Chrome-plated forged brass, single stage regulator for low delivery pressure applications
The CONCOA 203 Series regulator provides final pressure control of non-corrosive, liquefied, or high purity inert gas applications (up to grade 4.5) requiring constant low-pressure control from low inlet pressure sources. With delivery pressures as low as 0.1 PSIG (7 mBAR), which can be adjusted in as low as 0.05 PSIG (4 mBAR) increments, the 203 Series regulator satisfies high purity applications with atmospheric delivery pressure requirements below 5 PSIG (350 mBAR).
