This series of two-stage, ultra high-purity regulators is designed for non-corrosive analytical and process applications where precise flow is not critical. A specially designed, convoluted, stainless steel diaphram provides good regulating performance and maxium putity integrity. These regulators are capable of withstanding an internal vacum and can be provided with a diffusion-resistant valve.
Gas Type: Non-Corrosive
Overview

Model HP722 is a two-stage cylinder regulator in brass barstock designed to provide constant delivery pressure from full to near-empty cylinder conditions. The Model HP722 is suitable for high-purity gas applications, research sample system gases, process analyzer gases, gas chromatography, EPA protocol gases, laser gas systems, and emission monitoring systems.
