CONCOA 420 Series Line Regulator

Six-port, chrome-plated brass, single-stage regulator for ultra-high pressure applications

The CONCOA 492 Series regulator delivers primary pressure control for non-corrosive gases in high-purity, ultra-high-pressure applications. Instead of a diaphragm, it employs a robust piston assembly to safely manage extreme inlet pressures. Factory-installed options allow configuration as a single-station manifold, with or without purge, low-pressure alarm, or multiple inlets.
