This series of two-stage, high-purity regulators is designed for non-corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two-stage design yields a delivery pressure of less than 0.02/100 psi inlet change. These regulators come with a CGA-nipple that has a special high-purity, non-lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. This regulator also has both a front and rear panel mount bonnet to allow for easy panel mounting. Convoluted stainless steel diaphragms with metal-to-metal seals 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. A diaphragm packless outlet valve with a 1/4" compression fitting is provided for flow control and to maintain system purity. Captured bonnet ports with optional vent adapters are standard on both stages and allow for the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service.
