These 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 stainless steel diaphragm provides good regulating performance and maximum pruity 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 adaptor enables venting hazardous gases in the event of diaphragm failure.
