The pressure in the single pneumatic line may be varied to launch multiple cement plugs from a cement head. The system may be used to remotely launch a cement plug from a cement head. A wireless remote may be used to regulate the pressure in the pneumatic line to launch cement plugs from the cement head as desired.
