaphragm radial positioner. The force reaches 1125 inch-lb-degrees. Supply pressure range 10-60PSI. The AA acctuator is easily mounted and has a compact foot print.

The AA acctuator is made in 3 different versions. AA-1 is the basic modle shown in the picture. The AB-1 has an additional stop cylinder. The BA-1 modle is equiped with a second smaller vernier acctuator. The verneer acctuator allows fine adjustments when connected to an e.g. H-4 control valve.

Three Position Cylinder

The three position cylinder has a stellar reputation for shifting transmissions and positioning hydraulic valves. The body is made from die-cast corrosion-resistant aluminum. The lightweight cylinder can be mounted direct to the gear box, using the integrated clevis. PSI can provide a mounting braket for easy install.
