Schematic diagram of fast forward and fast backward of pneumatic system

Neither the differential control circuit nor the bypass control circuit can be used, and only one reversing valve is used. These conditions are quite harsh.

Answer now? Cylinder fast feed-feed-feed-quick return. See the following figure for the control schematic diagram:

Then, gas-liquid damping cylinders are connected in series: cylinder fast forward, working, working and fast return. But the cylinder is much more complicated than the pneumatic mentioned above. I can give you the control schematic diagram if necessary.
