This series of stainless steel single-stage regulators are designed to have minimal gas paths in the regulators and prevent contaminants from entering during cylinder change out. These regulators have a check valve cylinder connection, packless diaphragm valve built into the regulator, and a 8" stainless steel compression fitting on the outlet. The regulator also has a unique design that causes the gas to continuously sweep the diaphragm chamber ensuring that there is no air or other contaminants in the regulator body. The diaphragm valve built into the body shortens the gas path allowing the gas to enter the process faster and without contamination. This is an excellent regulator for EPA protocol gas mixtures, as well as other mixes used in high purity applications. Convoluted Hastelloy® C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging the metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10-8 ccs helium. This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels. Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service.
