Four-port, stainless steel barstock, high flow pipeline regulator for high purity gas applications
The CONCOA 484 Series regulator provide pressure control in high flow gas applications such as bulk gas distribution systems, high purity chamber pressurization, and liquefied hydrocarbon analysis. Internal pressure equalization mitigates the delivery pressure variation from changing flows, which is typical in pipelines. Unlike most pipeline equipment, CONCOA line regulators are rated to full cylinder pressure to ensure safe use in the event of primary pressure control failure.
