Fabco-Air Air-Oil Tanks


Air-Oil tanks provide a cost effective alternative to hydraulic systems when precise air cylinder motion is required.
Example #1: Single Air-Oil Tank used for 2-speed work stroke with shock control.
The sequence is as follows:
  1. Rapid "extend" stroke to approach the work.
  2. Automatic switch to controlled rate when resistance is met and pressure builds up to the point where a Fabco-Air RV "Sequence Valve" actuates the 2-way shut-off valve forcing fluidflow through the speed controlling needle valve. (See RV valve info)
  3. Fluid catches the cylinder motion, thus controlling the shock that could otherwise occur.
  4. Automatic return to rapid rate on the "Cylinder Retract" stroke. (See more circuits in catalog # CV9)
Example #2: Double Air-Oil Tanks are needed when control is required in two directions.
Double tanks, used in conjunction with two flow control valves, enables hydraulic control with one speed in each direction.
