These brass, single-stage, high-purity regulators are recommended for non-corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. The regulator comes in two models with or without our patented Smart Purifier Base and cartridge on the A, B and D series. The 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, 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. Each regulator is capable of withstanding an internal vacuum and is provided with a diffusion-resistant, diaphragm packless outlet valve to maintain system purity. The optional bonnet vent Adapter allows for the venting of hazardous gases in the event of diaphragm failure.
