Nitrogen purging is used to dry and decontaminate the container by evacuating the air inside it. Purging can be done automatically, before, during, and after the filling cycle. The purging of a drum is done by forcing nitrogen gas through the filling lance into the container.
The standard filler lance has a glass-filled, Teflon sealed foot valve at the end of the filler lance. It is a 316 stainless steel, machined spool, raised and lowered by a solid rod inside the lance tubing that is activated by an air cylinder at the top of the lance.
The valve rod will be hollow and the machined spool of the foot valve will be hollowed out so that a purge of Nitrogen will flow through the rod and the foot valve, into the container. The purge can be set to run automatically from 1 to 999 seconds, or 1 to 999 minutes.
