CONCOA 483 Series Regulator

CONCOA 483 Series Regulator

Four-Port, Brass Barstock, High Flow Pipeline Regulator for High Purity Inert Gas Applications

The CONCOA 483 Series regulator is designed for high flow inert gas applications, including bulk gas distribution, high purity chamber pressurization, and liquefied hydrocarbon analysis. Its internal pressure equalization minimizes delivery pressure variations typical in pipeline systems. Rated to full cylinder pressure, the 483 Series ensures safe operation even in the event of primary pressure control failure.
