Chrome-plated forged brass, dual stage regulator for low delivery pressure applications
The CONCOA 213 Series regulator provides primary pressure control of non-corrosive, liquefied, or high purity inert gas applications (up to grade 4.5) requiring constant low-pressure control. Two stages of pressure regulation minimize any pressure variation arising from inlet pressure changes, such as the depletion of the supply cylinder, allowing the 213 Series regulator to provide a constant delivery pressure. With delivery pressures as low as 0.1 PSIG (7 mBAR) that can be adjusted in as low as 0.05 PSIG (4 mBAR ) increments, the CONCOA 213 Series regulator satisfies any high purity application with atmospheric delivery pressure requirements below 5 PSIG (350 mBAR).
