CONCOA 420 Series Cylinder Regulator
Six-Port, SilcoNert® 2000, Single Stage Cylinder Regulator for Reactive Analytical Applications
The CONCOA 420 Series regulator, treated with SilcoNert® 2000, is designed for primary pressure control of reactive or corrosive calibration mixtures and pure gases, providing an extremely inert wetted surface. The proprietary amorphous Silicon CVD coating delivers superior inertness and corrosion resistance compared to bare 316L stainless steel or other alloys. In its six-port configuration, the 420 Series is suitable for applications tolerating minor outlet pressure fluctuations or with gases stored below 500 PSIG (35 BAR). Maximum inlet pressure is at least 3000 PSIG (210 BAR), with optional configurations up to 4500 PSIG (310 BAR). Factory-installed options include single station manifold setup, purge, low-pressure alarm, or multiple inlets.
