  • Choice of quick connects

GSC Assembly Descriptions

Standard version

For general use or for use with GSM systems without a purge option.

Purge-300x132

Purge version

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.
