These two-stage regulators are specifically designed for low-flow, non-corrosive gas applications where precise delivery pressure is critical. They feature a brass piston sensor in the first stage, a stainless steel diaphragm in the second stage and a preset safety relief valve. A sintered brass filter protects internal parts. These two-stage regulators are also ideal for medical diagnostic applications, such as blood gas analysis, where precise pressure control and low flow rates are required. They are available with 973 pin-indexed yoke connection for use with E medical cylinders. Not to be used for human consumption or digestion.

Product Attributes
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.
