The CONCOA 432 Series single-stage regulator provides consistent pressure control for toxic, non-corrosive, and ultra-high purity gas applications in laboratory and industrial environments. Two stages of pressure regulation minimize pressure variation arising from inlet pressure changes such as the depletion of the supply cylinder. Available with a variety of options installed at the factory, the 432 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
