AIRGAS Y12N245D590-AG High Purity Two Stage Pressure Regulator, N245D590

Description: Airgas® Model N245D590 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check ValveNew, Purchased as a spare, but never used. Item Details This series of two-stage, high-purity regulators is designed for non-corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two-stage design yields a delivery pressure of less than 0.02/100 psi inlet change. These regulators come with a CGA-nipple that has a special high-purity, non-lubricated check valve incorporated into nose and 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. This regulator also has both a front and rear panel mount bonnet to allow for easy panel mounting. Convoluted stainless steel diaphragms with metal-to-metal seals provide excellent regulating characteristics and allow for internal vacuum purging. 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. This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels. A diaphragm packless outlet valve with a 1/4" compression fitting is provided for flow control and to maintain system purity. Captured bonnet ports with optional vent adapters are standard on both stages and allow for the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service. Features Encapsulated Filter Seat Assembly: For added gas stream purity and extended service life. Convoluted Stainless Steel Diaphragms: Provides superior leak integrity without contamination from a non-metallic liner or seal. Bonnet Vent Ports (with Optional Bonnet Vent adapters): Allows venting of hazardous gases in the event of diaphragm failure. Metal-to-Metal Seal: For High Purity. Standard Threaded Bonnet (with Optional Collar-Mount Nuts): For easy panel mounting. Diaphragm Packless Valve (with 1/4” Compression Fitting): Promotes system purity. Six Outlet Pressure Ranges: Provides application pressure compatibility. Panel Mount Bonnets: Front and rear.
