A sample cylinder is required for every GSM system and should be ordered separately when purchasing a new GSM. Various configurations of sample cylinder assemblies, defined as Grab Sample Cylinders (GSC), are available.
For general use or for use with GSM systems without a purge option.
For use with GSM systems with a purge option specified.
Note: Regardless of orientation and implementation, the flow direction on all GSC isolation valves is away from the cylinder. Needle valves have a preferential shutoff direction for restraining pressure and the valve will be oriented such that it is best situated for resisting the internal pressure of the cylinder.
