These 316 stainless steel single-stage high-purity regulators are recommended for non-corrosive analytical, mildly corrosive and process applications where precise flow control is not critical. A specially designed, convoluted Hastelloy C-22 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. 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 enables venting hazardous gases in the event of diaphragm failure.
