The SGS 500 stainless
steel single stage regulators are recommended for very high purity,
reactive gas applications where slight variance in delivery pressure
is acceptable as cylinder pressure decreases. The materials of
construction will not off-gas and contaminate the gas stream.
This design is highly resistant to inboard diffusion of atmospheric
contaminants. A diffusion resistant, packless diaphragm is optional.
These regulators are
highly recommended for critical high purity, mild and non-corrosive
gas, and OEM applications. They are able to withstand internal
vacuums generated during purging operations. The SGS 500 incorporates
advanced design features for maximum safety and ease of installation
in complex piping systems.
