The HPT 500 brass two
stage regulators are recommended for high purity, non-corrosive
gas applications where constant delivery pressure is required
as cylinder pressures decrease. 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 HPT
500 incorporates advanced design features for maximum safety and
ease of installation in complex piping systems.
