Airgas Single Stage Brass 0-100 psi Analytical Cylinder Regulator CGA-590 With Needle OutletThis analytical series of high purity brass single stage regulators is recommended for non corrosive analytical and process applications where precise pressure control is not required. The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Machined from brass bar stock, this regulator body has minimal

The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10–8 ccs helium

Filtered Seat - for added gas stream purity and extended service life

Direct cylinder connection is only permissible when using liquefied compressed gases with vapor pressures below 250 psig such as 1

Round construction and elevated bottom encourage circulation of air around the can to disperse heat and reduce moisture buildup and rusting

minimum droop and a leak-tight bonnet seal

A PCTFE seat provides positive closure and is compatible with a wide range of mildly corrosive or corrosive gases

These single-stage regulators are designed for mildly corrosive gases that attack brass or copper-bearing alloys

They are available with a CGA-cylinder valve connection for use on large cylinders

The composite bonnet and the outlet valve are incorporated into the regulator body to reduce weight

Waste can is made of lead-free

An automatic reseating relief valve protects regulator components from over pressurization
