Airgas Two Stage Brass 0-250 psi Analytical Cylinder Regulator With Needle Outlet CGA-540This analytical series of high purity brass, two stage regulators is recommended for non corrosive analytical and process applications where precise pressure control is required. This series is ideally suited for chromatographic carrier gas applications including FID, TCD, ECD, HID, and non corrosive gas mixtures for analytical instrumentation. These units feature stainless steel diaphragms and bar stock bodies with low internal volume and minimal

Aramid high tenacity FR thread

minimum droop and a leak-tight bonnet seal

convoluted

a sintered stainless steel inlet filter and a stainless steel instrument valve

The valve is built into the regulator body reducing the gas path

These regulators are typically used in conjunction with other high-pressure regulators or on house-line systems that limit inlet pressure to 250 psig (except on model N570K the inlet pressure limit is 10 psig)

stable delivery pressure and is capable of withstanding internal vacuum purging

The 820 Series is configurable for most applications

This Laser Regulator is the key component in laser applications

while the encapsulated filter assembly protects the valve seats and extends operating service life

Note: Due to the corrosive nature of the gases used with this regulator
