QUICK FILL
The “Quick Fill” consists of a quick balanced coupling, disposed on the cylinder valve, which allows the connection and disconnection to a balanced valve connected to the filling source by a
high pressure hose. The graft and valve are balanced to allow the connection and disconnection without any effort. Both sides of the valve (“male” and “female”) have a non-return device, so once disconnected no air leakage is caused. Once connected, the air transfer must be done with limitations to avoid a mechanical stress and overheating. For this reason, the device has a calibrated hole inside the valve, to limit the flow rate to a maximum of 1500 l/min (when the pressure difference between the two connected environments is 300 bar). Such a flow rate enables the complete filling of cylinder of 6,8 l to 225 bar in about one minute, which is considered an optimal compromise between speed and no risk.
