Six-port, bare brass barstock, dual stage cylinder regulator for ultra-high purity inert gas applications
The CONCOA 412 Series regulator provides primary pressure control for ultra-high purity inert gases. Two stages of pressure regulation minimize pressure variation arising from inlet pressure changes, such as the depletion of the supply cylinder. The 412 Series dual stage regulator is ideal for applications such as gas supply to analytical instruments, where constant delivery pressure is critical. Available with a variety of options installed at the factory, the 412 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
