The 414 Series regulator provides primary pressure control for non-corrosive, ultra-high purity, or liquified gases. Two stages of pressure regulation minimize pressure variation arising from inlet pressure changes such as the depletion of the supply cylinder, making the 414 Series dual stage regulator ideal for applications where constant delivery pressure is critical. For system flexibility, the CONCOA 414 Series regulator may be installed directly on a top-outlet cylinder or mounted using a bracket and connected to the source via a flexible hose.
