The CONCOA 402 Series regulator is engineered for reliable primary pressure control of non-corrosive, liquefied, or ultra-high-purity inert gases. Designed as a single-stage regulator, it is ideal for applications that can tolerate minor outlet pressure fluctuations associated with cylinder depletion, or for systems where the inlet pressure is stable or below 500 PSIG (34 BAR).
With a maximum inlet pressure rating of at least 3000 PSIG (210 BAR)—dependent on the selected configuration—the 402 Series delivers robust performance in high-pressure environments. This series can be factory-configured with a wide range of options to suit specific system requirements, including purge assemblies, low-pressure alarms, single-station manifolds, and multiple-inlet configurations.
