This two-stage stainless steel, high-purity regulator has been designed to provide precise pressure regulation for the Airgas EPA Protocol Mercury Standards. The two-stage body, diaphragms, internal carriers, internal compression members, 0.06 Cv poppets, conical compression springs, 1/4" compression fitting and CGA-660 nipple are all passivated using a proprietary coating. This unique coating mitigates the chances of any level of mercury attaching to the internal wetted components of this specialty regulator. The result is a two-stage pressure regulator that will not hold back or alter any level (PPM or PPB) of the mercury standard. The internal threadless seat design of the two-stage stainless steel regulator is the same as used in our high-purity Y12-C445 series. The convoluted Hastelloy C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging. An outlet 1/4" compression fitting is provided to maintain optimum system purity.

Features
Filtered Seat for added gas stream purity and extended service life. Convoluted 316 Stainless Steel Diaphragms provide superior leak integrity without contamination from a non-metallic liner or seal. Bonnet Vent Ports (with optional bonnet vent adapters) allow venting of hazardous gases in the event of diaphragm failure. Standard Threaded Bonnet (with optional collar-mount nuts) for easy panel mounting. Diaphragm Packless Valve (with 1/4" Compression fitting) promotes system purity. Four Outlet Pressure Ranges provide application pressure compatibility.

Product Attributes
This series of two-stage, high-purity 316 stainless steel regulators is designed for non-corrosive analytical and process applications requiring precise, stable delivery pressure control. The two-stage design yields a delivery pressure change of less than 0.04/100 psi inlet change. Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance, and the threaded-seat design allows 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 10–8ccs 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 the venting of hazardous gases in the event of diaphragm failure. These regulators are ultrasonically cleaned for the most demanding high-purity service.
