A system for forming a container from a preform, the system comprising: a preform or a container having a finish; a nozzle that is adapted for directing a fluid through an opening of the finish of the preform or container connected to the nozzle; a seal pin openable from a closed position to open a nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage and through the opening of the finish to simultaneously form the container from the preform and fill the container; a sensor that determines position of the seal pin; wherein the system is configured for simultaneously forming the container from a preform and filling the container with a fluid; a fluid cylinder that is adapted for controlling the velocity of fluid to the nozzle is provided; a control module is provided configured to: increase velocity of fluid to the nozzle with the fluid cylinder; and open the seal pin to open the nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage; the system being characterized in being adapted such as to control a set fill velocity of the fluid cylinder to a maximum fill velocity when the nozzle passage is opened such that an area of the nozzle passage is equal to or greater than the effective fill area at the opening of the finish; and close the seal pin to close the nozzle passage after the container is formed and filled. a nozzle that is adapted for directing a fluid through an opening of the finish of the preform or container connected to the nozzle; a seal pin openable from a closed position to open a nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage and through the opening of the finish to simultaneously form the container from the preform and fill the container; a sensor that determines position of the seal pin; wherein the system is configured for simultaneously forming the container from a preform and filling the container with a fluid; a fluid cylinder that is adapted for controlling the velocity of fluid to the nozzle is provided; a control module is provided configured to: increase velocity of fluid to the nozzle with the fluid cylinder; and open the seal pin to open the nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage; the system being characterized in being adapted such as to control a set fill velocity of the fluid cylinder to a maximum fill velocity when the nozzle passage is opened such that an area of the nozzle passage is equal to or greater than the effective fill area at the opening of the finish; and close the seal pin to close the nozzle passage after the container is formed and filled. increase velocity of fluid to the nozzle with the fluid cylinder; and open the seal pin to open the nozzle passage of the nozzle to allow the fluid to flow through the nozzle passage; the system being characterized in being adapted such as to control a set fill velocity of the fluid cylinder to a maximum fill velocity when the nozzle passage is opened such that an area of the nozzle passage is equal to or greater than the effective fill area at the opening of the finish; and close the seal pin to close the nozzle passage after the container is formed and filled.
