Airgas Model C645A705 Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threaded SeatThis series of two stage, high purity 316 stainless steel regulators is designed for non corrosive analytical and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 04 100 psi inlet change. Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance, and the threaded seat design allows for internal vacuum

They are also equipped with a reverse-flow check valve to prevent backflow of gas into the regulator on the outlet

Composite bonnets - reduce weight and extend finish in outdoor environments

such as blood gas analysis

Material: Polyethylene

non-corrosive gas applications where precise delivery pressure is critical

two-stage regulators are recommended for analytical

Other CGA-connections are available upon request

The unique design of this regulator provides a continuous sweeping of the high pressure chamber
