420 Series Cylinder Regulator

The 420 Series SilcoNert 2000 treated regulator provides primary pressure regulation of reactive or corrosive calibration mixtures or pure gases in applications requiring an extremely inert wetted finish. The proprietary, non-reactive amorphous Silicon CVD coating provides excellent inertness for reactive calibration standards and significantly more corrosion resistance than bare 316L stainless steel or other more expensive alloys. In a six port configuration, the 420 Series regulator is suitable for sole pressure control in applications that can tolerate minor fluctuations in outlet pressure due to diminishing inlet supply or with gases stored at pressures below 500 PSIG (35 BAR). Like almost all CONCOA regulators, the maximum inlet pressure for the 420 Series regulator is at least 3000 PSIG (210 BAR) or greater, depending on system configuration. With available options installed at the factory, the regulator may be configured as a single station manifold with or without purge, low-pressure alarm, or multiple inlets .
