GSC Assembly Descriptions

Swagelok offers two types of GSC assemblies: standard and purge.

Standard Purge
A cylinder assembly for general use or for use with GSM systems without a purge option.   A cylinder assembly for use with GSM systems with a purge option specified.
Standard GSC
Purge GSC

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.

See the Grab Sampling Systems Application Guide for specifics on GSC materials of construction, press-temperature ratings and dimensions.
