The unique design of this regulator provides a continuous sweeping of the high pressure chamber. This design is specifically made for processes using analyzers and mixes gases with low levels of the gas components. This sweeping action prevents any drop out or change in the gas mixture and quickly removes any contaminants that may enter the regulator. These nickel plated two-stage ultra-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 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. This series of nickel-plated brass two-stage high purity regulators is designed for non-corrosive analytical, mildly corrosive and process applications requiring precise, stable delivery pressure control. The two-stage design yields a delivery pressure change of less than 0.01/100 psi inlet change. These regulators also have a check valve cylinder connection that prevents contaminates from entering during cylinder changeover.
