The 212 Series regulator is intended for primary pressure control of non-corrosive, liquefied, or high purity inert gases (up to grade 4.5) in applications requiring constant pressure control and delivery regardless of supply pressure variations. Available with a variety of options installed at the factory, the CONCOA 212 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
