The 402 Series regulator is intended for primary pressure control of non-corrosive, liquefied, or ultra-high purity inert gases. Due to the pressure rise associated with high pressure cylinder depletion, CONCOA recommends single stage regulators for primary pressure control 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 402 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 402 Series regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets.
