332 Series Regulator

Five-port, stainless steel barstock, dual stage cylinder regulator for high purity gas applications
3323331-01-580 shown

The 332 Series regulator provides primary pressure control for high purity, inert gases (up to grade 5.5), including mildly reactive gases, but not toxic or highly corrosive gases. Two stages of pressure regulation minimize pressure variation arising from inlet pressure changes, such as the depletion of the supply cylinder, making the 332 Series regulator ideal for applications where constant delivery pressure is critical. Available with a variety of options installed at the factory, the CONCOA 332 Series regulator is ideal for university classrooms, laboratories, chemical research, and pharmaceutical manufacturing operations.
