The CONCOA 312 Series is a five-port, chrome-plated brass barstock, dual-stage cylinder regulator designed for high-purity inert gas applications. It provides primary pressure control for non-corrosive, high-purity (up to grade 5.5) or liquefied gases. Its two-stage design reduces pressure fluctuations caused by supply cylinder depletion, making it ideal for applications requiring stable delivery pressure. Configurable at the factory, it can serve as a single-station manifold with options such as purge, low-pressure alarm, or multiple inlets.
