The 401 Series single stage regulator is intended for primary pressure control of non-corrosive, ultra-high purity, or liquified gases (up to grade 5.5) in applications that can tolerate minor fluctuations in outlet pressure due to diminishing inlet supply or where inlet pressure is constant or under 500 PSIG (34 BAR). Like almost all CONCOA regulators, the maximum inlet pressure for the 401 Series regulator is at least 3000 PSIG (210 BAR) or greater, depending on system configuration. Available with a variety of options installed at the factory, the CONCOA 401 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
