The HPS 500 brass single
stage regulators are recommended for very High Purity inert 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 shut-off valve is optional.
These regulators are
highly recommended for critical high purity cylinder and OEM applications.
They are able to withstand internal vacuums generated during purging
operations. The HPS 500 incorporates advance design features for
maximum safety and ease of installation in complex piping systems.
