Four-Port, Stainless Steel Barstock, Single Stage Cylinder Regulator for High Purity Gas Applications

The CONCOA 322 Series single-stage regulator is designed for primary pressure control of high purity gases (up to grade 5.5) and mildly reactive gases. It is not suitable for toxic or highly corrosive gases. Single-stage regulators are recommended for applications that can tolerate small fluctuations in outlet pressure due to cylinder depletion, or where the inlet pressure is stable or below 500 PSIG (34 BAR).
