Airgas - Y12-N245A - Model N245A High Purity Brass Two Stage Gas Regulator, ( Each )

ITEM #: 11258450
Item Details This series of two-stage, high-purity regulators is designed for non-corrosive analytical and process applications requiring precise, stable, delivery pressure two-stage design yields a delivery pressure of less than 0.02/100 psi inlet change. The regulator comes in two models with or without our patented Smart Purifier Base and cartridge on the A, B and D regulator with purifier series includes a safety relief valve to protect the purifier cartridge from over-pressurization. On both the purifier and the standard models, the CGA-nipple has a special high-purity, nonlubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during cylinder change creates consistencies in processes and extends column life in GC 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 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 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 regulators are ultrasonically cleaned for the most demanding high-purity service. Features Encapsulated Filter Seat Assy for added gas stream purity and extended service life Convoluted Stainless Steel Diaphragms provide superior leak integrity without contamination from a non-metallic liner or seal Bonnet Vent Ports (with optional bonnet vent Adapters) allow venting o, f ha, zardous gases in the, event o, f di, aphragm failure Meta, l to Metal Se, al for High Purity Standard Threaded Bonnet (with optional col, la, r-mount nuts), for easy panel mounting Diaphragm Packless Valve (with 1/4" Compression fitting) promotes system purity Four Outlet Pressure Ranges provide application pressure compatibility Panel Mount Bonnets front and rear This listing is for Each.
