Series 470/480 back pressure gas regulators are made for gas/liquid sampling, gas chromatography, pump pressure and vacuum pressure control, storage vessels, manufacturing processing, laboratory use, and toxic gas analyses. Series 470 devices feature brass barstock bodies for non-corrosive, high-purity applications, while the Series 480 devices have stainless steel bodies. Both regulators incorporate metal-to-metal diaphragm seals to prevent gas contamination. According to the manufacturer, the regulators have maximum inlet pressure of 250 PSIG to 3000 PSIG; helium leak integrity of 1 x 10-9 scc/sec; and temperature range of -40 degrees Fahrenheit to 140 degrees Fahrenheit.
