Welker's
patented constant pressure Premium Purge Sample Cylinder operates
as an integral part of the total sampling system. It provides
sample collections, storage and transport of liquid or gas samples
at pipeline conditions and can be equipped with mixing capability.
The cylinders include a product valve, precharge valve and burst
discs. Purge valves are built into the end caps-giving you the
advantage of purge without increasing the cylinder's overall
length. All 2-inch sample cylinders are DOT and DNV approved.
