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 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 includes our patented Smart Purifier Base and cartridge on the A, B and D series. The CGA nipple has a special high-purity, non-lubricated check valve incorporated into nose, and a safety relief valve to protect the purifier and any equipment downstream.

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 allows for the venting of hazardous gases in the event of diaphragm failure.
