I agree with what Mark has said if one input port is distributing air to 2 output ports with both output ports sending air to a cylinder (one for push and one for pull).
If you have constructed a system where no pneumatic air is used to retract the piston, then you will need a stopper on one valve port.
For example: if only one port on the cylinder is connected to a valve, when that valve is diverting air to the other output port (say port 4), all connected air stores will be dumped. In this case adding a stopper plug to port 4 and making that port the "home" port will stop air from exiting when the system is being pressurized.
This kind of set up can be used to save air when the cylinder has a return spring or other method of returning the piston to its starting position.
A stopper can be made with a round urethane belt (tube) or use a tee fitting and connect 2 of the openings together with one tube to make a dead end, then connect the tee to your valve port.
