Five-port, bare brass barstock, dual stage, bottom-entry cylinder regulator for ultra-high purity inert gas applications
The CONCOA 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.
